isis wait-timer
Sets the period of time in which the Avici router collects adjacency information about all other routers on the LAN.
Syntax: isis wait-timer seconds
no isis wait-timer
seconds
The number of seconds to wait before exiting to the waiting state. The number of seconds should be in the range of 0 to 65535.
Description: The wait timer defines the period of time in which the Avici router collects adjacency information about all the other routers on the LAN. This information is used to select the designated router for the LAN when the wait timer expires. This command is for broadcast networks only.
The wait timer determines how long a router waits before coming out of the wait state. If you extend the number of seconds that the router remains in the wait state, you increase the amount of time a router takes to reach convergence. However, you also increase the probability that other routers that will contend for designated router also have a chance to come up before convergence.
Use the isis wait-timer seconds command to configure the number of seconds the router will wait for adjacency information.
WARNING The wait timer must be the same for all routers attached to a network.
Use the no isis wait-timer to configure the number of seconds the router will wait for adjacency information to the default value of 20 seconds.
Factory Default: 20 seconds (2 times the hello timer)
Command Mode: Interface configuration.
Example: In the following example:
- The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration.
- The net command configures a NET for the routing process.
- The interface pos n/n/n identifies a specific POS interface and changes the command mode to Interface configuration.
- The ip router isis command enables the IS-IS process specified by the global router isis command on the interface.
- The isis wait-timer seconds command sets the number of seconds the router will wait for adjacency information to 30 seconds.
- The show running-config interface command displays the setting:
router(config)#router isis 0
router(config-router)#net 49.0001.0000.0000.1111.00
router(config-router)#interface pos 1/5/1
router(config-if)#ip router isis 0
router(config-if)#isis wait-timer 30
router(config-if)#end
router#show run int
