R3303-HP HSR6800 Routers IP Multicast Command Reference

374
Default
The device switches to the SPT immediately after it receives the first IPv6 multicast packet.
Views
IPv6 PIM view
Default command level
2: System level
Parameters
infinity: Disables switchover to SPT.
group-policy acl6-number: Specifies a basic IPv6 ACL number in the range of 2000 to 2999. If you do
not include this option in your command, the configuration applies to all IPv6 multicast groups.
order order-value: Specifies the order of the IPv6 ACL in the group-policy list. The value range for the
order-value argument is from 1 to the largest order value in the existing group-policy list plus 1, but the
value range should not include the original order value of the IPv6 ACL in the group-policy list. If you
have assigned an order-value to a certain IPv6 ACL, do not specify the same order-value for another IPv6
ACL. Otherwise the system will give error information. If you do not specify an order-value, the order
value of the IPv6 ACL will remain the same in the group-policy list.
Usage guidelines
To adjust the order of an IPv6 ACL that already exists in the group-policy list, you can use the acl6-number
argument to specify this IPv6 ACL and set its order-value. This inserts the IPv6 ACL to the position of
order-value in the group-policy list. The order of the other existing IPv6 ACLs in the group-policy list
remains unchanged.
To use an IPv6 ACL that does not exist in the group-policy list, you can use the acl6-number argument to
specify an IPv6 ACL and set its order-value. This inserts the IPv6 ACL to the position of order-value in the
group-policy list. If you do not include the order order-value option in your command, the ACL is
appended to the end of the group-policy list.
If you use this command multiple times on the same IPv6 multicast group, the first traffic rate configuration
matched in sequence takes effect.
If the router is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
Examples
# Create a group-policy with the basic IPv6 ACL number of 2010, disable the switchover to SPT, and
insert the IPv6 ACL to the first position.
