Configuring graceful shutdown for all BGP4 neighbors

Configuring graceful shutdown for all BPG4 neighbors minimizes traffic loss during a planned shutdown of all neighbors by rerouting traffic to alternate paths before the shutdown.

1. From privileged EXEC mode, enter global configuration mode.
   

   device# configure terminal

2. Enable BGP routing.
   

   device(config-rbridge-id-122)# router bgp

3. Configure the autonomous system number (ASN) in which your device resides.
   

   device(config-bgp-router)# local-as 1000

4. Add a neighbor.
   

   device(config-bgp-router)# neighbor 10.11.12.13 remote-as 2

   Repeat this step for all neighbors on the device.
5. Configure graceful shutdown for all neighbors.
   

   device(config-bgp-router)# graceful-shutdown 600 community 10 

   This example configures graceful shutdown for all neighbors after 600 seconds and sets the community attribute to 10. The graceful-shutdown command gracefully shuts down all neighbors on the node. When a route map is not specified, default graceful shutdown parameters are applied. When a route map is specified, only route-map parameters are applied.
6. Return to privileged EXEC mode.
   

   device(config-bgp-router)# end

7. Verify the configuration.
   

   device# show running-configuration router bgp
   
    router bgp
     local-as 1000
     graceful-shutdown 600 community 10

Example

The following example shows how to configure graceful shutdown of all BGP4 neighbors after 600 seconds. The community attribute is also set to 10.

device# configure terminal	
device(config)# router bgp
device(config-bgp-router)# local-as 1000
device(config-bgp-router)# neighbor 10.11.12.13 remote-as 2
!
!
device(config-bgp-router)# graceful-shutdown 600 community 10
