Hello Gang,
I am trying to figure out a way to control routes
advertised by various routing protocols out particular
interfaces. For example, I have four routers: R1, R2,
R3, and R4. R1 is configured to use IGRP, OSPF, and
EIGRP. It connects to R2, R3, and R4. R1-R2 link is
running IGRP, R1-R3 link is running EIGRP, and R1-R4
link is running OSPF. I am using a class B subnet of
138.10.50.0/24 on R1-R2 link, 138.10.26.0/24 on R1-R3
link, and 138.10.36.0/24 on R1-R4 link. I only want
138.10.50.0/24 route learned by R2 via IGRP natively,
I do not want R2 to learn 138.10.36.0/24 and
138.10.26.0/24 routes as part of IGRP networks. These
two networks belong to OSPF and EIGRP respectively.
If I filter out 138.10.26.0/24 and 138.10.36.0/24, R2
will not learn them when I redistribute OSPF and EIGRP
into IGRP. I considered using route-maps,
distribute-lists, and access-lists. Passive-interface
does not apply here. I do not know what my other
options are. Any help is greatly appreciated.
Thanks,
JD
