Hi,
I am working on the DOIT workbook now, after doing a few Lab scenarios (The
redistribution problems of DOIT are the most complex I never have: mutual
redistribution, 3 IGP redistribution, ... etc.). I start to think that in
doing redistribtion, you have to make sure two most important things:
1. Never redistribute route originated from the routing domain back into
that routing domain: So I usually define route-map as:
route-map ospf2rip deny 10
match ip addr rip_route
route-map ospf2rip permit 20
OR
route-map ospf2eigrp deny 10
match tag <eigrp_routes>
route-map ospf2eigrp permit 20
2. Adjust AD of routes carefully at the redistribution points (the rule
is that you try to make internal routes more preference than external
routes).
I am not sure that if there are scenarios will create loops if I just
configure these two points correctly. Will post the failed scenario if I
found one.
