CCIE Written

[Jason]

Just passed my CCIE written a couple of days ago. Passing score was 70% !! I
was expecting 65% . Anyway, it's not that bad if you know your stuffs.
Basically a combination of ACRC and CIT. And yes, I read very carefully ,
the wordings of the Survey does say that how you answer will determine the
passing score !!

Took it in New Horizon in Walnut Creek. I had a SMALL 14 inch monitor which
makes things difficult. The system also crash on me twice. First time, I
waited in the room for 15 mins and 2nd time, I just walk out and sit outside
and wait. Maybe that took the pressure off me a tiny little bit the 2nd
time.  Will schedule the lab soon. Any advise, suggestions as to the testing
center ?

Re: Technical Question

[harora]

To have 2 NICs in a machine, it is not necessary to have a WINNT
workstation. You can install 2 NICs on Win95 also. I have done it myself.
But the IP addresses for both the NICs should not have the same network.
Already you are having 2 n/ws so there is no issue in installing 2 NICs.

Hopw this helps
Cordially

Subject:  Technical Question





I need some technical advice. We connect customers to our internet service
over 100 Mbs Ethernet. We assign the customer private IP addresses which
our
router translates to a public IP. We configure the customer PC's with these
private IP addresses. This one particular customer has one PC that accesses
a Lotus Notes Server in NY over a point-to-point frame relay connection.
This connection is provided by AT&T and they have a router attached to the
customers Ethernet hub whichserves as the gateway to this service. The
router has an IP address of 32.82.221.33  mask 255.255.255.240 and the IP
address of the one PC that accesses it is 32.82.221.37 mask
255.255.255.240.
Our router is also attached to their Ethernet hub but it has an IP address
of 172.16.228.1 mask 255.255.255.0. The customer wants this PC to access
both routers. If we change the IP address to be in our network it wont be
able to communicate with AT&T's router. I considered using two network
cards
in the PC, one with the AT&T IP address and one with ours. I would have to
install NT Workstation to make the PC support two network cards. First,
will
that work and Second, is there another solution besides changing IP
addresses of the routers.

Any help would be appreciated.

How would you configure a Cisco router with two serial

I have have already done some tests using the router as

IP Summary

[Gert Jan]

All,

How many class C addresses can be summarized with 172.92.172.20/20?

Is 16 the correct answers? Because there's 4 bit's left for host addresses?
2 powered by 4 is 16.

Can one of you confirm this.

Thanks a lot.

EIGRP and OSPF

[Radford Dion]

Has anyone out there ever integrated OSPF and EIGRP?

We have a requirement where we want to take a part of our network out of the
OSPF area and make it into an EIGRP network. (Good reasons for this, I can
assure you)


Network A - OSPFNetwork B - EIGRP
172.28.0.0
172.19.0.0  172.19.49-56.0
172.19.50.1
 
X--X
---X
Router ASerial Line Router B
Router C



What I have tried
Router A: Static routes for subnetwork B pointing to Router B,
redistributing the static routes into OSPF and making the serial interface
passive. 
Router B: Static route 0.0.0.0 pointing to Router A, redistribute static
routes in EIGRP and making serial interface passive.

Router A
router ospf 100
  redistribute static subents
  network 172.19.0.0 0.0.255.255 area 11
  passive-interface serial 1
  exit
!static routes into network B
ip route 172.19.48.0 255.255.240.0 172.19.159.253

Router B
router eigrp 51
 redistribute static
 network 172.19.0.0
 passive-interface serial 0
!
!default route into network A
ip route 0.0.0.0 0.0.0.0 172.19.159.252

Router C
router eigrp 51
 network 172.19.0.0
!


It didn' work.


Router C had the correct gateway of last resort, yet you couldn't get to it
from Network A (except from Router A). 

However, I could access devices on the 172.28.0.0 network from router C
(172.28.0.0 is in another OSPF area). I think it could be due to the fact
that we are using the same major network number for both OSPF and EIGRP?

If anyone has any ideas let me know. 
Thanks,

Dion

Re: Switch Limitations?

[Phil Barker]

I am presuming the late collisions are being detected
on the cat 3500 connected to the HUB ?
After checking that the cable distance between hub and
cat switch is within limits try a spare cat switch
(out of hours) in place of the hub and see if you
still get late collisions if you do then look at the
cable with a TDR etc, if not, replace hub with more
3524's. Be aware that connecting a 3rd 3524 via GBIC's
causes the formation of an Ethernet Bus between the
switches.

Regards,

Phil.

Re: EIGRP and OSPF

[John Swartz]

1.  You need to assign a default-metric or specify the metric at the end of
your redistribute commands
2.  Under EIGRP try the command 'no auto-summary'
example:
 Router A
 router ospf 100
   redistribute static subents metric 100
   network 172.19.0.0 0.0.255.255 area 11
   passive-interface serial 1
 Router B
 router eigrp 51
  no auto-summary
  redistribute static metric 1 1000 255 1 1500
  network 172.19.0.0
  passive-interface serial 0

In the ISP industry for user accounting/authentication RADIUS wins hands

RE: Switch Limitations?

[Olden Pieterse]

Hi there Felice
On the late collisions... make sure your switch port that is connected to
the hub is on half duplex and that they are the same speed .
What is on the network (devicewise ) that create your crazy protocols ? Some
IBM , AS400's that use SNA & so on . 
As long as unnecessary protocols dont bog your network down you're fine ,
but the more unneccessary stuff you remove the better (it helps when you
have to put on your troubleshooting hat )

Hope some of it helps !

RE: load balancing traffic from ISP through a firewall

So you have two links to two ISP's that you need to balance?  If so, BGP

RE: Technical Question

[Rik Guyler]

Chuck, I have added dual NICs in the same subnet with NT 4.0, so it's
possible.  I have done this with DB servers so I can have half of the
clients hit one interface and the remaining clients hit the other.  Intel,
Compaq, and probably others provide a nice little utility that allows you to
"bond" multiple NICs together so they appear to be one, but gives the
throughput of multiple connections, similar to EtherChannel on a switch.
This works great for dynamic load balancing and gives added fault-tolerance.

As for adding a second address: with NT, open the TCP/IP properties window
and click on the "Advanced" button.  This will provide a window that allows
you to do all kinds of neat stuff!

I was a bit curious about that myself. Of course I am Windows-centric.

The one thing I never did understand in the WinNT world was why one could
not have two NIC's in a server, and assign both NIC's into the same subnet.
Could be done easily in the IPX world on a Netware box.

Any thoughts?

Re: Help!: Lost passwords on a 2621,2501

[Tony Olzak]

Actually, when you do a copy start run, it only adds lines that are missing 
from your running config. It does not actually go in and change things like 
your password. This means that you can use the command at any time. I just 
did it multiple times on my home lab.

Hello group,

My weekend project is to swap out the NP-2T network processor module on my

Since I Have not done that before, I downloaded the 'Cisco 4500 Hardware

Would the group be kind enough to offer a 'Best Practice' recommendation on
how to proceed ?

Subject: EIGRP and OSPF


Has anyone out there ever integrated OSPF and EIGRP?

We have a requirement where we want to take a part of our network out of the
OSPF area and make it into an EIGRP network. (Good reasons for this, I can
assure you)


Network A - OSPFNetwork B - EIGRP
172.28.0.0
172.19.0.0  172.19.49-56.0
172.19.50.1

X--X
---X
Router ASerial Line Router B
Router C



What I have tried
Router A: Static routes for subnetwork B pointing to Router B,
redistributing the static routes into OSPF and making the serial interface
passive.
Router B: Static route 0.0.0.0 pointing to Router A, redistribute static
routes in EIGRP and making serial interface passive.

Router A
router ospf 100
  redistribute static subents
  network 172.19.0.0 0.0.255.255 area 11
  passive-interface serial 1
  exit
!static routes into network B
ip route 172.19.48.0 255.255.240.0 172.19.159.253

Router B
router eigrp 51
 redistribute static
 network 172.19.0.0
 passive-interface serial 0
!
!default route into network A
ip route 0.0.0.0 0.0.0.0 172.19.159.252

Router C
router eigrp 51
 network 172.19.0.0
!


It didn' work.


Router C had the correct gateway of last resort, yet you couldn't get to it
from Network A (except from Router A).

However, I could access devices on the 172.28.0.0 network from router C
(172.28.0.0 is in another OSPF area). I think it could be due to the fact
that we are using the same major network number for both OSPF and EIGRP?

If anyone has any ideas let me know.
Thanks,

Dion

RE: EIGRP and OSPF

[Radford Dion]

Here is a better diagram:

Net A - OSPFNet B EIGRP
172.28.0.0
172.19.0.0  172.19.49-58.0   172.19.50.1
   X-XX
RouterARouter B  Router C

I don't understand the need for the 'no auto-summary' command. I have full
connectivity within the EIGRP network and I am not redistributing eigrp into
ospf. I use the static route on Router A to avoid the redistribution.
(Although the next thing I will probably try is redistributing EIGRP into
OSPF, cos I am out of ideas).

Also, is the metric really necessary for ospf. The default metric for an E2
route is 20, and there is only one route to NetB, so the lower the metric
the bettter?

The point of these changes is to prevent Network B from knowing anything
about network A, only how to get to it.

I should also mention that I have constructed the network in a lab and
everything works great, but I can't simulate the 1000 network ospf database,
possible routing loops and convergence time.

Thanks for the help so far,

Dion

Re: Technical Question

[TKager]

Hi Bruce,

Yes. It is possible to configure 2 NICs in the same PC. You can also multinet (assign 
both IPs to the same NIC without adding another physical NIC). Keep in mind though, 
that NetBIOS will only bind to one of these logical interfaces. From the description 
of what services you are accessing, this does not seem to be an issue. You will also 
need to set up some static routes on the NT box, to ensure that the proper paths are 
taken. This may be the cleanest solution. I have done this type of scenario over NT, 
but have not tried to do this over 95/98, although I do believe it's possible.

I can also think of a more sophisticated way in which this could be handled, although 
it is probably a little over the top.
A) Configure the client with an address within your assigned network (subnet of your 
router).
B) Multinet your router (to also contain an IP within AT&Ts assigned range). 
C) configure a static route on your router to allow a path to the Notes server, via 
the AT&T router.
D) Configure address translation on your router to translate your address to an 
address within the AT&T assigned range, such as the address you multinet to the 
router's interface.

Good Luck and Have FUN!

Tom Kager

There's some coverage in CID, but I always found that it was one of 
those areas where good instructors went considerably outside the 
course notes.  I analyzed the subnet size issue in my book _Designing 
Addressing Architectures for Routing & Switching_, still with the 
caveat "it depends".  I looked at the management and processing 
aspects in my second book, _Designing Routing and Switching 
Architectures for Enterprise Networks_, and still observed "it 
depends."

Leaving inter-VLAN traffic aside for the moment, the protocol limits 
on numbers of VLANs (IIRC 1000 in ISL and somewhat more in 802.1Q 
[it's a 16 bit field but I don't remember how much is taken up for 
other things--at least 4 bits]) are highly unlikely to be the 
limiting factors.   The IOS limit on number of subinterfaces 
(traditionally 300, but increased in recent releases) is another high 
limit.

A much more likely limit is the bandwidth of trunks.  If you have 3 
Fast Ethernet VLANs that average 50% utilization, you may (not a 
given) have trouble trunking all of them over a single 100 Mbps 
trunk.

More often than not, a limitation is less the number of VLANs, but 
the number of hosts per VLANs.  This limit is highly dependent on the 
protocols used (especially how much they broadcast and multicast), 
the power and efficiency of the host OS and NIC in handling 
broadcasts and multicasts, and total traffic.

RE: Technical Question

[Dave Hennen]

one reason is because lots of things depend on netbios names in Windows
95/98/NT networking.  each computername is used as a netbios name.  each
netbios name has to be unique, so requests "I need the mac address of the
computer with netbios name whatever" can be answered by only that machine.  

if you have one server with two nics on the same network each of the nics
tries to register the computername and they fight with each other.  try
changing a windows 98 machines computername to be the same as another
machine on the same network and you'll get an error about a duplicate
computername and the second one will not be able to get on the network, same
thing.

In NT there are ways around it, look at the netbios tab under the bindings
tab for one of the nics you can disable the wins client.  I think this stops
the nic from trying to register the name.

It's better to not design something like this in the first place.  If you
want the second nic for fault tolerance, look for a solution that binds the
two nics into one logical nic and one mac address

probably someone can give a more technical explanation...

help! Automatic router config changeover

[harora]

Hi guys,

Has anyone made a setup like as follows:

The router config should automatically change as per the scheduling.
Exactly speaking, I want, that between 09:00 to 17:00 the router should
block the FTP and HTTP traffic and after 17:00, the router should not block
that. i.e. the router config should change automatically and according to
the schedule.


so the seup should be
Block FTP, HTTP only and allow all other traffic between 09:00 to 17:00
Allow all the traffic after 17:00

Any help is highly appreciated...

Cordially

Re: FW: Need BGP4 book

[vr4drvr .]

i have been informed that there is a cisco "whitepaper" on bgp somewhere in 
the recesses of cisco's site, and this document is apparently much better 
than IRA and goes into much more detail (designed for the more technical) 
and is highly recommended for the lab exam.  if anyone has any info please 
pass along...

RE: Switches and VLANs

[Matt C. Lange]

a port can belong to 2 vlans but I believe it has to be a trunk port.  You
will need a router/rsm to route between vlans.

We have 24 port switch with 3 VLANs. Can a port exist on 2 VLANs at the

Please explain how the survey determines your score? Does it make the

will I have a hard test or have to perform better?   Maybe I should just say
that not to good with my readin' words on the survey and I will get an

Just passed my CCIE written a couple of days ago. Passing score was 70% !! I
was expecting 65% . Anyway, it's not that bad if you know your stuffs.
Basically a combination of ACRC and CIT. And yes, I read very carefully ,
the wordings of the Survey does say that how you answer will determine the
passing score !!

Took it in New Horizon in Walnut Creek. I had a SMALL 14 inch monitor which
makes things difficult. The system also crash on me twice. First time, I
waited in the room for 15 mins and 2nd time, I just walk out and sit outside
and wait. Maybe that took the pressure off me a tiny little bit the 2nd
time.  Will schedule the lab soon. Any advise, suggestions as to the testing
center ?

If you buy it or other "bookstore" books from Amazon, try to use the

Subject: Re: Technical Question


Hi Bruce,

Yes. It is possible to configure 2 NICs in the same PC. You can also
multinet (assign both IPs to the same NIC without adding another physical
NIC). Keep in mind though, that NetBIOS will only bind to one of these
logical interfaces. From the description of what services you are accessing,
this does not seem to be an issue. You will also need to set up some static
routes on the NT box, to ensure that the proper paths are taken. This may be
the cleanest solution. I have done this type of scenario over NT, but have
not tried to do this over 95/98, although I do believe it's possible.

I can also think of a more sophisticated way in which this could be handled,
although it is probably a little over the top.
A) Configure the client with an address within your assigned network (subnet
of your router).
B) Multinet your router (to also contain an IP within AT&Ts assigned range).

C) configure a static route on your router to allow a path to the Notes
server, via the AT&T router.
D) Configure address translation on your router to translate your address to
an address within the AT&T assigned range, such as the address you multinet
to the router's interface.

Good Luck and Have FUN!

Would you please list the url's that you have mentioned below and also where

FW: NW Fusion launches Major Online Technical Info Exchange!

[Irwin Lazar]

FYI:
Sounds NWFusion is going after Brainbuzz.


---


How many hours a week do you, your colleagues and staff spend fixing
glitches in your enterprise network? The answer is "too many," if you're
like most network professionals we hear from.

Would a service that allows you to exchange troubleshooting information
and solutions with other corporate network professionals be valuable to
you?

Well, I'm pleased to announce that this week, in response to requests
from network professionals like yourself, we've launched just such a
valuable new service - Experts Exchange on Fusion -- on the Network
World Fusion Web site. The URL to access Experts Exchange on Fusion is
http://www.nwwsubscribe.com/nww3.asp

Experts Exchange on Fusion is the Internet's most comprehensive
information exchange forum for network professionals. With Experts
Exchange on Fusion, you, your colleagues and staff can post your
networking problems on the Internet, and those problems will be viewed
by thousands of other experts from around the world, who may just have
the solution to your problem.

When another Experts Exchange on Fusion member believes he or she has an
answer to your problem, you will be automatically notified by e-mail
that a proposed solution has been posted on Experts Exchange on Fusion.
Then, all you have to do is log in to Experts Exchange on Fusion to
review the proposed solution.

Experts Exchange on Fusion also has another great research feature:

* A searchable database that contains more than one million previously
answered questions --  so you might find your answer in a matter of
seconds.

There are dozens of network categories on Experts Exchange on Fusion to
post questions to, and search the database from, including:

*Security
*VPNs
*Firewalls
*Bugs and Alerts

*Network Operating Systems
*Windows NT
*Windows 2000
*NetWare
*Linux

*WAN services
*Frame Relay
*ASPs
*DSL,Cable modems
*Internet Service/ISPs
*VPNs

Re: Switches and VLANs

[RAUL RENTERIA]

a port can only belong to "1" vlan at "1" time.
the only time "1" port can be part of more than "1" vlan
is  when it "TRUNKS".

If you want vlan 1 to communicate to vlan 2; you need a router for vlan 
routing

Re: BSCN exam

[Edward Solomon]

>
> What are the number of question, passing score, are there lots of fill in
> questions, what do it focuse on ?

The passing score is 690 and you have 61 questions, if I remember correctly.
They are all multiple choice. You do not have to type in commands any more,
as in the ACRC test. The exam focuses on VLSM, CIDR, OSPF (single and
multi-area), E-IGRP, BGP (internal and external, plus scalability features),
route redistribution and policy-based routing.

Be familiar with the theory and configuration commands for the above topics
as they are guaranteed to turn up on the test. Know OSPF, E-IGRP and BGP
route summarisation, know how these protocols function (in detail) and make
sure that you are quite familiar with their algorithms and how they
calculate network reachability. Know BGP *thoroughly*. There are many
questions about it and you need to know how it works in great depth. Know
all the path attributes and the ways in which BGP routers communicate with
one another.

I can't stress all this enough. The exam is substantially different from
ACRC. You have to know all about how these scalable routing protocols work,
as well as how distance vector protocols function. There are the odd few
questions about those, too. BGP is probably the most significant difference
between the Routing 2.0 exam and the old ACRC test.

Subject: Technical Question



I need some technical advice. We connect customers to our internet service
over 100 Mbs Ethernet. We assign the customer private IP addresses which our
router translates to a public IP. We configure the customer PC's with these
private IP addresses. This one particular customer has one PC that accesses
a Lotus Notes Server in NY over a point-to-point frame relay connection.
This connection is provided by AT&T and they have a router attached to the
customers Ethernet hub whichserves as the gateway to this service. The
router has an IP address of 32.82.221.33  mask 255.255.255.240 and the IP
address of the one PC that accesses it is 32.82.221.37 mask 255.255.255.240.
Our router is also attached to their Ethernet hub but it has an IP address
of 172.16.228.1 mask 255.255.255.0. The customer wants this PC to access
both routers. If we change the IP address to be in our network it wont be
able to communicate with AT&T's router. I considered using two network cards
in the PC, one with the AT&T IP address and one with ours. I would have to
install NT Workstation to make the PC support two network cards. First, will
that work and Second, is there another solution besides changing IP
addresses of the routers.

Any help would be appreciated.

Unequal cost load-balancing is only available using IGRP and E-IGRP due to
the metric variance capability. OSPF has no means of allowing this as the
protocol is only able to support equal cost load-balancing, which goes by
the name of Equal Cost Multipath in the world of OSPF. Cisco also supports
this using RIP, although this is a proprietary enhancement. OSPF has direct,
standards-based support for this, but not for unequal cost routing.

Ugh, "classes" went out some time ago.

Let's work through this - I need the practice. :-)

172.92.172.20 /20 translates to: 172.92.172.20 255.255.240.0

Performing a logical "and" on the third octet of the address and the mask by
converting to binary:

172: 10101100
240:  =
=   160: 1010

We get the following network number: 172.92.160.0 for 172.92.172.20/20

If we put all "1s" in the host address, we get a broadcast address of:
172.92.175.255

So, our "supernet" range is:

172.92.160.0 to 172.92.175.255

So, using a 20 bit mask does indeed give us a supernet of 16 class "c"
address blocks, but the network number is 172.92.160.0

Hope that helps,
Irwin

May I suggest that this discussion is confusing due to classful 
terminology?  Since summarization is beyond the CCNA level, and the 
certifications beyond CCNA now assume classless addressing, it's more 
appropriate to phrase the question as:

 How many /24 prefixes will summarize into a /20?

172.x.x.x is a Class B only under classful assumptions.  Class is 
irrelevant in a classless environment.

It's also confusing to think of supernetting class C's.

He is just using poor wording.  Alot of people mix classless/classfull
which is a bad idea and bad practice.  Alot of people have it in there
head that a /24=Class C, /16=Class B and /8=Class Awhich is
definitly not the case.  I believe he was just wanting to know the number
of /24's he could bust out of the /20.

Why would you want to do such a thing??

I have my back-to-back routers in my lab connected via modem eliminators, 
but that is simply because I had the modem eliminator boxes (from Black 
Box) and I did not have any cross-over serial cables. It's a Rube Goldberg 
solution! ;-)

So I have something like this

RouterA MERouterB -ME-RouterC

With the right cables, you can simply do

RouterA RouterB RouterC

Re: unequal cost load balance using OSPF

[Dale Cantrell]

Hi all,
I was looking in Caslows book, "BRS" for some unequal load balancing in 
OSPF, and found this. Does redistrubution and administrative distance have 
something to do with this? It states, "The different values of a routing 
protocol's administrative distance can create an ideal environment for 
routing loops formation". Or am I way off again?
Thanks,

Unequal cost load-balancing is only available using IGRP and E-IGRP due to
the metric variance capability. OSPF has no means of allowing this as the
protocol is only able to support equal cost load-balancing, which goes by
the name of Equal Cost Multipath in the world of OSPF. Cisco also supports
this using RIP, although this is a proprietary enhancement. OSPF has direct,
standards-based support for this, but not for unequal cost routing.

cisco PIX firewall

[Wong, Van]

Every sample configuration on PIX I see involves NAT with public addresses
on the outside interface and private on the inside.  What if you do not want
to use NAT?  Meaning desktop PCs have global IP addresses.  So both inside,
dmz, and outside interface will have valid global ip addresses, like a class
B address subnetted.  Will PIX support that or was it designed for NAT?

I am trying to understand PIX.  I don't have access to a PIX.

Best Regards,
Van

Correct me if I'm wrong, it is a class B, subnetted into 16 class
C's. Studying for the CCNA myself, and if my understanding is wrong please

RE: unequal cost load balance using OSPF

[Kent Hundley]

OSPF does not support un-equal cost load balancing. Only IGRP and EIGRP
support this feature.

How can I configure unequal cost load balance using OSPF?
I have configured equal cost load balance and it is working fine. But,
when I try to modify the cost of any link, the load balance stop
working. What is wrong?

A customer wants us to install a new Cisco switch infrastructure. After the
install, they would like to have a documented test of the network (i.e.
under heavy load, throughput, latency, etc.). Does anyone know of a good
software package that will do this function? Thanks.

Re: Modem eliminator

Approach #1 to modem elimination with Cisco routers:

1.  Place the modem on a hard surface.
2.  Collect 2-3 strong women or men.
3.  Lift a fully loaded AGS, 7000, or higher router to a height of
 at least 3 feet.
4.  Release the router such that it falls onto the modem.
5.  If the modem is not eliminated, return to step 3.  In extreme cases,
 use a 12000 series router.

Approach #2

Virtual multipoint with STUN?

To solve this problem  it's necessary some details, but I think this
solution will work, pehaps with minor modifications.
 - Instead of assigning your private address to your client, use NAT (in
the customer side) to translate the existing customer address to your
public address or your private address. 
- Assign one IP address from network 32.82.221.32 / ...240 to your
router.
- Make the default gateway of the PC's be your router.
- In your router (in the customer side) create a static router pointing
the network address 32.82.221.32 mask 255.255.255.240 to the existing
router and a default gateway to your router.
