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

294
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 the time-range keyword and the
fragment keyword are ignored.
You can configure multiple traffic rate thresholds by executing this command multiple times. However, if
you specify the same ACL in the commands, the most recent configuration takes effect. If the configured
traffic rate thresholds are applied to the same IPv6 multicast group, the first configuration takes effect.
Examples
# Set the traffic rate threshold for triggering a switchover to SPT to 4 kbps on the public network.
<Sysname> system-view
[Sysname] ipv6 pim
[Sysname-pim6] spt-switch-threshold 4
# Disable switchover to SPT on receiver-side DR on the public network.
<Sysname> system-view
[Sysname] ipv6 pim
[Sysname-pim6] spt-switch-threshold infinity
ssm-policy (IPv6 PIM view)
Use ssm-policy to configure the IPv6 SSM group range.
Use undo ssm-policy to restore the default.
Syntax
ssm-policy acl6-number
undo ssm-policy
Default
The IPv6 SSM group range is FF3x::/32, where x can be any valid scope.
Views
IPv6 PIM view
Predefined user roles
network-admin
Parameters
acl6-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999.
Usage guidelines
The source field in an IPv6 ACL specifies the IPv6 SSM group range. If you specify a VPN instance in the
ACL, the ACL does not take effect. The other optional parameters except the time-range keyword and the
fragment keyword are ignored.
You can use this command to define an address range of permitted or denied IPv6 multicast groups. If a
packet to an IPv6 multicast group passes the ACL, the multicast mode is IPv6 PIM-SSM. Otherwise, the
multicast mode is IPv6 PIM-SM.
Examples
# Configure the IPv6 SSM group range to be FF3E:0:8192::/96.
<Sysname> system-view
