Configuring PIM for IPv4
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.
All routers within the same PIM-SM domain must be configured with the
◆
same RP(s). Selecting an RP through the dynamic election process is
therefore preferable for most situations. Using the dynamic RP election
process also allows a backup RP to automatically take over if the active
RP router becomes unavailable.

ARAMETERS
These parameters are displayed in the web interface:
RP Address – Static IP address of the router that will be an RP for the
◆
specified multicast group(s).
Group Address – An IP multicast group address. If a group address is
◆
not specified, the RP is used for all multicast groups.
Group Mask – Subnet mask that is used for the group address.
