CAUTION:
Only one candidate BSR can be configured on a Layer 3 switch. The BSR
■
configuration on another interface will replace the former configuration.
You are recommended to configure both the candidate BSR and candidate RP
■
on the Layer 3 switch in the backbone.
If the range of multicast groups that RP serves is not specified when RP is
■
configured, the RP serves all multicast groups. Otherwise, the RP serves the
multicast groups within the specified range.
You can configure basic ACLs to filter related multicast IP addresses and control
■
the range of multicast groups that RP serves.
If you use static RPs, all routers in the PIM domain must adopt the same
■
configuration.
If the configured static RP address is the address of an UP interface on the local
■
switch, the switch will serve as RP.
