Route-Map (BGP)

[ksarin123_2]

Hello folks -

I am using a route-map in BGP to filter some routes from an eBGP neighbor. However, the filtering is not working as expected.

Not sure where am I going wrong. Below is the config.

ip prefix-list deny_rsa seq 5 permit 10.20.30.0/24
ip prefix-list deny_rsa seq 10 permit 10.20.40.0/24

route-map test deny 10
match ip address deny_rsa

route-map test permit 20

router bgp 11
no synchronization
bgp log-neighbor-changes
network 10.10.12.0 mask 255.255.255.0
neighbor 10.10.12.1 remote-as 11

neighbor 10.10.12.1 route-map test in
no auto-summary

Essentially, I am trying to filter 10.20.30.0/24 & 10.20.40.0/24 but somehow this config is not working as expected.

Can any one tell where is my logic wrong?

Thanks for your help.

Hello,

You have a small error in your route-map - your route-map refers to an ACL deny_rsa which does not exist, instead of referring to a prefix-list. Correctly, your route-map should be:

route-map test deny 10

match ip address prefix deny_rsa

!

route-map test permit 20

Don't forget to perform the clear ip bgp * in command after you modify or apply the route-map.

Best regards,

Peter
