R0106-HP MSR Router Series IP Multicast Command Reference(V7)

255
Parameters
ipv6-address: Specifies the IPv6 address of a C-RP.
advertisement-interval adv-interval: Specifies an interval between two C-RP-Adv messages, in the range
of 1 to 65535 seconds. The default value is 60 seconds.
group-policy acl6-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999. The C-RP
is designated only to the IPv6 multicast groups that the ACL permits. The C-RP is designated to all IPv6
multicast groups FF00::/8 when any of the following conditions exists:
• You do not specify any ACL.
• The specified ACL does not exist.
• The specified ACL does not have any valid rules.
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 for the C-RP, in the range of 1 to 65535 seconds. 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 represents a lower priority.
bidir: Specifies IPv6 BIDIR-PIM to which the C-RP is designated. If you do not specify this keyword, the
C-RP provides services for IPv6 PIM-SM.
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.
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
# On the public network, 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.
<Sysname> system-view
[Sysname] acl ipv6 number 2000
[Sysname-acl6-basic-2000] rule permit source ff0e:0:1391:: 96
[Sysname-acl6-basic-2000] quit
[Sysname] ipv6 pim
[Sysname-pim6] c-rp 2001::1 group-policy 2000 priority 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.
