REDISTRIBUTION BETWEEN RIP & EIGRP

USING REDISTRIBUTION COMMANDS

R3# config t
R3(config)#router eigrp 10
R3(config-router)#redistribute rip metric 1 subnets
R3(config)#router rip
R3(config-router)# redistribute eigrp 10 metric 1

Configuring Discontiguous networks.
A discontiguous network comprises a major net that separates another major net. In figure a subnet of network 172.20.0.0 separates network 172.16.0.0. 172.16.0.0 is a discontiguous network. RIPv1 and IGRP do not support discontiguous networks.

By using the no auto-summary command, EIGRP will advertise all the subnets between the two routers. If the networks were larger, you could then provide manual summarization on these same boundaries.
