Layer 3 Forwarding Cache

ip multicast route-cache readd-timeout

Command Mode

Global Configuration.

Description

This command is useful only for networks that are designed to route

 

multicast traffic. If the switch is not running IGMP-Only or a multicast

 

routing protocol on multiple IP interfaces, this command has no useful

 

effect.

 

 

Upon receiving the first frame of a new flow, the forwarding entry cache

 

software is designed to enter a cache entry in the hardware. If the

 

forwarding entry cache software continues to receive frames for the same

 

flow for a certain length of time, the software assumes that the hardware

 

was unable to install the forwarding entry when last programmed, and will

 

therefore make a new attempt.

 

The length of time for which the software waits before attempting to re-add

 

the forwarding entry is called the readd-timeout. The readd-timeout should

 

be kept small so that a missed attempt at installing a forwarding entry will

 

be recovered from quickly.

 

The default timeout is 2 seconds, and the range of adjustment is from 2 to

 

60 seconds. The no command restores the default setting.
