HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

342
After you execute the peer advertise-community command, routing updates advertised to the peer carry
the
COMMUNITY attribute.
After you execute the undo peer advertise-community command, BGP, upon receiving a route with the
COMMUNITY attribute, removes the COMMUNITY attribute before sending the route to the peer or peer
group.

# In BGP IPv4 unicast address family view, advertise the COMMUNITY attribute to peer group test.

[Sysname] bgp 100
