Configuring graceful shutdown for a specific BGP4 neighbor

Configuring graceful shutdown for a specific BGP4 neighbor minimizes traffic loss during a planned shutdown of a single neighbor by rerouting traffic to an alternate path before the shutdown.

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

   device# configure terminal

2. Enable BGP routing.
   

   device(config)# 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

5. Configure graceful shutdown of the neighbor.
   

   device(config-bgp-router)# neighbor 10.11.22.13 graceful-shutdown 600 community 30

   This example configures graceful shutdown of the neighbor (10.11.22.13) after 600 seconds and sets the community attribute to 30.
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
     neighbor 10.11.12.13 remote-as 2
     neighbor 10.11.12.13 graceful-shutdown 600 community 30

Example

The following example shows how to configure graceful shutdown of a specific BGP4 neighbor (10.11.22.13) after 600 seconds. The community attribute is also set to 30.

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)# neighbor 10.11.22.13 graceful-shutdown 600 commuity 30
