ip multicast graceful-restart

Use the command to specify the maximum time to wait for Multicast protocol

convergence.

ip multicast graceful-restart {convergence-time TIME | leak interval INTERVAL}

Default convergence-time TIME-60 seconds.

leak interval INTERVAL-200 seconds.

Command Mode Global Configuration.

Usage Guideline When a router in a multicast process (such as PIM-SM, DVMRP, PIM-DM) has

NSF enabled, the router is said to be NSF-capable and will operate in graceful

restart mode-the RP router process performs nonstop forwarding recovery due to

a Route Processor (RP) switchover. When the local multicast process is

performing graceful restart/gracefully restart, the local forwarding database will

remain as unchanged until restart-time expires and the local system will be aged

out/refresh the obsolete forwarding information data. The feature assists in the

nonstop forwarding recovery process.

As local multicast process restart over, there is a time interval which is used for

packet-leak control. In the period of the interval, multicast packets are leaked to

local CPU interface.

Examples This example shows how to set the maximum time to wait for protocol

convergence to 300 seconds.

Syntax Description

convergence-time

TIME

(Optional) Specifies the maximum time to wait for protocol convergence; valid

values are from 60 to 3600 seconds.

leak interval

INTERVAL

(Optional) Specifies the packet-leak interval; valid values are from 20 to 3600

seconds.
