R21xx-HP FlexFabric 11900 IP Multicast Command Reference

146
the ACL. If the group-policy acl-number option is not specified, if the specified ACL does not exist, or if
the specified ACL does not have any valid permit statement, the C-RP is designated to all IPv6 multicast
groups FF00::/8.
scope scope-id: Specifies the ID of an IPv6 admin-scoped zone, in the range of 3 to 15.
holdtime hold-time: Specifies a lifetime (in seconds) for the C-RP, in the range of 1 to 65535. The default
value is 150 seconds.
priority priority: Specifies a priority for the C-RP, in the range of 0 to 255. The default setting is 192. A
larger value indicates a lower priority.
Usage guidelines
The IPv6 address of a C-RP must be the IPv6 address of a local IPv6 PIM enabled interface on the C-RP.
Otherwise, the configuration does not take effect.
In an ACL, the source field specifies the IPv6 multicast group range to which the C-RP is designated, and
the other fields are ignored. If the specified IPv6 addresses are not IPv6 multicast addresses, the ACL is
not valid. Only groups that match a permit statement in the ACL are advertised.
If you do not specify an IPv6 multicast group range or an IPv6 admin-scoped zone to which the C-RP is
designated, the C-RP provides services for the IPv6 multicast groups in the range of FF00::/8.
To use a C-RP for multiple IPv6 multicast group ranges, specify them by multiple permit statements in an
ACL and reference the ACL in the group-policy keyword.
If you execute this command using the same IPv6 address of a C-RP multiple times, the most recent
configuration takes effect.
Examples
# Configure the interface with the IPv6 address of 2001::1 as the C-RP for IPv6 multicast group range
FF0E:0:1391::/96, and set its priority to 10.

crp-policy (IPv6 PIM view)
Use crp-policy to configure the legal C-RP address range and the IPv6 multicast group range to which the
C-RP is designated.
Use undo crp-policy to remove the configuration.
Syntax
crp-policy acl6-number
undo crp-policy
Default
No restrictions are defined for the legal C-RP address range and the IPv6 multicast group range to which
the C-RP is designated. All received C-RP messages are regarded legal.
