IGRP and EIGRP will perform automatic redistribution only when they share
the same AS number. All other protocols must be manually configured to
redistribute their routes. Try your example again using IGRP 12 and EIGRP
12.

Please respond
to "Michael
Brady"
I have a question regarding redistribution. I've searched the archives,
and
I can't find
what I'm looking for. I have a simple network like the one below. We will
say that the
connections between R1, R2 & R3 are serial connections and R2 & R4 is
ethernet. The
network between R1 and R2 and a loopback on R1 is in IGRP 12, the network
between
R2 and R3 and a loopback on R3 is in EIGRP 23, and the network between R2
and R4
a loopback on each are running OSPF. On R2, I redistribute between IGRP
and
OSPF,
and between OSPF and EIGRP (not EIGRP and IGRP). My question is why don't
the
EIGRP routes show up on R1, and the IGRP routes on R3? I only see the OSPF
routes.
If I look at the OSPF database on R2, I see all of the routes. I would
think that since R2
has the routes in its OSPF database, they would be redistributed into the
other protocols.
Do I have to redistribute between EIGRP and IGRP too for this to work? Is
this supposed
to work this way, or am I missing something? Any assistance understanding
this would
be greatly appreciated.
Thanks!
Michael
