1-9Configuring BGP ExtensionsIn Kompella mode, VSI uses extended BGP as the signaling protocol to distribute VC labels. Therefore,you need to configure BGP parameters on the PEs. For configuration information, refer to BGPConfiguration in the IP Routing Volume.Configuration prerequisitesBefore configuring BGP extensions, complete these tasks:z Configuring IGP on the PEs and P devices to guarantee the IP connectivity of the MPLS backbonez Configuring MPLS basic capability for the MPLS backbone on the PEs and P devicesz Configuring BGP related parameters on the PEsConfiguration procedureFollow these steps to configure BGP extensions:To do… Use the command… RemarksEnter system view system-view —Enter BGP view bgp as-number —Enter VPLS address familyview vpls-family RequiredActivate a peer peer peer-address enable RequiredNo peer is activated by default.For configurations in VPLS address family view, refer to MPLS L3VPN Configuration in the MPLSVolume.Configuring MPLS L2VPNYou must enable MPLS L2VPN before performing VPLS related configurations.
