Redistribution Question

Redistribution Question

Redistribution Question

(OP)
=

I have a question regarding the network which is attached. I have IBGP running as my core routing protocol
and EIGRP for my remote site. I am advertising 192.168.5.0/24 via EIGRP which is redistributed into IBGP.
192.168.200.0/26 is also being redistributed into EIGRP. My problem is EIGRP is injecting 192.168.200.0/26
into IBGP again. I know i have to use filters for this subnet for it not to get injected into IBGP. But my
question is how? Meaning should i use distribute list or route map on both RTRB and RTRC to filter the
subnet? I want to filter the subnet based on how the majority of the networking industry would do it
(Real life scenarios). Im also seeing routing feedback since my EIGRP peering from RRTR to both RTRB keeps
on flapping.

Any advice on how fix these problems?


Thanks
