You are right that "debug ip bgp" and its variants do not seem to
include community information in its output.
For troubleshooting, check the following:
1. Don't forget to use "send community" in your config.
2. On the receiving end of the community string, "show ip bgp <nlri>".
You should see the community at the bottom of the output.
See below for an example:
SENDING SIDE:
router bgp 1
neighbor 10.1.1.2 remote-as 2
neighbor 10.1.1.2 send-community
neighbor 10.1.1.2 route-map send-it out
!
route-map send-it permit 10
set community 6
RECEIVING SIDE:
r2501b#sh ip bgp 172.16.1.0/24
BGP routing table entry for 172.16.1.0/24, version 9
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Not advertised to any peer
1 65530
10.1.1.1 from 10.1.1.1 (172.17.1.1)
Origin IGP, localpref 100, valid, external, best
Community: 6
r2501b#
Hope that helps.
