An engineer configures a route map on R1 to tag routes learned from a customer eBGP peer with community 65000:100 so an upstream provider can filter them. After applying the policy, the neighbor R2 (the upstream) reports that none of the received prefixes carry the community. The relevant configuration on R1 is: route-map SET-COMM permit 10 match ip address prefix-list CUST-NETS set community 65000:100 ! router bgp 65000 neighbor 10.1.1.2 remote-as 65001 neighbor 10.1.1.2 route-map SET-COMM out The prefixes are being advertised to R2 correctly, but without the community value. What is the most likely cause?
