Here is something I found interesting. I will ask a question and see if anyone knows the answer. This question is for CCNA'ers only. You CCNP heavy hitters don't count.
OKay say you have a router RouterA and imagine you have a diagram where there are routers to the right of RouterA off of it's serial 0/0 port and routers to the left of ROuterA off its serial 0/1 port.
And lets say that all routers off the serial 0/0 port are EIGRP routers and all routers off of serial 0/1 are IGRP routers.
Serial0/0 IP - 192.168.1.1 /24
serial 0/1 ip - 199.68.69.1 /24
YOu have issued the commands on the router:
router igrp 1
network 199.68.69.0
router eigrp 1
network 192.168.1.0
What needs to be added to make the EIGRP routers exchange routes between the left and right?
A. Nothing is needed to redestribute routes from left and right.
B Add "network 199.68.69.1" to the eigrp config
C Add network 192.168.1.0 to the igrp config
D Configure route redistribution using the "distribute" command.

There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1!

Ok, I'll seemingly take the first crack at it...I'm just now into the routing protocols...
I'd lean towards D, but I was thinking you'd have to use the "redistribute" command and not the "distribute"...unless you're distributing a filtered list...CCNA (Expired...), MCSE, CWNA, BSc Computer Science

I believe the answer is A. The router will automatically redistribute routes.

However, after looking back
, i'll go with A... CCNA (Expired...), MCSE, CWNA, BSc Computer Science

don;t worry, I thought it was D too. But it is A because EIGRP and IGRP needs no distribution or redistribution commands. As long as the AS # is the same, they will automatically redistribute the routes. I think there is one little paragraph on one page of the ICND book that states this. Very very easy to miss so thats why I thought I would paraphrase a question for yall. Was that better Mike?
