Description
For point-to-multipoint LSPs configured
on T Series routers, protect the Packet Forwarding Engine (PFE) from
bandwidth saturation. When a PFE does not need to replicate traffic,
the PFE’s bandwidth is less likely to become saturated. When
you include the no-mcast-replication statement, the PFE
is forced to be a leaf node in the binary tree. Leaf nodes, unlike
branch nodes, do not replicate traffic in the process of forwarding
traffic. Because leaf nodes have no children, they do not need to
replicate traffic, and thus are less likely to become saturated with
traffic.
Default
If you omit the no-mcast-replication statement, the PFE can become a branch node or a leaf node. When
the PFE becomes a branch node, the PFE must replicate traffic.
