HP MSR2000/3000/4000 Router Series IP Multicast Command Reference

166
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# On the public network, configure a multicast data filter to accept the IPv6 multicast packets from the
IPv6 multicast source 3121::1 and discard the 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.

Predefined user roles

Parameters
traffic-rate: Specifies a traffic rate threshold for triggering a switchover to SPT, in the range of 1 to
4194304 kbps.
immediacy: Triggers a switchover to SPT immediately.
infinity: Disables switchover to SPT.
group-policy acl6-number: Specifies an IPv6 basic ACL by its number in the range of 2000 to 2999. If
an IPv6 basic ACL is specified, the configuration applies to the IPv6 multicast groups that the ACL permits.
If you do not specify an IPv6 basic ACL or the specified ACL does not exist, or if the specified ACL does
not have any valid rules, the configuration applies to all IPv6 multicast groups.
