Disabling The Switchover To Spt; Configuring Ipv6 Pim-Ssm - HP 6125G Configuration Manual

Configure a filtering rule for register messages on all C-RP routers, and configure them to calculate the
checksum based on the entire register messages. Configure the register suppression time and the register
probe time on all routers that might become IPv6 source-side DRs.
To configure register-related parameters:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure a filtering rule for
register messages.
4. Configure the device to
calculate the checksum based
on the entire register
messages.
5. Configure the register
suppression time.
6. Configure the register probe
time.

Disabling the switchover to SPT

CAUTION:
If the switch is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
If an HP 6125 Blade switch acts as an RP or the receiver-side DR, it initiates the switchover to SPT by
default upon receiving the first IPv6 multicast packet along the RPT. You can disable the switchover from
RPT to SPT.
To configure the switchover to SPT:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Disable the switchover to
SPT.

Configuring IPv6 PIM-SSM

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