Hi guys,
I have an issue with a remote site. it routes traffic to my primary site via a backup tunnel rather than the neighbor MPLS site. I cant see why this is happening.
Please see the below config snipt and see what I'm doing wrong. My knowledge of BGP is limited and i'm coming into this problem after it was configured so i'm having trouble see whats wrong. I did notice however the the ACL 20 referenced in the route map below is not in the ACL list. If i'm using 172.16.128.0 and 172.16.129.0 what should my mask be 0.0.127.255???
