Enabling Igmp Nsr - HP FlexNetwork 7500 Series Configuration Manual

Enabling IGMP NSR

This feature enables the switch to back up information about IGMP interfaces and IGMP forwarding
entries to the standby process. After an active/standby switchover, the switch can recover the
information without cooperation of other devices. This prevents the active/standby switchover from
affecting the multicast service.
To enable IGMP NSR:
Step
Enter system view.
1.
Enable IGMP NSR.
2.
Configuring IGMP SSM mappings
This feature enables the switch to provide SSM services for IGMPv1 or IGMPv2 hosts.
This feature does not process IGMPv3 messages. As a best practice, enable IGMPv3 on the
receiver-side interface to ensure that IGMPv3 reports can be processed.
Configuration prerequisites
Before you configure IGMP SSM mappings, complete the following tasks:
•
Configure any unicast routing protocol so that all devices in the domain can interoperate at the
network layer.
•
Configure basic IGMP features.
