Step Command Remarks
6. Configure the register probe
time.
probe-interval interval
Optional.
5 seconds by default.
Configuring SPT switchover
Both the receiver-side DR and the RP can periodically check the traffic rate of passing-by IPv6 multicast
packets (this function is not available with switches) and thus trigger RPT-to-SPT switchover.
Perform the following configuration on routers that might become receiver-side DRs and on C-RP routers.
To configure SPT switchover:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure the SPT switchover.
spt-switch-threshold infinity
[ group-policy acl6-number [ order
order-value ] ]
Optional.
By default, the device switches to
the SPT immediately after it
receives the first IPv6 multicast
packet from the RPT.
Configuring IPv6 PIM-SSM
NOTE:
The IPv6 PIM-SSM model needs the support of MLDv2. Be sure to enable MLDv2 on IPv6 PIM routers with
receivers attached to them.
IPv6 PIM-SSM configuration task list
Task Remarks
Enabling IPv6 PIM-SM Required
Configuring the IPv6 SSM group range Optional
Configuring IPv6 PIM common features Optional
Configuration prerequisites
Before you configure IPv6 PIM-SSM, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer
• Determine the IPv6 SSM group range
