Building Blocks of a BFD Profile
- Network > Network Profiles > BFD Profile
You can enable BFD for a static route or dynamic routing protocol
by applying the default BFD profile or a BFD profile that you create.
The default profile uses the default BFD settings and cannot be
changed. You can
Add
a new BFD profile and
specify the following information.BFD Profile Settings | Description |
---|---|
Name | Name of the BFD profile (up to 31 characters).
The name is case-sensitive and must be unique on the firewall. Use
only letters, numbers, spaces, hyphens, and underscores. |
Mode | Mode in which BFD operates:
|
Desired Minimum Tx Interval (ms) | Minimum interval (in milliseconds) at which
you want the BFD protocol to send BFD control packets. Minimum value
on PA-7000/PA-5000 Series is 50; minimum on PA‑3200 Series is 100;
minimum on VM-Series is 200 (maximum value is 2000; default is 1000). If you have multiple protocols that use
different BFD profiles on the same interface, configure the BFD
profiles with the same Desired Minimum Tx Interval . |
Required Minimum Rx Interval (ms) | Minimum interval (in milliseconds) at which
BFD can receive BFD control packets. Minimum value on PA-7000/PA-5000
Series is 50; minimum on PA-3200 Series is 100; minimum on VM-Series
is 200 (maximum value is 2000; default is 1000). |
Detection Time Multiplier | 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 (range is 2-50; default is 3). |
Hold Time (ms) | Delay (in milliseconds) after a link comes
up before the firewall transmits BFD control packets. Hold
Time applies to BFD Active mode only. If the firewall
receives BFD control packets during the Hold Time ,
it ignores them (range is 0-120000; default is 0). The default setting
of 0 means no transmit Hold Time is used;
the firewall sends and receives BFD control packets immediately
after the link is established. |
Enable Multihop | Enables BFD over multiple hops. Applies
to BGP implementation only. |
Minimum Rx TTL | Minimum Time-to-Live value (number of hops)
BFD will accept (receive) when it supports multihop BFD. Applies
to BGP implementation only (range is 1-254; there is no default). |
