proxy reroute delay

Function

The proxy reroute delay command sets a switchback delay for IGMP proxy interfaces in the IGMP view.

The undo proxy reroute delay command restores the default configuration.

By default, IGMP proxy interfaces never enter the switchback state.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this command.

Format

proxy reroute delay { delay-time | never }

undo proxy reroute delay [ delay-time | never ]

Parameters

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

Views

IGMP view of the public network instance or IGMP view of the VPN instance

Default Level

2: Configuration level

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 proxy reroute delay command to set a switchback delay for IGMP proxy interfaces in the IGMP view. The multicast routing entry update process then starts only after the specified switchback delay expires.

The proxy reroute delay command configuration applies to all IGMP proxy interfaces in the public network instance or a VPN instance. If the igmp proxy reroute delay command is also run for a specific IGMP proxy interface, the igmp proxy reroute delay command takes precedence over the proxy reroute delay command configuration.

Example

# Set the switchback delay to 100s for IGMP proxy interfaces in the public network instance.
