Mapping VPLS Traffic to Specific LSPs on page 75
For a VPLS routing instance, you can flood unknown unicast, broadcast, and multicast
traffic using point-to-multipoint (also called P2MP) LSPs. By default, VPLS relies upon
ingress replication to flood unknown traffic to the members of a VPLS routing instance.
This can cause replication of data at routing nodes shared by multiple VPLS members,
as shown in Figure 6 on page
provider router P1 and doubled between provider routers P1 and P2. By configuring
point-to-multipoint LSPs to handle flood traffic, the VPLS routing instance can avoid
this type of traffic replication in the network, as shown in
