This value indicates whether or not to monitor the route to the peers in this group so that the session can be deactivated if the route fails. Monitoring the route means DC-BGP will react to failure more quickly. For individual peers, this can be configured using bgpPeerFallover. When set to 'true', DC-BGP monitors the route to the peer and removes the session if the route fails. When set to 'false', DC-BGP does not monitor the route to the peer. When set to 'inherit', the fallover behavior for this peer is determined by the setting of the bgpRmEntFastExtFallover field. This field can be changed at any time. The change takes immediate effect.
