ipv6 pim rp-address IPV6-ADDRESS [GROUP-ACCESS-LIST] [override]
no ipv6 pim rp-address IPV6-ADDRESS
Parameters
IPV6-ADDRESS
GROUP-ACCESS-LIST
override
Default
No RP addresses are preconfigured.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command only affects PIM-SM operation. Use this command to statically define the RP address for
multicast groups that are to operate in sparse mode.
Users can use a single RP for more than one group. The conditions specified by the access list determine
for which groups the RP can be used. Multiple RP can be defined, each with a single access list. The
new setting overrides the old one.
All routers in a domain should have a consistent multicast group to RP mapping. The first hop router that
initiates a register message will use the mapping entries to determine the RP for sending the PIM register
message destined for a specific group. The last hop router that initiates a join message uses the mapping
entries to determine the RP for sending the join and prune message for a specific group. When a router
receives a join message, it will check the mapping entries for forwarding of the message. When a RP
receives a register message, if the router is not the right RP for the multicast group, a register-stop
message will be sent.
If the PIM domain is using embedded-RP, only the RP needs to be statically configured as the RP for the
embedded RP ranges. The other routers will discover the RP address from the IPv6 group address. If
these routers want to select a static RP instead of the embedded RP, the specific embedded RP group
range must be configured in the access list of the static RP.
Example
This example shows how to configures the RP address 3ffe:6000:3000::123 for the group access list "G1".
Switch# configure terminal
Switch(config)# ipv6 access-list G1
Switch(config-ipv6-acl)# permit any ff75::/16
Switch(config-ipv6-acl)# exit
Switch(config)# ipv6 pim rp-address 3ffe:6000:3000::123 G1
Switch(config)#
78-14 ipv6 pim spt-threshold
Specifies the IPv6 address of a router to be a PIM RP.
(Optional) Specifies the name of an access list that defines which
multicast groups the RP should be used. If no access list is configured,
the RP is used for all groups.
(Optional) Specifies that the static RP overrides dynamically learned
RP.
