Configuring SPT Switchover

If an S7900E series routing switch acts as an RP or the receiver-side DR, it initiates an STP switchover
process (by default) upon receiving the first IPv6 multicast packet along the RPT. You can disable the
switchover from RPT to SPT.
Follow these steps to disable SPT switchover:
To do...
Enter system view
Enter IPv6 PIM view
Disable the SPT switchover
For an S7900E series Ethernet switch, once an IPv6 multicast forwarding entry is created, subsequent
IPv6 multicast data will not be encapsulated in register messages before being forwarded even if a
register outgoing interface is available. Therefore, to avoid forwarding failure, do not use
spt-switch-threshold infinity command on a switch that may become an RP (namely, a static RP or a
C-RP).

Configuring IPv6 PIM-SSM

The IPv6 PIM-SSM model needs the support of MLDv2. Therefore, be sure to enable MLDv2 on IPv6
PIM routers with receivers attached to them.

packet from the RPT.
