Layer 3 Routing Commands 1267
bgp fast-internal-fallover
Use the bgp fast-internal-fallover command to configure BGP to
immediately reset the adjacency with an internal peer when there is a loss of
reachability to an internal peer.
Syntax
bgp fast-internal-fallover
no bgp fast-internal-fallover
Default Configuration
By default, fast internal fallover is enabled.
Command Mode
BGP Router Configuration mode
User Guidelines
BGP tracks the reachability of each internal peer’s IP address. If a peer
becomes unreachable (that is, the RIB no longer has a non-default route to
the peer’s IP address), BGP drops the adjacency.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router)# bgp fast-internal-fallover
bgp listen
Use the bgp listen command to create an IPv4 listen range and associates it
with the specified peer template. The bgp listen command also activates the
IPv4 or IPv6 BGP dynamic neighbors feature. Use the no form of the
command to remove an IPv4 or IPv6 listen range.
