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 { immediacy | infinity } [ group-policy acl6-number ]
undo spt-switch-threshold [ immediacy | infinity ] [ group-policy acl6-number ]
Default
The device immediately triggers a switchover to SPT after receiving the first IPv6 multicast packet.
Views

Parameters
immediacy: Triggers a switchover to SPT immediately.
infinity: Disables switchover to SPT.
group-policy acl6-number: Specifies an IPv6 basic ACL, 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 no IPv6
basic ACL is specified, the configuration applies to all IPv6 multicast groups.

source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
The source field in an ACL specifies the IPv6 multicast group range. If you specify a VPN instance in the
ACL, the ACL does not take effect. The other optional parameters except time-range are ignored.
