Usage guidelines
L2VPN uses MP-BGP to exchange label blocks when creating a BGP PW.
After you execute the peer enable command, BGP can exchange label blocks with the specified peer or
peer group. To disable the capability, execute the undo peer signaling command.
Examples
# Enable BGP to exchange label block information with the peer 3.3.3.9.

Usage guidelines
In an inter-AS VPN option B network, an ASBR-PE needs to store all BGP L2VPN information (VPLS PE and
label block information discovered by BGP) and advertises the information to the remote ASBR-PE. To
meet this need, execute the undo policy vpn-target command on the ASBR-PE to accept all incoming BGP
L2VPN information.
