Command Remarks
1. Enter system view.
system-view N/A
2. Enter PIM view.

3. Configure a filtering rule for
register messages.
register-policy acl-number
By default, no register filtering rule
exists.
4. Configure the device to
calculate the checksum based
on the entire register
message.
register-whole-checksum
By default, the device calculates
the checksum based on the header
of a register message.
Configuring switchover to SPT

failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
Both the receiver-side DR and RP can monitor the traffic rate of passing-by multicast packets and thus
trigger a switchover from RPT to SPT.
To configure the switchover to SPT:

Command Remarks

2. Enter PIM view.

3. Configure the criteria for
triggering a switchover to SPT.
spt-switch-threshold { traffic-rate |
immediacy | infinity }
[ group-policy acl-number ]
By default, the device immediately
triggers a switchover to SPT after
receiving the first multicast packet.
NOTE:
If the multicast source information is learned through MSDP, the device switches to SPT immediately after
it receives the first multicast packet, regardless of the traffic rate threshold.
Configuring PIM-SSM
PIM-SSM requires IGMPv3 support. Enable IGMPv3 on PIM routers that connect to multicast receivers.
