C HAPTER 21 | Multicast Routing
Configuring PIMv6 for IPv6
– 860 –
◆ 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 PIM6-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.
PARAMETERS
These parameters are displayed:
◆ 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 Prefix Length – An IPv6 network prefix length for a multicast
group. (Range: 8-128)
WEB INTERFACE
To configure a static rendezvous point:
1. Click Routing Protocol, PIM6, PIM6-SM.
2. Select RP Address from the Step list.
3. Specify the static RP to use for a multicast group, or a range of groups
by using a subnet mask.
4. Click Apply.
