Create a Bidirectional Forwarding Detection profile.

BFD Routing Profiles	Description
Name	Enter a name for the BFD profile (maximum of 63 characters). The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore (_) or hyphen(-). No dot (.) or space is allowed.
Mode	Select mode: • Active—(default) BFD initiates sending control packets to peer. At least one of the BFD peers must be Active; both can be Active. • Passive—BFD waits for peer to send control packets and responds as required.
Desired Minimum Tx Interval (ms)	Minimum interval, in milliseconds, at which you want the BFD protocol to send BFD control packets; you are thus negotiating the transmit interval with the peer. Range for PA-7000 Series, PA-5200 Series, PA-5400 Series, and PA-3400 Series is 50 to 10,000; range for PA-3200 Series is 100 to 10,000; range for PA-400 Series is 150 to 10,000; range for VM-Series is 200 to 10,000; default is 1,000.
Desired Minimum Rx Interval (ms)	Minimum interval, in milliseconds, at which BFD can receive BFD control packets. Range for PA-7000 Series, PA-5200 Series, PA-5400 Series, and PA-3400 Series is 50 to 10,000; range for PA-3200 Series is 100 to 10,000; range for PA-400 Series is 150 to 10,000; range for VM-Series is 200 to 10,000; default is 1,000.
Detection Time Multiplier	Range is 2 to 255; default is 3. The local system calculates the detection time as the Detection Time Multiplier received from the remote system multiplied by the agreed transmit interval of the remote system (the greater of the Required Minimum Rx Interval and the last received Desired Minimum Tx Interval). If BFD does not receive a BFD control packet from its peer before the detection time expires, a failure has occurred.
Hold Time (ms)	Delay, in milliseconds, after a link comes up before BFD transmits BFD control packets. Hold Time applies to BFD Active mode only. If BFD receives BFD control packets during the Hold Time, it ignores them. Range is 0 to 120,000; default is 0, which means no transmit Hold Time is used; BFD sends and receives BFD control packets immediately after the link is established.
Enable Multihop	Enable BFD over BGP multihop.
Minimum Rx TTL	Enter the minimum Time-to-Live (number of hops) BFD will accept (receive) in a BFD control packet when BGP supports multihop BFD. Range is 1 to 254; there is no default.
