This object indicates whether DC-RTM should use BFD to check IP reachability to the static route's next hop. DC-RTM will only attempt to use BFD if rtmEntityBfdIndex is non-zero and the static route has rtmStaticRtAction set to 'forward' and rtmStaticRtNextHop set to a non-null IP address. This object should be set as follows. - Set to 'none' if BFD is not required for this static route. - Set to 'desired' if it is not known whether the next hop router supports BFD. DC-RTM will use BFD for reachability checking if BFD is able to contact the next hop router. If the BFD session fails, the static route will be removed from the forwarding table and will not be used for redistribution. - Set to 'required' if it is known that the next hop router supports BFD. DC-RTM will use BFD to check reachability of the next hop. If BFD is unable to contact the next hop router or if the BFD session fails, the static route will be removed from the forwarding table and will not be used for redistribution. The current state of the BFD session is indicated by rtmStaticRtBfdStatus.
