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... 

Use the command...

Disable 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.  

 

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). 

 

 

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.
