Hi there,
I have a scenario where I want to suppress more specific route with
aggregation.
This is mostly based on the Halabi's second edition, p.351/352. Here is
a relevant config file:
router bgp 65050
no synchronization
bgp confederation identifier 3
bgp dampening route-map bgp-dampening
network 172.16.70.0 mask 255.255.255.0
network 172.16.220.0 mask 255.255.255.0
aggregate-address 172.16.0.0 255.255.0.0 suppress-map SUPPRESS
neighbor 172.16.20.1 remote-as 1
neighbor 172.16.20.1 soft-reconfiguration inbound
neighbor 172.16.70.2 remote-as 65050
neighbor 172.16.70.2 soft-reconfiguration inbound
no auto-summary
access-list 15 permit 172.16.220.0 0.0.0.255
route-map SUPPRESS permit 10
match ip address 15
I don't seem to be able to suppress this route for some reason.
Here are some outputs:
r2#sh ip bgp
BGP table version is 21, local router ID is 192.168.1.22

As you can see the route is not suppressed. What am I doing wrong here ?
Thanks.
