Displaying the multicast NSR status
Syntax: ip multicast-nonstop-routing
During a hitless upgrade and switchover, this syslog message is generated on the CLI. The message displayed depends on which version of PIM is configured.
PIM v4 is configured
MCASTv4 protocol receives switchover event
Mcastv4 protocol switchover done
PIM v6 is configured
MCASTv6 protocol receives switchover event
Mcastv6 protocol switchover done
The syslog message shows the state transition of multicast NSR as the standby module takes over as the active module. The multicast data traffic will continue to flow during state transition.
