COMMAND USAGE
◆ The router will act as an RP for all multicast groups in the local PIM-SM
domain if no groups are specified. A static RP can either be configured
for the whole multicast group range 224/4, or for specific group ranges.
◆ If an IP address is specified that was previously used for an RP, then
the older entry is replaced.
◆ Multiple RPs can be defined for different groups or group ranges. If a
group is matched by more than one entry, the router will use the RP
associated with the longer group prefix length. If the prefix lengths are
the same, then the static RP with the highest IP address is chosen.
◆ Static definitions for RP addresses may be used together with RP
addresses dynamically learned through the bootstrap router (BSR). If
an RP address learned by the BSR and one statically configured using
this command are both available for a group range, the RP address
learned by the BSR is chosen over the one statically configured.
