neighbor fall-over
Syntax
neighbor {<IP-ADDR>|<PEER-GROUP-NAME>} fall-over
no neighbor {<IP-ADDR>|<PEER-GROUP-NAME>} fall-overDescription
Enables BGP fast peering session deactivation. When neighbor fall-over is configured, the BGP process monitors the RIB and if the route to peer is not present in the routing table, it immediately deactivates the peer session without waiting for the hold down timer. It is disabled by default.
The
no form of this command disables this feature.
Command context
config-bgp
Parameters
<IP-ADDR>Specifies an IP address.
<PEER-GROUP-NAME>Specifies a peer group.
Authority
Administrators or local user group members with execution rights for this command.
Usage
Neighbor fall-over does not track connected or static routes to peers. However, this is not an issue when IBGP peering is using a loopback interface. To force a fall-over for connected and static routes, use the command
neighbor fall-over bfd.
Examples
switch(config-bgp)# neighbor 1.1.1.1 fall-over switch(config-bgp)# no neighbor 1.1.1.1 fall-over
switch(config-bgp)# neighbor PG fall-over switch(config-bgp)# no neighbor PG fall-over
