Quidway S7700 Smart Routing Switch
Configuration Guide - Multicast
As shown in
with the PIM GR function forwards multicast data to the receiver, the master MPU backs up the
PIM routes and Join/Prune messages to be sent to the upstream device to the slave MPU. When
the active/standby switchover occurs on SwitchC, the LPUs maintain the existing forwarding
entries to ensure uninterrupted forwarding of multicast data. The receiver can always receive
multicast data from the source during the active/standby switchover.

Configure the IP addresses and unicast routing protocols on the physical interfaces of the
switch matching the VLANIF interfaces.
Enable the unicast GR function on each switch and set the GR period.
Enable the multicast function, enable PIM-SM on the interface of the switch, and enable
IGMP on the interface connecting switch to the host.
Configure an RP. Configure same static RPs on the switches.
Enable the PIM GR function on SwitchC and set the GR period.
