Disabling SPT switchover

If an S10500 switch acts as an RP or the receiver-side DR, it initiates an STP switchover process by default

upon receiving the first multicast packet along the RPT. You can disable the switchover from RPT to SPT.
Follow these steps to configure SPT switchover:

To do...

Use the command...

Remarks

Enter system view

system-view

Enter public network PIM view or
VPN instance PIM view

pim [ vpn-instance
vpn-instance-name ]

Disable the SPT switchover

spt-switch-threshold infinity
[ group-policy acl-number

[ order order-value] ]

Optional
By default, the device switches to the

SPT immediately after it receives the

first multicast packet.

NOTE:

For an S10500 switch, once a multicast forwarding entry is created, subsequent multicast data will not be
encapsulated in register messages before being forwarded even if a register outgoing interface is

available. To avoid forwarding failure, do not use the spt-switch-threshold infinity command on a switch

that might become an RP (namely, a static RP or a C-RP).
