Figure 2: BGP and LDP Signaling for a VPLS Routing Instance

Two-way pseudowires are established between the PE routers in each mesh group and
between each PE router in the VPLS routing instance and the border router. In
Figure 2 on page 13, two-way pseudowires are established between routers PE1 and PE2
in mesh group LDP-1, routers PE3, PE4, and PE5 in mesh group LDP-2, and routers PE6,
PE7, and PE8 in the BGP mesh group. Routers PE1 through PE8 also all have two-way
pseudowires to the Border router. Based on this topology, the LDP-signaled routers are
able to interoperate with the BGP-signaled routers. Both the LDP-signaled and
BGP-signaled PE routers can logically function within a single VPLS routing instance.
NOTE: The following features are not supported for VPLS routing instances
configured with both BGP and LDP signaling:
Point-to-multipoint LSPs
Integrated routing and bridging
IGMP snooping
