Syntax: [no] neighbor ip-addr shutdown [ generate-rib-out ]
The ip-addr parameter specifies the IP address of the neighbor.
Optional BGP4 configuration tasks
The following sections describe how to perform optional BGP4 configuration tasks.
Changing the Keep Alive Time and Hold Time
The Keep Alive Time specifies how frequently the device will send KEEPALIVE messages to its BGP4 neighbors. The Hold Time
specifies how long the device will wait for a KEEPALIVE or UPDATE message from a neighbor before concluding that the neighbor is
dead. When the device concludes that a BGP4 neighbor is dead, the device ends the BGP4 session and closes the TCP connection to
the neighbor.
The default Keep Alive time is 60 seconds. The default Hold Time is 180 seconds.
NOTE
Generally, you should set the Hold Time to three times the value of the Keep Alive Time.
NOTE
You can override the global Keep Alive Time and Hold Time on individual neighbors.
To change the Keep Alive Time to 30 and Hold Time to 90, enter the following command.
device(config-bgp-router)# timers keep-alive 30 hold-time 90
Syntax: [no] timers keep-alive num hold-time num
For each keyword, num indicates the number of seconds. The Keep Alive Time can be 0 - 65535. The Hold Time can be 0 or 3 -
65535 (1 and 2 are not allowed). If you set the Hold Time to 0, the device waits indefinitely for messages from a neighbor without
concluding that the neighbor is dead.
Changing the BGP4 next-hop update timer
By default, the device updates the BGP4 next-hop tables and affected BGP4 routes five seconds after IGP route changes. You can
change the update timer to a value from 1 through 30 seconds.
To change the BGP4 update timer value to 15 seconds, for example, enter the update-time command at the BGP configuration level of
the CLI.
device(config-bgp-router)# update-time 15
Syntax: [no] update-time secs
The secs parameter specifies the number of seconds and can be from 0 through 30. The default is 5. The value of 0 permits fast BGP4
convergence for situations such as link-failure or IGP route changes. Setting the value to 0 starts the BGP4 route calculation in sub-
second time. All other values from 1 through 30 are still calculated in seconds.
