HAVE 2 CISCO ROUTER 2501.
I NEED TO CONFIG IGRP AND I HAVE PROBLEM

ROUTER A:
E0 IP 192.168.2.8 -> FOR NETWORK 192.168.2.0
S0 IP 192.168.10.2
ROUTER IGRP 1
NETWORK 192.168.4.0
NETWORK 192.168.10.0

ROUTER B:
E0 IP 192.168.4.1
S0 IP 192.168.10.1
ROUTER IGRP 1
NETWORK 192.168.2.0
NETWORK 192.168.10.0


NOW WHEN I SHOW IP ROUTE
IN ROUTER B I SEE IGRP WORKING FOLLOWING,
I 192.168.2.0/24 ROUTING VIA 192.168.10.2 SERIAL 0

LATER
I SEE
I 192.168.2.0/24 IS POSSIBLE DOWN, ROUTING VIA 192.168.10.2, SERIAL 0

AND
ROUTER A I DO NOT SEE IGRP WORKING AT ALL


CAN ANYONE HELP ME WHAT DID I DO WRONG.

THANKS A LOT
TOM

your LAN network are reversed. your current config does not allow the LAN
segments to participate in your routing protocol

ROUTER A
ROUTER IGRP 1
NETWORK 192.168.2.0
NETWORK 192.168.10.0

ROUTER B:
ROUTER IGRP 1
NETWORK 192.168.4.0
NETWORK 192.168.10.0

Thanks for advise.
I think I did try this LAN network reverse. It does not learn the network
next door.
I have 2 router 2501 with dce serial cable connect to dte serial cable to
router B.
but I will you advise again.
thanks
