A single VPLS routing instance can encompass one set of PE routers that use BGP for
signaling and another set of PE routers that use LDP for signaling. Within each set, all of
the PE routers are fully meshed in both the control and data planes and have a
bidirectional pseudowire to each of the other routers in the set. However, the BGP-signaled
routers cannot be directly connected to the LDP-signaled routers. To be able to manage
the two separate sets of PE routers in a single VPLS routing instance, a border PE router
must be configured to interconnect the two sets of routers.
The VPLS RFCs and Internet drafts require that all of the PE routers participating in a
single VPLS routing instance must be fully meshed in the data plane. In the control plane,
each fully meshed set of PE routers in a VPLS routing instance is called a PE router mesh
group. The border PE router must be reachable by and have bidirectional pseudowires
to all of the PE routers that are a part of the VPLS routing instance, both the LDP-signaled
and BGP-signaled routers.
NOTE: In the VPLS documentation, the word router in terms such as PE router
is used to refer to any device that provides routing functions.
For LDP BGP interworking to function, LDP-signaled routers can be configured with
forwarding equivalence class (FEC) 128 or FEC 129.
