• Only one RP can be used for each multicast group. However, multiple
RPs can be defined for different groups or group ranges using the mask.
If a group is matched by more than one group mask, the router will use
the RP with the longer prefix length mask. If an ip pim rp-address
command specifies an IP address that was previously used for an RP,
then the older entry is replaced.
• Static definitions for RP addresses may be used together with RP
addresses dynamically learned through the bootstrap router (BSR).
• If the override parameter is used, a statistically configured RP
address will take precedence over those learned through the BSR.
Example
In the following example, the address 192.168.1.1 indicates the RP to use for all
multicast groups, and the address 10.1.1.1 indicates the RP to use for groups
224.0.0.0~224.255.255.255.
