LDP signaling—VPLS with LDP signaling, which is referred to as LDP-based VPLS, uses
LDP as the protocol that signals reachability for the VPLS domain in which the VPLS
instance participates. You must configure LDP on each PE router in your topology to
provide signaling for each VPLS domain.
Figure 128 on page 574 illustrates an example of a simple VPLS topology. The basic
topology of a VPLS network is the same regardless of whether BGP signaling or LDP
signaling is used.
