RE: Solie Enchilada Lab Redistribution Question

On a single router, routes do not seem to be fedback. This is demonstrated
by the fact that each routing protocol has to redistribute the other two
protocols into itself.

If the routes were fedback then in OSPF you would only have to redistribute
EIGRP. As EIGRP has redistributed IGRP, the IGRP originated routes should be
passed from EIGRP into OSPF. This does not happen which means you have to
explicitly redistribute IGRP into OSPF as well as EIGRP.

Hope this makes some sense?

Subject: Solie Enchilada Lab Redistribution Question

For anyone who has done the Enchilada lab, why is it
that there is absolutely no need for any route-maps on
the redistribution statements? I can understand how
the distance 150 statement for IGRP eliminates IGRP
from interfering with the OSPF routes. But what about
EIGRP and OSPF? There aren't even any passive
interface statements necessary. I'm perplexed as to
why it is so straightforward even though there is
3-way (OSPF, EIGRP and IGRP) redistribution. Perhaps
the fact that it's all happening on a single router
eliminates the need for route-maps?
