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, four active PIM-SM interfaces are permitted. There is no restriction on the number of passive interfaces (within the limit of the maximum IP interfaces).
Only PIM Sparse Mode (PIM-SM) is supported.

Note

This feature is supported at and above the license level listed for this feature in the license tables in the Switch Engine v33.1.1 Licensing Guide document.

Active PIM interfaces can have other PIM enabled routers on them. Passive interfaces should only have hosts sourcing or receiving multicast traffic. If another PIM router is connected to a multi-access VLAN, then passive mode should not be enabled for that respective VLAN. OSPF passive mode should not be enabled for a VLAN when a PIM neighbor is present.
