Figure 9: Many VLANs on One VPLS Instance

The Layer 2 PE routers are MX Series routers. Each site is connected to two P routers for
redundancy, although both links are only shown for L2-PE1 at Site 1. Site 1 is connected
to P0 and P1, Site 2 is connected to P0 and P2 (not shown), Site 3 is connected to P2
and P3, and Site 4 is connected to P1 and P3. VPLS pseudowires configured on the PE
and P routers carry traffic between the sites.
The pseudowires for the VPLS instances are shown with distinct dashed and dotted
lines. Most sites have multiple VLANs configured.
Service provider SP-1 is providing VPLS services for customer C1, services that could span
several sites. Now customer C1 can have many VLANs in the range from 1 through 1000
(for example).
