Hi,


GRE Tunnel is successfully established between RA & SA location.

OSPF is running on Local Area Network on both location && EIGRP is running between the tunnels.

On doing show ip route at RA backbone L3-Switch we noticed tons of routes from SA and same vice-versa.

We need specific network remote network to be seen on Backbone L3-Switch. I have read route map can help in my scenario, but unfortunately it didnt work.

I would be happy to only see routes

192.168.150.0/24

192.168.100.0/24

10.255.250.0/23

saquib,


you can use prefix-list and also use distribute list to added to your EIGRP process:


ip prefix-list max24 seq 5 permit 0.0.0.0/0 ge 8 le 24

router eigrp 2

network 172.18.0.0

distribute-list prefix max24 in

Any support to get correct syntax.

Any source web link to understand different routing protocol with different filtering options with examples.
