Disable the SPT switchover

For a 3Com Switch 4800G, 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.

Complete these tasks to configure IPv6 PIM-SSM:

Enabling IPv6 PIM-SM

Configuring the IPv6 SSM Group Range

Configuring IPv6 PIM Common Features

Before configuring IPv6 PIM-SSM, complete the following task:

Configure any IPv6 unicast routing protocol so that all devices in the domain are interoperable at

the network layer.

Before configuring IPv6 PIM-SSM, prepare the following data:

The IPv6 SSM group range

Use the command...

spt-switch-threshold infinity

[ group-policy acl6-number

[ order order-value ] ]

By default, the device switches

to the SPT immediately after it

receives the first IPv6 multicast

packet from the RPT.
