Redistrubution set-up

cdad2000

Hey Everybody,

let's say we have router A,B, and C all connected thru S0/0. And we wanted to redistrubute Eigrp routes from router A to C, and vice-versa. Will the configuration have to be done on router B?

cdad2000,

If RouterA's S0/0 is connected to RouterB's S0/0, then how is RouterC's S0/0 connected to either RouterA or RouterB?

also if you do mutual resdistributionbetween AS's, try to create a route-map that "set tags" the redistributed routes and then disallow them with a route map "deny" statement from coming back from where they orginated to avoid loops. Sometimes redistributed routes can negate split-horizon rules and incorerect routes can be pushed back from where they came causing reachability issues. There are several articles on mutual redistribution with EIGRP on cisco's website.

Take a look at one of my old resitribution posts.

If you want to redestribute between multiple routing protocols then watch out for Admin, Distances and varying metrics.

This will explain why.
