PIM Edge Mode
PIM Edge Mode is a subset of PIM that operates with the following restrictions:
•
The switch does not act as a candidate rendezvous point (CRP).
•
The switch does not act as a candidate bootstrap router (CBSR).
•
At most, two active PIM-SM interfaces are permitted. There is no restriction on the

•
Only PIM Sparse Mode (PIM-SM) is supported.
