BGP Signaling for VPLS
BGP multiprotocol extensions (MP-BGP) enable BGP to support IPv4 services such as
BGP/MPLS VPNs, which are sometimes known as RFC 2547bis VPNs. VPLS with BGP
signaling is actually a BGP-MPLS application that has much in common with BGP/MPLS
VPNs.
The procedures for configuring BGP signaling for BGP/MPLS VPNs and for VPLS are
similar except, for VPLS, you must configure both of the following BGP address
families:
BGP can exchange information in a VPLS topology within these address families.
Specifically, BGP builds a full mesh of label-switched paths (LSPs) among all of the
VPLS instances on each of the PE routers participating in a particular VPLS domain.

LDP Signaling for VPLS
When you configure VPLS with LDP signaling, LDP supports a full mesh of
pseudowires among the participating PE routers. This is analogous to BGP signaling,
in which BGP builds a full mesh of label-switched paths (LSPs) among all of the VPLS
instances on each of the PE routers participating in a particular VPLS domain.
Targeted Sessions
LDP establishes targeted sessions to the remote PEs configured at the edge of the
service provider's MPLS core network. The number of targeted sessions supported

L2VPN The L2VPN address family enables you to configure the PE router for
VPLS (or VPWS) L2VPNs to exchange layer 2 network layer reachability
information (NLRI) for all VPLS (or VPWS) instances. Optionally, you can use the
signaling keyword with the address-family command for the L2VPN address
family to specify BGP signaling of VPLS reachability information. Currently, you
can omit the signaling keyword with no adverse effects.
VPLS The VPLS address family enables you to configure the PE router to
exchange layer 2 NLRI for a specified VPLS instance.
