Group,

 

I'm planning on purchasing my final addition to my RS home lab sometime
this month. I'm having a hard time deciding if I should add another 3550
(I have one already) or if I should pick up a Lightstream 1010 with two
4500s that have an OC3 MM interface. ATM for the 3600s is way too
expensive for me. Any suggestions would be appreciated.

 

(Sorry if this message is a dub)

New Cisco Catalyst QoS book [7:75229]

2003-09-11 Thread Muhtari Adanan

Hi,

I was wondering whether it's worth reading the new Cisco Catalyst QoS IOS
book whilst revising for the CCIE theory or even perhaps the practical exams.

Release Notes for Catalyst 4500 Series Software Release 8.x
OL-4502-02
ROMMON Requirements
If the Boot ROM (ROMMON) loaded onto your switch is version 4.5(1) or
earlier, you need to upgrade
the ROMMON to at least version 5.4(1) in order to run software release 8.1
or later.
Upgrading the ROMMON
Follow these guidelines to upgrade the ROMMON on your switch:
3
Release Notes for Catalyst 4500 Series Software Release 8.x
OL-4502-02
System Requirements
Caution To avoid actions that might make your system unbootable, read this
entire section before starting the
upgrade.
You can do this procedure entirely over a Telnet connection, but if
something fails, you will need to have
access to the console serial port. If done improperly, the system can become
unbootable. You will then
have to return it to Cisco for repair.
This section describes an upgrade to ROMMON version 6.4(1). The same
procedure applies to other
ROMMON versions, but you will have to substitute appropriate version numbers
in the upgrade image
names.
Step 1 Download the promupgrade program from Cisco.com and place it on a
TFTP server in a directory that
is accessible from the switch to be upgraded.
The promupgrade programs are available at the same location on Cisco.com
where you download
Catalyst 4500 series system images.
To upgrade to ROMMON version 6.1(4), download the
cat4000-promupgrade.6-1-4.bin file.
Step 2 In privileged mode on your switch, use the show version command to
verify the ROMMON version
loaded on the switch.
The ROMMON version number is listed as the System Bootstrap Version. For
example, in the following
output, the system is running ROMMON version 6.1(2):
Console (enable) show version

Hi all,
  I wonder if any of you have succesfully retrieved the BGP table from a
Cisco router using SNMP?. I read a lot of documents and tried a lot of
MIBs/OID without any success. I used the MIB navigation tool at the Cisco
TAC but I did not find something really useful. I only could read the
peerings, uptime of the BGP session and few more thing. By the moment I
think it should be done using snmpwalk, am I right?
  FYI, I do have the full routing table in one of my routers (IOS 12.2.6)

Any help will be appreciated.

RE: router CPU utilization on access lists? [7:75002]

 Yes, that's true indeed that access lists don't cause process switching
 anymore, so wouldn't show up in IP Input.
 
Two exceptions that I failed to mention are logging and the side effect
of a deny.  By default, a deny causes the generation of an ICMP admin.
prohibited unreachable sent to the source of the blcoked packet.  Since
packets cannot be created in interrupt mode, process context is required.
But these are rate limited to two/second by default as self protection.
Plus normal traffic shouldn't result in very many denies.  But you can
inhibit this entirely by configuring no ip unreachables on an interface.

If the matching ACE has the log keyword, then process context is required
to create the log message and perform normal logging.  This too is
rate-limited.

 Thanks for everyone's advice. It sounds like Marty has the right approach.
 Although access lists aren't process switched, they are generally fast
 switched unless the router supports some other feature (like silicon
 switching) or some fancy configuration like CEF or NetFlow?
 
 So, the thing to look for is a high utilization caused by interrupts (the
 number after the slash).
 
 I can't safely turn them off and test, so I think I will try to simulate
the
 network and traffic in a lab to test my theory that they are an issue.
 
 It's a 2621 router with lots of entries in the access lists that are
 applied. I think it's time to offload a lot of the policy represented by
the
 lists to a PIX firewall.
 
You can tune the lists by letting it run for a while and then noting the
match counts (show access-list).  Within each grouping of permit entries,
you
can reorder the statements to reduce the number of entries that must be
compared to reach a match.

If the ACL processing is as efficient as possible but is really impacting
CPU
utilization, then you could enable the turbo ACL feature (access-list
compiled).
Unfortunately, that's still only available on higher-end platforms, from
3700s
on up.

 Here's a good URL on troubleshooting high CPU util, by the way:

Ethernet bogs down help has anyone seen this problem [7:75238]

I have a customer that has a small office with a Cisco 56K Frame router.
They
are running Nat. Now when I plug in the frame side the ethernet side gets 
constant request for translation then it gets to the point where you can no 
longer even ping the ethernet side. If I remove the RG45 cable from the
frame side.
No problem the request stop and I can ping my ethernet side of the router 
fine with 10ml sec responses all day. The users office is down because he
can not
get out to the web. I've checked for viruses and everything seems fine. Does 
anyone have any ideas? This one is driving me crazy. The ISP says that my 
router is bad, but I doubt it. It started all of a sudden after working fine
for 2
years.

Re: Difference between Cisco VPN and PIX Firewall [7:75235]

2003-09-11 Thread annlee

Stnadard answer: it depends.

Followed immediately by the standard question: what problem are you
trying to solve?

The VPN Concentrator does not firewall or filter; it is a specialized
tunnel termination device. You may (emphasis on may) need to use it
when you are terminating more than about 20 tunnels. That depends on
how active the tunnels are and what else your firewall is doing -- how
much other work must it do filtering how much other traffic?

The Concentrator does offer AES and DH Group 7 (the latter is useful
if the other end of the tunnel is a client which can support ECC, but
not many can).

You need a firewall between you and the Internet. Have a look at the
SMR SAFE Blueprint, here:
http://www.cisco.com/en/US/netsol/ns110/ns170/ns171/ns128/networking_solutions_white_paper09186a008009c8a0.shtml

If you do decide to use a Concentrator, people may differ, but I
recommend terminating your tunnels outside the firewall. If you don't,
the firewall must either work at the traffic to inspect it properly
(which in fact makes it work even harder tore-encrypt, etc. to send it
to the Concentrator) or you poke a big hole in the firewall by
accepting traffic that looks like it ought to be a part of the
tunnel. If your LAN receives public traffic (is there a public-facing
server, any kind of mini-DMZ?), then you will want a switch to send
tunnel traffic tothe Concentrator and all other traffic to the
firewall. Looks sort of like this:

Concentrator
/ \
Internet---switch/\firewall---LAN

RE: Difference between Cisco VPN and PIX Firewall [7:75235]

Scenario III is probably the most recommended.  It is incorrect to say that
the VPN Concentrator does not have filtering capabilities.  It generally
only allows traffic in its public interface necessary for VPN connections,
so it is not any more inherently insecure as a PIX.  It does not have all of
the capabilities of the PIX however, so if you need a true firewall I'd go
with a firewall (not necessarily a PIX, I personally think they suck, go
with a Check Point).

RE: ciscoview-urgent [7:75227]

If you happen to be running PIM Sparse-Dense mode with auto-RP and
duplicate loopback IP addresses then you need a special patch for
CiscoWorks in order for it to properly discover the 6509's...  This probably
effects anything that has duplicate loopback IP addresses.

RE: help [7:75225]

Oops!  I am moving the mailing list users to a new server and was testing
the new server.  I inadvertently sent one of the test messages to the active
list.  At 3:00 AM when stuff is not working, yelling help does not seem
like a bad idea :-).

By the way, the move should be done by this afternoon.  Unless I get tied up
with something else, you will receive a welcome message (those that read via

Take care,

RE: NAT and SAP [7:74982]

Different approach:
Howmany clients? Static Nat on the router the other way around?

Give the server a route pointer to the nat router for the client. 

You even can choose to give the client a global ip to connect to the server
with, like a mail server for example.

When a SAP client tries to connect to a SAP server through a router with NAT
enabled there is a problem: the SAP server sends an IP embedded on the
payload of the packet, and the NAT router do not translate it.

Any suggestion?

think it's a NAT problem, some show commands for NAT include:

show ip nat statistics
show ip nat translations

You say the problem just started all of a sudden? The Internet has been
pretty shaky lately. You may be getting pinged constantly, for example. Are
you stopping those before you translate them? Do you have a firewall? Is the
router acting as a firewall? How is it configured? Please send us more data

 Just practice and play with the BITS in the MASK.. You can achieve this

2003-09-11 Thread Bob by The Bay

Yongwee,
!
!  Deny even numbers but permit everything else
!
access-list 101 deny tcp 192.168.2.0 0.0.0.254 host 192.168.1.254 eq telnet
access-list 101 permit any any
! implicit deny all here

or perhaps more efficiently
!

!  Permit odd numbers only
!
access-list 101 permit tcp 192.168.2.1 0.0.0.254 host 192.168.1.254 eq
telnet
! implicit deny all here
!
These answers are based on the fact that an even number in binary will have
a least significant digit of 0 in the octet while an odd number will have a
1.  Thus the 0.0.0.254 mask isolates the least significant digit for a match
against either a 1 or a zero.

FWIW,
Bob

RE: ciscoview-urgent [7:75227]

Communications problem.  I don't understand what you are asking.  Try using
more words.  Be verbose.  I may be able to understand then...

As far as I can tell:
You are not having any problems discovering the 6509.  It is in the
topology.  In your original messages, you said you were NOT getting the 6509
in the topology.  See my confusion?

Beyond that, I don't know what your problem is, so I can't suggest a
solution.

Just an off-the-wall guess, you probably need to load up the latest device
information file (Incremental Device thingy) in CiscoWorks to recognize a
particular module that may have been released recently...

Cisco has a messed up way of implementing the L2TPv3 tunnels like this. 
Basically you looped two FE ports together.  Pick 1 port for your layer 3
routing and the other port to cross connect your layer two tunnels.  The
vlan ID for the two FE ports must match.  The tunnels reference the loopback
of the endpoint router.  Hope this helps.

RE: Network Benchmarking/Performance Analysis [7:74808]

2003-09-11 Thread Loechel, Michelle

For the SAAgents embedded in the IOS, use the IPM (Internetwork Performance
Monitor) software.  It comes as part of the CiscoWorks package.  I don't
know if you can buy it as a standalone package.  It includes a plug-in to
CiscoWorks and a client to install on the pc.  It's much easier to configure
and view statistics through the GUI.

VitalNet from Lucent Technologies can use Cisco SAA, so in a way it's
distributed polling.  Any (recent) IOS device would become a sensor/collector.

You would have to do each host individually as:

access-list 110 deny tcp host 192.168.2.2 host 192.168.1.254 eq 23

You cannot choose only even addresses with any kind of command. Atleast not

  I install ciscoworks. I have GSR,7513,6509,3512 in

7513,3512,and GSR.

   I install CATIOS6000,Switchaddlets,Entity,

 As far as I can tell:
 You are not having any problems discovering the
 6509.  It is in the
 topology.  In your original messages, you said you
 were NOT getting the 6509
 in the topology.  See my confusion?
 
 Beyond that, I don't know what your problem is, so I
 can't suggest a
 solution.
 
 Just an off-the-wall guess, you probably need to
 load up the latest device
 information file (Incremental Device thingy) in
 CiscoWorks to recognize a
 particular module that may have been released

SAP, SAP, what the heck is SAP?  At first I thought it was SIP, but that
doesn't sound right.  Maybe it's referring to the COMPANY SAP?  If so, what
specific application are you talking about?

I must say SAP's website is a nightmare.  Looks like all marketing speak to

Different approach:
Howmany clients? Static Nat on the router the other way around?

Give the server a route pointer to the nat router for the client. 

You even can choose to give the client a global ip to connect to the server
with, like a mail server for example.

Onderwerp: NAT and SAP [7:74982]


When a SAP client tries to connect to a SAP server through a router with NAT
enabled there is a problem: the SAP server sends an IP embedded on the
payload of the packet, and the NAT router do not translate it.

Any suggestion?

Mailing list conversion we are moving .... [7:75275]

If you are subscribed to this list via e-mail, we will be transitioning to a
new server with new software.  Within the next few hours you will receive a
welcome message from the new server.Please save this e-mail as it
contains your password and subscription instructions.

If you never receive the welcome message, and you are receiving this list
via e-mail, please send me an e-mail.  If you are not receiving messages
from the new server once the transition is complete, again please report it.
In both cases, before you report it, please make sure it is not a problem on
your end (i.e. your anti-spam filters etc.).

The upgrade should take care of a number of problems including the time
required to distribute mail and various digest options.

Also, do not forget about our online meeting -- 8:00 PM at
Chat.GroupStudy.com!

Take care,

Paul Borghese

RE: ciscoview-urgent [7:75227]

I still don't know what you mean by ? is coming on that box  Do you mean
for the OSM module?  That's not listed in the supported devices for Campus
Manager (which I'm assuming you mean by the topology view.

You might try asking at [EMAIL PROTECTED]  They have many more
CiscoWorks people over there.  I'll cross-post...

 As far as I can tell:
 You are not having any problems discovering the
 6509.  It is in the
 topology.  In your original messages, you said you
 were NOT getting the 6509
 in the topology.  See my confusion?
 
 Beyond that, I don't know what your problem is, so I

 Just an off-the-wall guess, you probably need to
 load up the latest device
 information file (Incremental Device thingy) in
 CiscoWorks to recognize a
 particular module that may have been released
 recently...

 [7:75238]

 I have a customer that has a small office with a Cisco 56K
 Frame router.
 They
 are running Nat. Now when I plug in the frame side the 
 ethernet side gets 
 constant request for translation then it gets to the point 
 where you can no 
 longer even ping the ethernet side. If I remove the RG45 
 cable from the
 frame side.
 No problem the request stop and I can ping my ethernet side 
 of the router 
 fine with 10ml sec responses all day. The users office is 
 down because he
 can not
 get out to the web. I've checked for viruses and everything 
 seems fine. Does 
 anyone have any ideas? This one is driving me crazy. The ISP 
 says that my 
 router is bad, but I doubt it. It started all of a sudden 
 after working fine
 for 2
 years.

RE: question on acl [7:75257]

Er, yes you can.  Two people have already replied on how.  Use a WILDCARD
mask of 0.0.0.254.  Simple, easy, effective.  I'd hate to have to type in
128 permit statements.  Probably end up writing a Perl one-liner, but the
easier way is to use the proper WILDCARD mask.

RE: NAT and SAP [7:74982]

Different approach:
Howmany clients? Static Nat on the router the other way around?

Give the server a route pointer to the nat router for the client. 

You even can choose to give the client a global ip to connect to the server
with, like a mail server for example.

RE: help [7:75225]

Oops!  I am moving the mailing list users to a new server and was testing
the new server.  I inadvertently sent one of the test messages to the active
list.  At 3:00 AM when stuff is not working, yelling help does not seem
like a bad idea :-).

By the way, the move should be done by this afternoon.  Unless I get tied up
with something else, you will receive a welcome message (those that read via
e-mail) describing the new server.

Take care,

Paul

Fred,

The ? in the icon on the Topology map means it's an unknown device.
It knows it's CDP supported but it can not identify it's Cisco Device ID or
the sysObjectID.  There are a couple of reasons for this including the fact
they are in reality HP JetDirects, New HP Servers (they both support CDP )
or the device or OS version is not supported by the version CW2K he has.

Subject: Ethernet bogs down help has anyone seen this problem
[7:75238]


I have a customer that has a small office with a Cisco 56K
Frame router.
They
are running Nat. Now when I plug in the frame side the 
ethernet side gets 
constant request for translation then it gets to the point 
where you can no 
longer even ping the ethernet side. If I remove the RG45 
cable from the
frame side.
No problem the request stop and I can ping my ethernet side 
of the router 
fine with 10ml sec responses all day. The users office is 
down because he
can not
get out to the web. I've checked for viruses and everything 
seems fine. Does 
anyone have any ideas? This one is driving me crazy. The ISP 
says that my 
router is bad, but I doubt it. It started all of a sudden 
after working fine
for 2
years.

Onderwerp: EM VoIP Problem [7:74717]


Dear Experts,

I am having this problem with EM VoIP.  We are using an EM PABX operating
with 4 wire and using immediate signalling.  The network are connected via 2
Mbps Leased Line.  I can make voice calls from my site to remote site,
however when i asked someone from the remote site to call the other way
around he get busy tones all the time eventough the extension were actually
not bust at that time.

The strange thing is that the remote site can make voice call to my site
only to 2 extension (300 and 400),  but when they dial another extension ex:
363, or 369 they get busy tones all the time.

the dial-peer configuration on the remote router are like this

dial-peer voice 1 pots
destination-pattern +...
port 1/0/0

dial-peer voice 1 pots
destination-pattern +...
port 1/0/1

dial-peer voice 3 voip
destination-pattern +3..
session target ipv4:172.23.1.34(ip address of router's serial interface at
my site).


dial-peer voice 4 voip
destination-pattern +4..
session target ipv4:172.23.1.34 (ip address of router's serial interface at
my site).

Is it the wiring arrangement problem?
i already set up the wiring arrangement based on a reference i got from CCO.

Is it a timeouts parameter problem?

or Is it the EM PABX problem?

Like always, the PABX technician feel that he has done everything correctly.

I am also confident that i have done the configuration correctly.

Anyone has similar experience?

Any idea would be greaty appreciated.

Thanks in advance.

Basic IP CEF question (again) [7:75161]

2003-09-10 Thread Curious

The history:

Author: Zsombor Papp (---.dsl.snfc21.pacbell.net)
Date:   09-08-03 14:47

It means that's the router's own IP address. 

Thanks,

 Hello dear friends, 
 I would like to know the meaning of the keyword receive that I

 For example:

 10.64.15.224/32 receive 
 
 What means that the next-hop is receive. 
 
 More details: 
 
 ROUTER#sh ip route 10.64.15.224 
 Routing entry for 10.64.15.224/28

 Route metric is 0, traffic share count is 1 
 
 Any comments?? Bye and Thx 
 
 

My comments:

Hello Zsombor, I can see IP addresses that doesn't belong to the router, for
example:
Router#sh ip cef | include 10.224.0.51
10.224.0.51/32  receive

But the IP address of the router in the subnet is:

 10.224.0.49

The subnet is:

 10.224.0.48/30

So the IP address 10.224.0.51 is the broadcast address of the 
router in the network, but not the IP owned by the router.
What do you think??
Thx a lot.

Re: PIX PDM [7:74758]

2003-09-10 Thread Philip Suen

I have experienced by using PDM to configure VPN is unstable. Everytime I
try to modify the particular VPN connection. All of the connection will be
disconnected.

In addition, everytime if you have changed the configuration in PDM, you
must remember to save it manually, otherwise reboot will erase all of the
config.

Finally, before you make any change within PDM, you should download the
latest version configuration from PIX. Otherwise, you will erase the running
config.

RE: Please Help - CIDR - How the bits work [7:75050]

No offense, but this is CCNA material.  If you are going for your CCNP, then
you should already have your CCNA and know the answer.  But anyway...

If you need a network with 400 hosts, the smallest subnet would have a /23
mask.  So take the first part of your given network and assign it to that:

192.168.24.0/23 (192.168.24.0-192.168.25.255)

Then you need one with 200 hosts.  Well, that could fit within a /24 subnet,
so assign the next available to that:

192.168.26.0/24 (192.168.26.0-192.168.26.255)

Now you only have 192.168.27.0/24 left from the original 192.168.24.0/23
(which covered 192.168.24.0-192.168.27.255).  You need two 50's, so that
should fit within /26 subnets each.  Assign them:

192.168.27.0/26 (192.168.27.0-192.168.27.63)
192.168.27.64/26 (192.168.27.64-192.168.27.191)

Finally, you need three subnets that can have two hosts each, which would
fit within /30 subnets.  So assign:

192.168.27.192/30
192.168.27.196/30
192.168.27.200/30

When fingerpointing in quite a number of external connectivity

Cisco hardly helps this by discriminating against static and default

 May be I had advanced access to the new NA material then ;-)  In my view, a
 NA should be able to handle basic RIP, OSPF, EIGRP in a small to medium

 advanced RIP, OSPF, EIGRP, and basic BGP, like for configuring a mid-large
 sized network for connection to the Internet including minimal BGP.  IE,
 IMO, is for ISP engineers that have to deal with extensive IS-IS, BGP using
 all options, etc, and large to huge (global) networks.
 
 May be I'm just expecting too much, but if you don't understand CIDR you
 shouldn't be allowed anywhere near a router, let alone be responsible for

Looking at your specific problem - think in powers of two. 400 nodes is
greater than 256 but less than 512. Use /23 out of your allocation. 200 is
less than 256 so use a /24.
50 is greater than 32 and less than 64 so use a /26 for each. The serial

RE: Please Help - CIDR - How the bits work What I figured out [7:75173]

From what you say, I think you have it, but I'm not sure.  Starting from the
bottom of a /24 subnet (Class C), you could have a /26 subnet, then two /27
subnets, then four /28 subnets, and finally another /26 subnet.  Or you
could have two /28 subnets, one /27 subnet, one /26 subnet, followed by a
/25 subnet.  The combination, and order, does not really matter, as long as
no IP addresses within the subnets overlap.

For instance, you couldn't have a /26 (64 addresses) followed by a /25 (128
addresses), followed by a /26 (64 addresses).  Why?  Because there can't be
any overlaps.  The 64 would start at .0 and go to .63.  The 128 would
start...  Where?  It can't start at .64, because that's in the middle of say
192.168.24.0/25 (which is 192.168.24.0-192.168.24.127).  It would need to
start at .0 or .128.  If it started at .128 then it would extend to .255, in
which case there wouldn't be room for the last /26 subnet.  So, you re-order
them and use either a /26, /26, and /25, or /25, /26, and /26.

Remember, the whole classful/classless thing is routing protocol specific.
It has nothing to do with how hosts view IP addresses, or make routing
decisions (meaning whether to send it to a router or if the address is
local).  The source code for a TCP/IP stack may look something like this:

# Assuming addresses/masks are 32-bit numbers, not dotted decimal
# string representations of addresses/masks.

# $ip_src is the IP address of the outgoing interface on the host
# $ip_dst is the IP address of the destination
# $ip_mask is the subnet mask on the outgoing interface
# $ip_gateway is the IP address of the default gateway

# check to see if destination address is in same subnet as our interface
if (($ip_src  $ip_mask) == ($ip_dst  $ip_mask)) {
# send directly to destination, possibly arping out first
} else {
# send to default gateway, $ip_gateway,
# possibly arping out first
}

There would obviously be more logic in there as you may have more than one
route and not a single default gateway, but the important point is that it
does not matter about the classfulness or classlessness of the subnet
mask.  The host doesn't give a hoot.  As long as the source and the
destination both agree whether they are in the same subnet or not everything
works fine.  If they don't, you may need some ancient hack like proxy ARP,
but I don't know anyone in their right mind that would recommend
purposefully MIS-configuring a network so that it is required.

I was stuck on the idea that you could ONLY re subnet a remaining piece 
of a subnetwork.  And not apply a mask to the whole span of the total 
available network.  You can (unless I'm incorrect here) you just have to 
watch out for address over lap neer your subnetwork boundries.

 Do they still teach classful for CCNA, though? Perhaps the only thing

If you are going for
your CCNP, then
you should already have your CCNA and know the answer.  But
anyway...

If you need a network with 400 hosts, the smallest subnet would
have a /23
mask.  So take the first part of your given network and assign
it to that:

192.168.24.0/23 (192.168.24.0-192.168.25.255)

Then you need one with 200 hosts.  Well, that could fit within
a /24 subnet,
so assign the next available to that:

192.168.26.0/24 (192.168.26.0-192.168.26.255)

Now you only have 192.168.27.0/24 left from the original
192.168.24.0/23
(which covered 192.168.24.0-192.168.27.255).  You need two
50's, so that
should fit within /26 subnets each.  Assign them:

192.168.27.0/26 (192.168.27.0-192.168.27.63)
192.168.27.64/26 (192.168.27.64-192.168.27.191)

Finally, you need three subnets that can have two hosts each,
which would
fit within /30 subnets.  So assign:

Re: Please Help - CIDR - How the bits work [7:75050]

2003-09-10 Thread annlee

I get the same results as Marko, but this may lay it out so you (and 
others) can see the development:

IP address = 32 bits
Network portion = 22 bits
Host portion = 10 bits
Total addresses for host portion = 2^10 = 1024

Start with 192.168.24.0/22
Focus on the 3rd octet (network_host): 000110_00

400 hosts requires 9 bits (2^8 = 256, 2^9 = 512)
and you will have some left in this block
divide the /22 into two blocks of 512 addresses each:
0001100_0 (.24/23) and 000_0 (.26/23)
use .24/23 for the 400-host network

200 hosts requires 8 bits (2^7 = 128, 2^8 = 256)
and there will be some left in this block, too
divide the .26/25 into 2 blocks of 256 addresses each:
0000 (.26/24) and 0001 (.27/24)
use .26/24 for the 200-host network

50 hosts requires 6 bits (2^5 = 32, 2^6 = 64)
and you will again have some leftovers
divide the .27/24 into 4 blocks of 64 addresses each
now looking at the 4th octet:
00_00 (.0/26), 01_00 (.64/26), 10_00 (.128/26), and 
11_00 (.192/26)
use the first two for the 50-host networks

and the rest is easy

My personal rule is to always start with the biggest blocks and work 
down from there.

Re: Frame Relay Switch [7:75019]

Hi, guys:

Why not consider 2523 i/o 2522 ?

In the hardware spec, Cisco 2523 is the same as 2522, all the difference is
2523 is Token-Ring based,
In eBay, you could find out that R2523 is cheaper than R2522,
For the cost issues, I would suggest the 2523.

If the cost/price is not the issues, maybe you could consider 4500/4700M+
with NP-4Ts,
4500/4700 has more horsepower than 2522/2523...

ATM switch configuration. [7:75137]

2003-09-10 Thread Rajesh Kumar

Hi all,

Can somebody point me to the location where I can copy paste the base 
ATM switch configuration to be used in the labs like Ipexpert?  Since I 
am not as familiar as FR switch, all I need is to have very basic 
connectivity from ATM router having 1 or 2 PVCs.

Thanks,
Rajesh

RE: Please Help - CIDR - How the bits work [7:75050]

No reason to be sorry!  I'm all for vigorous discussion ;-)

No BGP in the NA because we are talking about SMALL to medium business.
Yes, they should know about how to connect up to the Internet, using a
default route, etc.  But you are not going to find that many ISPs, if any,
that are willing to setup a BGP peer with a store-front business with a 16
address space public network (or even granted they are given a /24 public
subnet).  If you find any, let me know!

That's why I say EGP for NP.  A medium to large business certainly may need
EGP expertise.

And I suppose that's a slight difference in the way people think about the
different certification levels.  When I say RIP, IGRP, EIGRP, OSPF should be
requirements for a NA I mean the candidates should be }experts{ in those
protocols.  Not just having a passing understanding, have read about it in a
book once, or used some study guide to rote-memorize answers to common
questions.

So, on the one hand I think the standards should be tougher, requiring
expert level knowledge for the IGP's, and on the other I don't think a NA
needs to know anything about EGP's.

RE: IPSEC with STATIC NAT [7:74971]

Perhaps there is some confusion.  NAT Traversal is required if there is any
NAT in between the endpoints of the IPsec connection.  It has nothing to do
with NAT of devices behind a router that has IPsec configured.  Or maybe I'm
mis-interpreting.  If so, correct me!

 Hey There
 
 I am working on a solution for IPsec using vpn concentrator and VPN
hardware
 clients(PIX). The PIX outside has a public address and the only NAT taking
 place is at the edge router and the vpn concentrator sits behind this
 router. The router does a static public-to-private IP nat and i dont think
I
 would need NAT traversal since it's not changing any ports..only changing
 IP's.
 
 Please let me know if there is anything I would need to do on the edge
 router doing the static NAT. I've heard that for STATIC nat to work with
 IPSEC, you need to adhere to certain standards.
 
 Thx to everybody in advance.

and has been the netire time I have been playing at certification. But
in general, I believe the idea is that CCxA is beginner, CCxP is
intermediate, and CCIE is high level.

as with all things certification related, YMMV. I've known CCNA's who
manage large networks, and I've known CCIE's whose knowledge of certain
specific areas was less than expert. As can be expected, depending on

When fingerpointing in quite a number of external connectivity 
problems, I have often found de fault is due to the lack of default. 
Cisco hardly helps this by discriminating against static and default 
routes in the CCIE lab.

That is correct.  Or at least it can only support one VLAN in common with
the Cisco gear.  It can have all the VLANs it wants as long as it does not
have dual links to the Cisco gear, creating a loop which will not be blocked
with Spanning Tree, because it doesn't support PVST+.

BTW - what are Hwa Wei switches?

F800 and still mean the same thing.  You obviously can't do that with
255.255.128.0 (255.255.128.0 != 2,552,551,280).  While binary works the same
way as hex in this manner, it is much to long for my tastes.  Plus, hex is
used a lot in programming languages when using values in bitmasks, so I'm
more familiar with it.  Also, there are only 5 hex numbers that you need to
memorize for masks, F 0 8 C and E.

Seriously, I've fought a battle for many years with Cisco Training. I 
believe the fundamental problem they _create_ is insisting on 
teaching classful and dotted decimal notation first.

When I've given private classes -- ICRC, the older RSC, etc. -- I 
always began discussing addressing in binary, got people used to the 
idea of prefix length, then introduced dotted decimal as a means of 
representation, and then introduced classful addressing as a historic 
concept.  Students were always able to go right into classless 
routing without any trouble.

There are some nice examples in RFC 1878.  RFCs 1517-1520 give the 
main background, although there are some earlier papers on 
supernetting.

With all mercenary disclaimers, I also recommend my book, _Designing 
Addressing Architectures for Routing and Switching_, and my recent 
IPv4/IPv6 tutorial on Certification Zone.
