Description
Use
peer capability-advertise orf
to enable the ORF capability for an MBGP peer or peer group.
Use
undo peer capability-advertise orf
to disable the ORF capability for the MBGP peer or peer group.
By default, the ORF capability is not enabled for an MBGP peer or peer group.

After you enable the ORF capability, the local BGP router negotiates the ORF capability with the
BGP peer through open messages. After that, the BGP router can process route-refresh messages
that carry the standard ORF information from the peer or send route-refresh messages that carry the
