At this point we have OSPF running in the core, and
MPLS running as well on the LSR routers. From this point on we'll focus on the
LERs that actually connect to the customers. We'll add an additional bridge for
VPLS traffic, configure OSPF and MPLS with LDP on each of the LERs, then we'll
move on to building the VPLS tunnels.

This is MPLS
at work, associating routes with labels for quick lookup, which is what gives
MPLS its trademark performance boost over regular end-to-end IP routing. We're
ready now to add the VPLS tunnels and start moving some traffic transparently
between sites. The extra bridge interfaces that we added on the two LERs will
be used to bridge the VPLS virtual interfaces with physical Ethernet interfaces
that we hand off to the customer.
