I have this config

Network 172.92.0.0 255.255.255.0

Lan 1                                  Wan  1                      Wan  2
Wan  3                        Lan 2
172.92.10.0   RouterA   72.92.20.0  RouterB  172.92.30.0  RouterC
172.92.40.0 RouterB  72.92.50.0
IGRP 80                       IGRP 20                      EIGRP 40
RIP                          IGRP 50

Problem is I can't ping from Lan 1 - Lan 2 it only goes as far as Wan 3
172.92.40.1

I know Redistribution isn't part of the CCNA curriculum but I thought I'd
give it a go.  Please forgive my ignorance, ...you can be pretty hard on
each other on this newsgroup.
