Hello,
This is my topology:
r1s0--r2s0
r2s1--r3s0
r2e0--r4e0
r1 and r2 are running IGRP and r2, r3 and r4 are running OSPF. r2 is doing
mutual redistribution which works fine EXCEPT for the serial link between r2
and r3. If I add the 'summary-address 10.1.23.0 255.255.255.0' to the ospf
process on r2, the network shows up on r1. I then save all configs, reload
the routers and the 10.1.23.0 network will not summarize and get
redistributed. I have included the configs and route tables for r1 and r2
both before and after reload. If anyone can shed some light on this, it
would be greatly appreciated.
Thank you.
Peter
