Create a BFD 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, and PA-5450 firewall is 50 to 10,000; range for PA-3200 Series is 100 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, and PA-5450 firewall is 50 to 10,000; range for PA-3200 Series is 100 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.
