preference on paths previously received is not changed; it is only applied to
paths received after the change. To apply the new local preference to paths
previously received, use clear ip bgp to force a soft inbound reset.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router)#bgp default local-preference 1
bgp fast-external-fallover
Use this command to configure BGP to immediately reset the adjacency with
an external peer if the routing interface to the peer goes down.
Syntax
bgp fast-external-fallover
no bgp fast-external-fallover
Default Configuration
Fast external fallover is enabled by default.
Command Mode
BGP Router Configuration mode
User Guidelines
When BGP gets a routing interface down event, BGP drops the adjacency
with all external peers whose IPv4 address is in one of the subnets on the
failed interface. This behavior can be overridden for specific interfaces using
ip bgp fast-external-fallover.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router)# bgp fast-external-fallover
