Hi All,
Please advise on the below
Say I have BGP peering between A and B
R2(10.1.23.1)------(10.1.23.2)R3
Question: In seq 10 of route-map I have matched the prefix-list which matches 153.153.153.0/24 and it has to be denied. But why is it still advertised to the peer R2???
When I remove the seq 20 of the route-map, it works as intended. But shouldn't the route-map stop processing for the route 153.153.153.0/24 once it matches the seq 10?? Please advise.
