a isdn question about ddr and nat

[xuyong]

 Hello,
I have a problem about isdn DDR?

One Cisco 3620 router, isdn bri interface.I config it as DDR. I used dynamic 
NAT.The public interface(bri 0/0) ip is negotiated.
 Now I can ping the internet webside on my router.But I can't ping it successfully 
on my workstation. I debug NAT. I find the first packet is successfully translated for 
request and reply when I ping webside from my workstation, but the other three are 
only translated for request, no reply.  What's the problem?
 
 Thanks a lot
 
 sincerely,
stephen xu

AW: exam 640-647(voice)

[Udo Konstantin]

It's hard to learn for the voice exam. Because its one of the exames which
are really confused.
A good way is to learn _all_ about the call manager...especially the specs
for CISCO products.

That is all what I can say

Re: Slightly OT - Setting up syslog on Solaris for Remote logging of Cisco Routers

[Sasa Milic]

I'm using syslog on Solaris, and I'm logging messages from cisco
on it. Didn't have to configure anything special, except
/etc/syslog.conf file:

#
local5.debug/var/log/cisco/debug
local7.debug/var/log/cisco/log
#

One pretty offen problem arise if you don't use TABs in syslogd
config file - it just won't work. So, remove all spaces (0x20)
and use TABs instead of them, and it should work.

Hope this helps.

RE: Cisco1600 ISDN + D channell

[Timothy Metz]

My telecom had announced a service (for consumers) where you had an "always
on" D channel that could be used for email only at $5 a month. It never
materialized and I have no idea how they would have implemented this on the
head end.

Re: EIGRP Updates

[Groupstudy]

EIGRP does not make regular table updates, and it only sends partial routes
when there is a topology change.  It does send hellos every 5 seconds
(changeable default parameter) though to allow for rapid reconvergence.   It
acts a lot like BGP when it comes to table updates.

RE: Browsing across subnets...

[Timothy Metz]

I had the same problem and fixed it with ip helper-address. Your goal here
is to get netbios broadcasts forwarded to the destination network. I don't
quite remember if the helper address in this case should be the network
address or the broadcast address (I'm not at work to check) but someone will
correct me if I'm wrong.


Network A 192.168.10.X/24
Network B 192.168.20.X/24

on the interface that is directly connected to network A type

(config-if)#ip helper-address 192.168.20.0

and on the interface that is directly connected to network B type the
opposite

(config-if)#ip helper-address 192.168.10.0

Re: IBGP multihop?

[Groupstudy]

Look at the name of the command, it sums up where you can use it 'EBGP
multihop'...you can only use this command to reference neighbors in a
different AS than the router originating the command.

Re: EIGRP Updates

[EA Louie]

EIGRP does not update topology or routes unless the routes actually change.

When the routes do change, EIGRP will take up to 50% of the available
bandwidth transmitting updated routes unless limited by the

ip bandwidth eigrp  
appletalk eigrp-bandwidth 
ipx bandwith-percent eigrp  

statements

RE: Cisco1600 ISDN + D channell

[Damien Kelly]

I have heard of two scenarios.  1 was used.  probably with a PRI, European
standards Europe PRI = 30B + D and a BRI, they were able to establish a link
with the two D channels and send TCP keepalives.  free 16k fixed connection.
not really practical for much.  but hey it was free.  Not that it mattered,
they were a telco.

It was also suggested that using two Cisco 1600's each with a BRI configured
for dial on demand, that one could initiate a call to the other over the D
channel to allow the router making the call to bring up the B channels on
remote router, initiating a call to the internet where the router could then
be access via IP.  

I want to know if this is possible so I can better support a remote office
on dialup, when there are network issues.

Any ideas?

Thanks  Damien

Re: OSPF

[EA Louie]

2 reasons an organization would use OSPF -

1.  It's a standards-based protocol, which means that you could run any (not
just Cisco) OSPF devices in your network and they'll interoperate.
2.  It's "controllable", so that you can keep your routing tables smaller by
using area routing

disadvantages (according to Cisco) of OSPF versus EIGRP is that it uses more
CPU

I've never worked in the ISP environment, but I'd imagine that they need to
use some sort of IGP within their BGP domains, and if they do use an IGP,
OSPF would probably be their choice because of the multi-vendor support.

how to translate the destination IP using (LINUX IPchains andMas querading)

[Sim, CT (Chee Tong)]

Any one familiar with Ipchains??

I just built a LINUX firewall between two network in our company 

Network A:60.100.100.0/24, interface IP eth0 in A is 60.100.100.101
Network B:192.168.3.0/24, interface IP eth1 in B is 192.168.3.2

>From my workstation (60.100.100.99), I want to connect to a SERVER
(192.168.3.100) in network B using a FAKE address in network A
60.100.100.102.

First I did a proxy ARP to map 192.100.100.102 IP to 60.100.100.101's MAC
address.

So, I want to translate source IP from 60.100.100.0 network to firewall
interface IP in B 192.168.3.2 when it go out from firewall and I can do it
using Ipchains command in Linux "ipchains -A forward -i eth1 -s
60.100.100.0/24 -j
MASQ 
(I don't want to change server's routing table)

But I also need to translate the destination IP from 60.100.100.102 to
192.168.3.100 while it is in Linux firewall.  What is the command to do it
in Linux way??  Can it be done???

Thanks

Re: [TFTP Error - Part 2]

[EA Louie]

unfortunately, it's not IOS specific.  In the boot process, the router loads
the IOS from flash, recovers the configuration from NVRAM, and goes through
all the interfaces and decides whether they're in an up, down, or shutdown
state.  Until it finishes all those processes, there's no configuration
access to it.

regarding your tftp problem, did you post the configuration in an earlier
email?  (If so, I missed it and would you repost it?)

Oracle Error

[Ramesh c]

Hi,
I am trying to install Oracle 8i(8.1.6)on RedHat linux 7.0.(2.2.16-22)The Glib which 
comes along with RedHat is glibc 2.2 

The installation of Oracle is successful.But when I try to create a database I get the 
following error message.
svrmgrl>
"ORA-03113 end-of-file on communication channel" 
svrmgrl>

I tried downgrading to glibc2.1 and started the Svrmgrl ..still the result is same.I 
also tried fresh install of Oracle after downgrading to glibc2.1 ..oracle installation 
fails.

I guess many have faced this problem.Is there any solution for the same.if so what is 
it?

Any help would be highly appreciated.

thanks
Regards
Govind

Just point both routers at the same syslog server. You can change each
routers facility to make it easier to differentiate which is which but I
don't think that's mandatory.

on an e1 PRI ISDN controller you can configure the nfas_d D Channel timeslot

  k Maximum number of outstanding frames (window size)

has anyone ever configured these variables, & if so to fix what problems?

also, does anyone know why BRI is represented as 192K total in some books
(I though 2B=2x64 + D =16K)

US PRI = 23B + 2 D  how big is D (54K?)
Europe PRI = 30B + D (64K)

what would the carrier use for signalling if the D channel was taken?

There is a manual "break" as well  Put a break-out box between the

during boot-up.  This will kick you instantly into rommon where you can
change the confreg settings

The config reg setting of 0x3920 is the Console port set to 115200,8,N,1.
You can either set your Hyperterm to the previously mentioned settings or

I have no idea why or what you have done (0x3920 :-)  The only superior
BREAK command I know is to lower Hyper Term to 1200 (reset the Hyper Term
window) & power the router off/on.  Hold the space bar for 5 seconds while
powering the router on, you should see some garble in the top left of the
screen (may have to do this a couple of times for it to take).  This sends
the manual BREAK signal that commands sometimes do not.  Lastly- change
everything back.  Other than the above, call the TAC or pull the FLASH so it
will only boot to ROM (then change your config values back to 0x2102 or o/r
0x42).

Let us know how you make out !!!

CiscoWorks 2000 vs. CiscoWorks for Windows

[Jeff Walzer]

We have a Frame Relay network that connects 8 remote locations. Our
locations have a combo of 3548 and 2924 Cisco switches. There are only two
IT guys in one location and we want to be able to monitor each location
using a protocol analyzer. Does either CiscoWorks 2000 or CiscoWorks for
Windows allow this capability? Or do I have to go with a solution from
EtherPeek or NAI's Sniffer products?

We are interested in seeing traffic, utilization, problems (errors,
collisions, etc) on all of our LANs from one central location.

Thanks,

Re: Sample CCNA test question..bogus?

[Adam Hickey]

It would appear to me that by the statement 172.16.0.0/19 they are stating a
major net rather than one of the subnets created by the masking. If you look
carefully at the answers, D is the only one that can be right because it is
the only one that qualifies as a host address. A) 172.16.32.0 = a subnet
address,  B) 172.16.64.0 = a subnet address, C) 172.16.63.255 = a broadcast
address within a subnet, D) 172.16.80.255 = a host address within a subnet.

If I am wrong, it wouldn't be the first time. but that's what I see.

allowsd isdn on the d channel for a BRI x25 connection IOS 12.1.2
Desktop

on an e1 PRI ISDN controller you can configure the nfas_d D Channel
timeslot
to be backup, primary or 'none' which permits it to be a B channel

which should show up under sh isdn serv as an available channel
never actually done it myself

as for BRI I've never heard of it being don
although you can configure lapb (b channel) variables:
  N1Maximum number of bits per I-frame
  N2Maximum number of attempts to transmit a frame
  T1Retransmission timer
  T2Explicit acknowledge deferral timer
  T4Keepalive timer
  interface-outage  Interface outage deadband (partial T3)
  k Maximum number of outstanding frames (window size)
  moduloSet frame numbering modulus

has anyone ever configured these variables, & if so to fix what
problems?

also, does anyone know why BRI is represented as 192K total in some
books
(I though 2B=2x64 + D =16K)

US PRI = 23B + 2 D  how big is D (54K?)
Europe PRI = 30B + D (64K)

what would the carrier use for signalling if the D channel was taken?

I saw that there is isdn technology that allows data to pass along the

it.
I do not know how commercially available this is.  Only use I could

is you could then use it for dial on demand inbound, but do you want
that.

Well, since I'm not a qualified psychiatrist I don't want to comment on =
your mental
health, but there is a correct answer here.  If we go to binary it all =
becomes clear.

The /19 means that the first 19 bits are network/subnetwork bits and the =
remaining 13
bits are host bits.  Therefore our mask would look like this:
..1110.

Since the first two octects are identical, we can dispense with them and =
concentrate on
the first 3 bits of the third octet and the remaining host bits.

Our subnet addresses would be as follows:

X.X.. =3D X.X.0.0 Hosts =3D X.X.0.1 - X.X.31.254 Bdcst =3D =
X.X.31.255*
*Assumes Subnet Zero Allowed
X.X.0010. =3D X.X.32.0 Hosts =3D X.X.32.1 - X.X.63.254 Bdcst =

X.X.0100. =3D X.X.64.0 Hosts =3D X.X.64.1 - X.X.95.254 Bdcst =

X.X.0110. =3D X.X.96.0 Etcetera, Etcetera

.
Etcetera (You get the picture)

RE: Sample CCNA test question..bogus?

[Dusty Harper]

Just to elaborate on Adam's answer  

If you are using CIDR (allows 0 and 255 as networks) you have a
total of 8 networks (2^3)
This leaves you with 8190 hosts per network (2^13 - 2)

The network ranges (256 - 224 = 32 )  (you get the 224 by
counting the 1's in this case 1110)

The hosts range between the network addresses (this accounts for
the subnet address and broadcast address)

172.31.0.0   - 172.31.31.255
172.31.32.0  - 172.31.63.255
172.31.64.0  - 172.31.95.255
172.31.96.0  - 172.31.127.255
172.31.128.0 - 172.31.159.255
172.31.160.0 - 172.31.191.255
172.31.192.0 - 172.31.223.255
172.31.224.0 - 172.31.255.255

So the answer is D

It would appear to me that by the statement 172.16.0.0/19 they are
stating a
major net rather than one of the subnets created by the masking. If you
look
carefully at the answers, D is the only one that can be right because it
is
the only one that qualifies as a host address. A) 172.16.32.0 = a subnet
address,  B) 172.16.64.0 = a subnet address, C) 172.16.63.255 = a
broadcast
address within a subnet, D) 172.16.80.255 = a host address within a
subnet.

If I am wrong, it wouldn't be the first time. but that's what I see.

AS5300 radius

[Dale Frohman]

Quick question for the group.  I have an AS5300 that i thought i had setup
for two radius servers, however we had a situation where the primary
radius server went down and the 5300 did not switch to use the secondary.
I had to remove the primary in order for the secondary to work.

Here is what i had configured:

radius-server host x.x.x.x auth-port 1812 acct-port 1813 non-standard
radius-server host x.x.x.x auth-port 1812 acct-port 1813 non-standard

[Hinds, Jarrett]

The question is just worded badly.  It seems that the writer meant to ask:

1. If you were given the whole 172.16.0.0 network to use and you chose a /19
subnet mask to subnet it with, which of the folowing answers would be a
valid host in ONE of the resulting subnets.

versus

2. Which one of the following is a valid host using the address of
172.16.0.0 /19?

Those are two different questions with distinct answers.  Answer D is
feasible for question 1, but not for question 2.

a. 172.16.32.0

b. 172.16.64.0

c. 172.16.63.255

d. 172.16.80.255

CAT 5000 what does port status "inactive" mean?

I have a catalyst switch and a number of its ports are showing up as inactive.

The cisco web page does not list inactive as one of the possible values in

Anyone know what this means?
They were not connected until I assigned them to a VLAN, then they showed
up as inactive

Re: Sample CCNA test question..bogus?

[Kelly D Griffin]

If the question were:

Q. Which one of the following is a valid host using the address of
172.16.64.0 /19?

Answer D would be valid.

Q. Which of the following is a valid host using the address of
172.16.0.0/24?

a. 172.16.254.12
b. 172.16.0.255
c. 172.16.0.0
d. 172.16.255.255

What is the answer to this question?  When I do design work and send clients
a design that includes the subnets they should route to my campus, I do not
say 172.16.0.0/19 and mean 172.16.64.0/19.

Re: Sample CCNA test question..bogus?

[John Neiberger]

I think I'll side with those who say there is no correct answer, but
there is an answer that's closer to being correct than the others.  :-)

The question is asking for a valid host in the 172.16.0.0/19 range. 
Answer D is not in that range!  It is in the 172.16.64.0/19 network. 
Valid host addresses in the 172.16.0.0/19 range are:

172.16.0.1 through 172.16.31.254

I would agree that by making a subtle adjustment to the question,
answer D is the only answer possible.  Given a /19 prefix length, the
only possible host address given in the answers is D, which forces us to
change the question to fit the answer.

This just appears to be a poorly worded question that not only allows
you to figure out the most-correct answer eventually but also forces you
to deduce what the actual question is in the first place.In other
words, it's a typical Cisco test question!

Regards,
John

Greetings all,

I never really paid attention to this before till someone asked the

only and the other Read/Write:


System flash directory, partition 1:
File  Length   Name/status
  1   7992252  /c2500-j-l_112-17.bin
[7992316 bytes used, 396292 available, 8388608 total]
8192K bytes of processor board System flash (Read ONLY)


System flash directory, partition 2:
File  Length   Name/status
  1   7992252  c2500-j-l_112-17.bin
[7992316 bytes used, 396292 available, 8388608 total]
8192K bytes of processor board System flash (Read/Write)

Any input

Thanks,

Nabil

PIX Question on VPNs

[Vijay Ramcharan]

Hi everyone,
I have a question on the operation of VPNs when using a PIX and connecting
via PPTP from a Win2K client.

Suppose I have a PIX that is setup to accept PPTP connections and
dynamically assign the client an IP address from a LAN subnet after they've
been authenticated on the PIX.
After the VPN tunnel is established, is it possible to go to a website while
the tunnel is active?
The NAT (inside) 0  command is used on the PIX.

RE: AS5300 radius

[Jim Dixon]

I believe that you can specify up to three methods of auth to use
for each aaa line.  the radius local says that first use Radius to auth
then after failing there use the Local Auth setup on the 5300.

Feel free to correct me if I am wrong here.

Re: Sample CCNA test question..bogus?

[Lowell Sharrah]

I believe that answer D is correct and here is why

Vaslid hosts in the network 172.16.0.0/19 are as follows

172.16.64.1-172.16.95.254 
172.16.128.1-172.16.159.254
172.16.192.1-172.16.223.254
172.16.32.1-172.16.63.265
172.16.160.1-172.16.191.254
172.16.96.1-172.16.127.254
.255 is broadcast 

>>> "John Neiberger" <[EMAIL PROTECTED]> 03/15/01 11:19AM >>>
I think I'll side with those who say there is no correct answer, but
there is an answer that's closer to being correct than the others.  :-)

The question is asking for a valid host in the 172.16.0.0/19 range. 
Answer D is not in that range!  It is in the 172.16.64.0/19 network. 
Valid host addresses in the 172.16.0.0/19 range are:

172.16.0.1 through 172.16.31.254

I would agree that by making a subtle adjustment to the question,
answer D is the only answer possible.  Given a /19 prefix length, the
only possible host address given in the answers is D, which forces us to
change the question to fit the answer.

This just appears to be a poorly worded question that not only allows
you to figure out the most-correct answer eventually but also forces you
to deduce what the actual question is in the first place.In other
words, it's a typical Cisco test question!

Discontiguous networks

[Arthur Simplina]

I know that there was an earlier posting and a very good explanation on 
this. So, kindly bear with me.

I am trying to figure out the subnets (and hosts) for this address:

192.10.3.0 with subnet mask 255.255.255.148.

I am asking this out of curiosity and to learn how to go about this.

Thanks for any help.

Re: DCE to DTE no CSU/DSUs

[Bob Timmons]

If you're using a back-to-back cable, the DCE will ALWAYS be the router with
the DCE side
of the cable.  If you're doing frame-relay, and using 1 router to be the
frame-relay switch, you'd
typically use the DCE side of the back-to-back on the frame-switch for all
routers connected
to the frame-relay switch.  You would then set your desired clock rate on
each serial interface.

Re: Sample CCNA test question..bogus?

[John Neiberger]

I disagree.  Valid hosts in 172.16.0.0/19 are:

172.16.0.1 through 172.16.31.255

I guarantee you that any other interpretation will make life miserable
for you eventually, especially in a production environment where you
actually use CIDR or VLSM.  A good example would be if you were running
BGP in a production environment that actually connected to the internet.
 

Let's say you were Joe's ISP and were assigned 172.16.0.0/19.  This is
*very* specific...you can only advertise 172.16.0.1 through
172.16.31.254.  Most likely, 172.16.32.1 through 172.16.63.254 is going
to be assigned to someone else.  If you followed your logic and
advertise the entire 172.16.0.0/16, you will be getting some nasty phone
calls or nastygrams in your email box.  Companies tend to get a little
upset with you if you start advertising their address block.

In that spirit, I assume when a test question says something as
specific as 172.16.0.0/19 that they *really* mean it.

Re: Browsing across subnets...

[The.Rock]

He's exactly right!!! That is how you fix it. Also you can have a WINS
server on both subnets and you need to setup replication between the two.
Although this doesn't always work like you want it to. Sometimes it takes a
long time to update the browse list depending on how big your network is.

Re: Flash memory question

[The.Rock]

You will be able to overwrite the flash file with a newer one(or whatever),
it will ask you first if you want to erase flash before coming the IOS over.
If not just take the memory out and reverse the slots and then do "erase

Re: Sample CCNA test question..bogus?

[John Neiberger]

How could the wording be correct?  172.16.80.255 is a host address in
172.16.64.0/19, *not* 172.16.0.0/19.   There is no correct answer
provided to that specific question as worded. I agree that it is trying
to be a trick question, but it fails because of poor wording or a typo. 
Perhaps one of the answers should have been 172.16.15.255 or something
like that.  That would have been tricky yet also correct given the
question that was being asked.

John

>>> "Arthur Simplina" <[EMAIL PROTECTED]> 3/15/01 9:51:53 AM >>>
I think the trick part of question here is that the answer d.
172.16.80.255 
seems like a broadcast address because of the 255 (all 1's in the last

octec.) So now the test taker faces the dilemna of choosing between two

subnetwork addressess and two "broadcast" addresses.

Cisco would want to know if you really know subnetting. Hence, the
wording 
of the question (which to my opinion is still correct).

Quality Labs

[Maccubbin, Duncan]

I am looking for some quality labs to practice with. Perhaps someone who has
taken the CCIE lab recently can comment on some prep labs they have used
that they thought were good. I'd rather not buy 10 bad practice labs to get
one good one.

Re: Discontiguous networks

[John Neiberger]

ouch!  Please do not attempt this at home.  Heck, please do not attempt
this anywhere!  :-)

The binary mask for last octet would be 1010. If you assume the use
of subnet zero, your host address go from 1 to 31, then skip to 64-94. 
The next subnet in binary is 0010 so the network address is
192.10.3.32 and host address are 33-63 and 95-126.  This is painful,
it's making my head hurt

Okay then, the next subnet in binary is 1000, or .128 in decimal,
and your host addresses are 129-159 and 192-223.  The final subnet is
1010, or .148 and the host addresses are 149-180 and 224-254.

I think.  That is really painful to think through and I was interrupted
multiple times while trying to write this.  Please forgive me if these
numbers aren't correct.  

And always remember:  Friends don't let friends use discontiguous
subnet masks!

>>> "Arthur Simplina" <[EMAIL PROTECTED]> 3/15/01 10:04:17 AM >>>
I know that there was an earlier posting and a very good explanation on

I am trying to figure out the subnets (and hosts) for this address:

That is not a valid subnet mask.  Subnet mask octets can only be:

   255 = 
   254 = 1110
   252 = 1100
   248 = 1000
   240 =

   192 = 1100
   128 = 1000

Re: DCE to DTE no CSU/DSUs

[Pamela Forsyth]

There are two different issues here that people tend to get confused
about.  Remember the OSI 7-layer model, particularly the lower two layers?

OK.  Physical layer.  The clocking on the wire is a physical-layer
function. If you have a back-to-back cable between 2 routers (no csu/dsu),
then one needs to take teh place of the csu/dsu with respect to providing
clocking on the wire.  That would be the router with the DCE end of the
cable attached.  That's where you put the "clock rate" statement.

Let's move up to layer two, the data-link layer.  The data link layer has
no awareness of how that cable works or who is providing clock.  This is
where frame relay lives.  So, if frame relay has no awareness of clock
rate, which implies physical-layer DCE/DTE issues, it stands to reason
that the frame-relay DCE function can be assigned to either of the router
interfaces attached to a back-to-back cable.  And indeed, this is the
case.

Frame relay user-to-network interface has a "user" side and a
"network" side.  The "network" side (where the "cloud," or the
frame-relay switch, would normally be) has the frame-relay DCE function to
perform in terms of LMI.  What you're saying with the "frame-relay
intf-type dce" statement is, "this interface is on the network side of
this UNI connection and needs to perform LMI functions just as a switch
would.  I am expecting the device connected to me to act as a router (user
side)."

So, to sum up, if you have a back-to-back serial cable connection between
two routers, the "clock rate" statment MUST go on the interface where the
DCE side of the cable is attached.  If you are using frame-relay
encapsulation with one router acting as a frame-relay switch, the
"frame-relay intf-type dce" statment MUST be on the switch interface.  The
frame-relay and physical-layer DCE functions do not relate to each other
in any way.

Re: Sample CCNA test question..bogus?

[Craig Columbus]

John's right on track here.  When using the /19 notation with 172.16.0.0, 
you're referring to that specific network.  172.16.0.0/19 is not the same 
network as 172.16.64.0/19.
Reading this question a little bit differently, I can see that perhaps 
there is a typo...if the question used a /18 instead of a /19, then answer 
"A" would be correct.
If you want to make answer "D" correct, you either need to rephrase the 
question to "Which one is a valid host using 172.16.64.0/19?" or rephrase 
the question to "Which one is a valid host using 172.16.0.0/17?", which 
would allow for ALL of the answers to be correct.

Re: Sample CCNA test question..bogus?

[Lowell Sharrah]

this is assuming vlsm.  when you have a class network with varibale bits in the subnet 
mask that is different than the default subnet mask, you have multiple subnets and 
multiple host on each subnet.  This question is telling us that there are 3 bits as 
subnet bits (since the default for class B networks is 16) and the remaining 13 are 
host bits.  This arnagement (172.16.0.0/19) calculates out to be more than one subnet 
and answer d falls in one of the valid subnet ranges.  If thew question was worded 
differently with a particular subnet such as 172.16.30.x/19, then it would not be true.

>>> "John Neiberger" <[EMAIL PROTECTED]> 03/15/01 12:04PM >>>
How could the wording be correct?  172.16.80.255 is a host address in
172.16.64.0/19, *not* 172.16.0.0/19.   There is no correct answer
provided to that specific question as worded. I agree that it is trying
to be a trick question, but it fails because of poor wording or a typo. 
Perhaps one of the answers should have been 172.16.15.255 or something
like that.  That would have been tricky yet also correct given the
question that was being asked.

John

>>> "Arthur Simplina" <[EMAIL PROTECTED]> 3/15/01 9:51:53 AM >>>
I think the trick part of question here is that the answer d.
172.16.80.255 
seems like a broadcast address because of the 255 (all 1's in the last

octec.) So now the test taker faces the dilemna of choosing between two

subnetwork addressess and two "broadcast" addresses.

Cisco would want to know if you really know subnetting. Hence, the
wording 
of the question (which to my opinion is still correct).

Best Training Partner

[exchange]

Hi there,

I am planning to take two training classes, BSCN and Pix Firewall class.
Can somebody give me a recommendation of a good classroom training
partner?  Only comments I have seen in this group is about
GlobalKnowledge.  Any other  providers or should I go with them for
training.  I would like to take it in the San Francisco Bay Area.  

Thanks!

also note in your reading that EIGRP is Flat where OSPF is hierarchical similar to BGP.

RE: Sample CCNA test question..bogus?

[Jim Brown]

I believe the "best" answer, this is always the kicker, is D. We all know we
are searching for the best answer, or the one the test designer thinks is
correct.

It is the only one that is not a broadcast or network address using the /19
mask.

It is a poorly worded question, but we are faced with those on any test.

John's right on track here.  When using the /19 notation with 172.16.0.0, 
you're referring to that specific network.  172.16.0.0/19 is not the same 
network as 172.16.64.0/19.
Reading this question a little bit differently, I can see that perhaps 
there is a typo...if the question used a /18 instead of a /19, then answer 
"A" would be correct.
If you want to make answer "D" correct, you either need to rephrase the 
question to "Which one is a valid host using 172.16.64.0/19?" or rephrase 
the question to "Which one is a valid host using 172.16.0.0/17?", which 
would allow for ALL of the answers to be correct.

Re: Discontiguous networks

[John Neiberger]

Ah, this is true.  For some reason that didn't even occur to me when I
answered the question.  Now, if you were to invert everything and use
these as wildcard masks, would that work?  I seem to remember that we
had this discussion about discontiguous wildcard masks.  

Regardless, even if discontiguous wildcard masks are allowed, using
them would be bad idea unless you had a very, very good reason for doing
so.  Troubleshooting would be a nightmare.

That is not a valid subnet mask.  Subnet mask octets can only be:

   255 = 
   254 = 1110
   252 = 1100
   248 = 1000
   240 = 
   224 = 1110
   192 = 1100
   128 = 1000
 0 =

Re: Sample CCNA test question..bogus?

[Tom Lisa]

Bruce,

I disagree that the question is asking for a valid host in the 0 subnet.  It is only
stating the network address and mask.  Assuming classful addressing (as the CCNA exam
does), from that you have to determine what would be the valid host ranges given that
mask.  Anyway, that is my interpretation of the question.  BTW, where is this question
from?

RE: OSPF

[Brant Stevens]

The use of IP address summarization creates FS query boundaries, and gives
you a sense of hierarchy, but, you are correct in that there is not an
area-based hierarchical system...

Re: Sample CCNA test question..bogus?

[John Neiberger]

Okay, let's rephrase the question:

You have variably subnetted 172.16.0.0/16 using a /19 mask.  Someone
working with you is configuring a server to be placed at a remote
location that is on the 172.16.0.0/19 network, and he asks you for a
valid host address.

Would you tell him to use 172.16.80.255?  I don't think so.  You would
make sure he uses an address from the 172.16.0.0/19 subnet, so it would
have to be in the range 172.16.0.1 through 172.16.31.254.

And for the very same reason, I feel that D is not a good answer as the
original question is worded.

John

>>> "Lowell Sharrah" <[EMAIL PROTECTED]> 3/15/01 11:10:10 AM >>>
this is assuming vlsm.  when you have a class network with varibale
bits in the subnet mask that is different than the default subnet mask,
you have multiple subnets and multiple host on each subnet.  This
question is telling us that there are 3 bits as subnet bits (since the
default for class B networks is 16) and the remaining 13 are host bits. 
This arnagement (172.16.0.0/19) calculates out to be more than one
subnet and answer d falls in one of the valid subnet ranges.  If thew
question was worded differently with a particular subnet such as
172.16.30.x/19, then it would not be true.

>>> "John Neiberger" <[EMAIL PROTECTED]> 03/15/01 12:04PM
>>>
How could the wording be correct?  172.16.80.255 is a host address in
172.16.64.0/19, *not* 172.16.0.0/19.   There is no correct answer
provided to that specific question as worded. I agree that it is
trying
to be a trick question, but it fails because of poor wording or a typo.

Perhaps one of the answers should have been 172.16.15.255 or something
like that.  That would have been tricky yet also correct given the
question that was being asked.

John

>>> "Arthur Simplina" <[EMAIL PROTECTED]> 3/15/01 9:51:53 AM >>>
I think the trick part of question here is that the answer d.
172.16.80.255 
seems like a broadcast address because of the 255 (all 1's in the last

octec.) So now the test taker faces the dilemna of choosing between
two

subnetwork addressess and two "broadcast" addresses.

Cisco would want to know if you really know subnetting. Hence, the
wording 
of the question (which to my opinion is still correct).

ouch!  Please do not attempt this at home.  Heck, please do not attempt

The binary mask for last octet would be 1010. If you assume the use
of subnet zero, your host address go from 1 to 31, then skip to 64-94.
The next subnet in binary is 0010 so the network address is
192.10.3.32 and host address are 33-63 and 95-126.  This is painful,
it's making my head hurt

Okay then, the next subnet in binary is 1000, or .128 in decimal,
and your host addresses are 129-159 and 192-223.  The final subnet is
1010, or .148 and the host addresses are 149-180 and 224-254.

I think.  That is really painful to think through and I was interrupted
multiple times while trying to write this.  Please forgive me if these

Re: How to check the real rate of the frame relay circuit?

I disagree, at least based on my last experiences at this.  CIR can
sometimes but not always be shown.   Not sure if it is a function of IOS,
telco, LMI type or what, but this is not always true.

Yep. You can also have a pool of IPs on a different subnet and a separate

I think that Howard would say that it was a 2-bit mask  :)

Oops!  I knew I should have learned how to add at some point in my life!

I'm glad you caught that.  The calculations I made were bad enough as
it was with two mask bits.  I'm not going to do it again with three!

RE: Sample CCNA test question..bogus?

[Bob Vance]

"D" is the only possible answer to give on a test, since it's pretty
clear what the tester meant :)

I guess the question could have been worded:

  "Given the Class B network 172.16.0.0, using a prefix length
   of 19, which of the following is a valid address?
  "

Or much more simply and clearly:

Q. Which one of the following is a valid host address?

a. 172.16.32.0 /19

b. 172.16.64.0 /19

c. 172.16.63.255 /19

d. 172.16.80.255 /19

Re: ISP related question

[Howard C. Berkowitz]

>I know, but that will take a multination company many years to do that.
>Yes, we do not have DHCP.


A multinational company should look at the costs of not having an 
aggressive program of introducing mechanisms that make it easy to 
renumber.  Also, in an Internet economy, any organization that takes 
years to do anything has the future prospects of a brontosaurus.

Consider a scenario such as your ISPs being audited to see that they 
are assigning address space efficiently.  In the process of the 
audit, the address registry learns that you have a registered /16 
that you are not advertising, but want more registered space from 
your providers' allocations.

As address space becomes more tight, I can picture the ISPs being 
told they can't consider your requirements as part of their address 
justification.  Not necessarily a likely scenario today, but not 
beyond the bounds of plausibility.

I apologize if I'm seeming sharp, which might be due either to my 
broken ankle or the drugs I'm taking for it. But I get very, very 
tired of companies that want to play in the public Internet, but find 
it too inconvenient to be good Internet citizens with respect to 
address utilization and impact on global routing. Don't get me wrong; 
some very large networking companies are in this category.  Doesn't 
make me less tired of it.

Don't even begin to get me started on new.net.

Re: Certification Zone

Since the technical director of that website--as well as a few
contributors--are members of the list you'll probably receive a lot of
positive replies.

What was the nature of the discussion you had with Cindy/Jenny?  I'm
sure if you provide more details that would facilitate any corrective
action that might need to be taken.

Personally, I have heard nothing but wonderful words about the site. 
In fact, I plan on subscribing soon.  I have the highest respect for
Howard and the others from the list who have contributed and I'm anxious
to get some more study material.

Regards,
John

Re: Certification Zone

[Tom Lisa]

John,

I can't address your experience with one of their employees, however my experiance has
always been positive.  Just the fact that Howard is associated with them and often
provides tutorials, white papers and practice exams is enough to make them worthwhile.
They also have a wealth of material from many of the "well-known" experts in our field.

Everyone I have dealt with has always responded to me quickly and politely.  They have
even allowed me permission to use some of their material (Howard's of course) in my
classroom without charge.

I am a subscriber and I recommend them to my students as well.  Perhaps the person you
were dealing with was just having a bad day.

Router getting DDP

[Hingchuen Chan]

Hey guys,

I've read a section about exchanging DDP from McGraw-Hill's BSCN but I'm not 
sure whether I interpreted right or not. This is my understanding.

After a router received information about its neighbours, it will try to get 
information to establish its link state database. So, it will establish an 
adjacency with another router. The router with the highest router ID will 
become the master and it will send information to the slave. If the slave 
believes that it is still missing information, it will send out link state 
request packets to get informations it needs.

Now here's the question, what happens if the new router (ie just came onto 
the network) has the highest router ID? It will send information to other 
routers but it won't know that itself is lacking routes since it just came 
on. Therefore, it will not send link state request packets. Is that right?

Thanks in advance
