To enable Bidirectional Forwarding Detection
(BFD) for BGP globally for the virtual router on a PA-3000 Series, PA-5000
Series, PA-5200 Series, PA-7000 Series, or VM-Series firewall, select
one of the following:
an existing BFD profile on the firewall
New BFD Profile
to disable BFD for all BGP interfaces
on the virtual router; you cannot enable BFD for a single BGP interface.
If you enable or disable BFD globally, all
interfaces running BGP are taken down and brought back up with the BFD
function, which can disrupt BGP traffic. Therefore, enable BFD on
BGP interfaces during an off-peak time when reconvergence does not
impact production traffic.
