Figure 64: 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 64 on page 1280, 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
