PIM Multicast Routing
– 1590 –
ipv6 pim rp-address This command sets a static address for the Rendezvous Point (RP) for a
particular multicast group. Use the no form to remove an RP address or an
RP address for a specific group.
S YNTAX
[no] ipv6 pim rp-address rp-address [group-prefix group-prefix]
rp-address - Static IPv6 address of the router that will be an RP for
the specified multicast group(s).
group-prefix - An IPv6 network prefix for a multicast group. If a
group prefix is not specified, the RP is used for all multicast groups.

◆ The router specified by this command 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 specific group ranges.
◆ Using this command to configure multiple static RPs with the same RP
address is not allowed. 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 with
this command.
◆ 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.
◆ If the no form of this command is used without specifying a multicast
group, all multicast groups are removed.
