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

Examples
# On the public network, configure an IPv6 ACL to filter IPv6 multicast data. This ACL permits the IPv6
multicast packets from the IPv6 multicast source 3121::1 and denies the IPv6 multicast packets from the
IPv6 multicast source 3121::2.

spt-switch-threshold (IPv6 PIM view)
Use spt-switch-threshold to configure the criteria for triggering a switchover to SPT.
Use undo spt-switch-threshold to restore the default.
Syntax
spt-switch-threshold { traffic-rate | immediacy | infinity } [ group-policy acl6-number ]
undo spt-switch-threshold [ traffic-rate | immediacy | infinity ] [ group-policy acl6-number ]
Default
The device immediately triggers a switchover to SPT after receiving the first IPv6 multicast packet.

Parameters
traffic-rate: Specifies a traffic rate threshold for triggering a switchover to SPT, in the range of 1 to
4194304 kbps. This argument is not supported on a switch.
immediacy: Triggers a switchover to SPT immediately.
infinity: Disables switchover to SPT.
group-policy acl6-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999. The
configuration applies to the IPv6 multicast groups that the ACL permits. The configuration applies to all
IPv6 multicast groups 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.
