peer bfd
Use peer bfd to enable BFD for a BGP peer.
Use undo peer bfd to disable BFD for a BGP peer.
Syntax
peer ip-address bfd
undo peer ip-address bfd
Default
BFD is disabled.
Views
BGP view, BGP-VPN instance view
Default command level
2: System level
Parameters
ip-address: IP address of a peer.
Usage guidelines
After the link to the BGP peer fails, BFD may detect the failure before the system performs GR, causing GR
to fail. If GR capability is enabled for BGP, use BFD with caution. If GR and BFD are both enabled, do
not disable BFD during a GR process; otherwise, GR may fail.
