I'm practicing some routing techniques related to the Implementing Cisco IP Routing class and exam. I'm trying to manufacture a routing loop in order to correct it with route maps and prefix lists, etc. I can't seem to get the routing loop to appear the way I thought it would, and I would like a hand.
Please consider the following topology (linked from Photobucket):
The lab is intended to feature mutual redistribution at two points, creating a routing loop. When I redistribute EIGRP into OSPF at R1, for example, R2 gets the routes expected in it's routing table. R2's next hop is R1 to reach the 192.168.253/254.0 networks (this is expected for now). When I try to redistribute EIGRP into OSPF at R2 there seems to be no effect. R1 maintains its routing table - it's as if the redistribution commands at R2 never happened. If I redistribute in the opposite order (R2 before R1) I have the opposite scenario.
Can someone please tell me what I'm doing wrong? I have the lab sitting in front of me, so I'll be happy to provide any other details required.
Thanks for your time.
