Very Computer

We're having a (new) routing problem. This probably never worked
to begin with since it's never been used this way...

I think the problem is at RtrB - IGRP & EIGRP wierdness and
distribution.

Problem is remote office (& RouterA) can't ping Host198 below.
The route to 198.203.172.0 network isn't getting propagated
to RtrA.

remote office--RtrA(7000)_TR1/1--TR0_RtrB(4000)_E0--Host198

RtrA is 10.3(10)
RtrB is 10.3(10)

TR1/1 is  205.130.32.230
TR0 is 205.130.32.231
Host198 is 198.203.172.2

RtrA conf:
router eigrp 100

TokenRing1/1
BUT THIS WASN'T THERE UNTIL I ADDED A STATIC THEN REMOVED IT.
THE DYNAMIC STAYED THERE EVEN THOUGH IT SHOULD BE THERE I THINK.

RtrB conf:

 redistribute igrp 1
 network 146.138.0.0
 network 198.203.172.0
 network 205.130.32.0

access-list 1 permit 205.254.135.0
access-list 1 permit 146.138.244.0

and this in in RtrB's ip route cache:
C    198.203.172.0 is directly connected, Ethernet0

Michael,

I drew a mud-map of your network and as I understand it your problem is
on Router A, not router B.

I am assuming that your remote office Lan on router A is network
205.130.37.0 which is being advertised using IGRP 1.  Network
205.130.37.0 is not being re-distributed to EIGRP on Router A, so
although router A knows about Network (Host198) 198.203.172.2, Router B
does not know about network 205.130.37.0.

This could easily be confirmed by a "show ip routes" on Router B.  So
your pings to Host198 would know how to get to the destination network
BUT your Router B would not know how to get back to your remote network.

This problem could be resolved by either:
1.  Redistributing EIGRP 100 into IGRP 1 on Router A
2.  Redistributing IGRP 1 into EIGRP 100 on Router A
3.  Adding Network 205.130.37.0 to IGRP 1 on Router A
4.  Adding Network 205.130.37.0 to EIGRP 100 on Router A

The reason points 3 and 4 work is because it appears as though for this
section of your network you have almost created complete overlapping
routing domains for all of the networks connected to Router A and B that
you showed in your diagram.  Is that what you intended?

I hope this helps.
