igmp proxy reroute delay

Function

The igmp proxy reroute delay command sets a switchback delay for an IGMP proxy interface.

The undo igmp proxy reroute delay command restores the default configuration.

By default, an IGMP proxy interface never enters the switchback state.

Format

igmp proxy reroute delay { delay-time | never }

undo igmp proxy reroute delay [ delay-time | never ]

Parameters

Parameter	Description	Value
delay-time	Sets a switchback delay for an IGMP proxy interface.	The value is an integer ranging from 10 to 86400, in seconds.
never	Indicates that an IGMP proxy interface never enters the switchback state.	-

Usage Guidelines

After a primary IGMP proxy interface recovers, multicast routing entries are updated. If the primary IGMP proxy interface fails again during an entry update, multicast traffic may be lost. To resolve such issues in primary IGMP proxy interface flapping scenarios, run the igmp proxy reroute delay command to set a switchback delay for the IGMP proxy interface. The multicast routing entry update process then starts only after the specified switchback delay expires.

Example

# Set the switchback delay to 100s for an IGMP proxy interface.
