I don't seen any network been advertize from AS 300. How is this summarization suppose to work if there are no networks in the 132.x.0.0 being advertised?
Just wan to know if I'm missing something.
Agreed. I simply temporarily added Vlan 5 as a network statement to make the aggregate appear and to make sure I knew what I was advertising to R3 and BB2. Once I was done testing, I removed the network statement.
As for how we're supposed to know if we've missed some other way we should have had a route out of 132.x.0.0, there's nothing in the tasks, so I assume we're all set.
On another note, the SG shows the following configuration for peers 126.96.36.199 and 188.8.131.52:
neighbor <address> route-map DENY_AGGREGATE out
ip prefix-list DENY_AGGREGATE seq 5 permit 184.108.40.206/16
route-map DENY_AGGREGATE deny 10
match ip address prefix-list DENY_AGGREGATE
route-map DENY_AGGREGATE permit 20
and in the explanation below, it indicates at the very end that "...Finally, and unsuppress-map is applied to the other BGP neighbors."
But that's not an unsuppress-map...
