Examples of Viewing VRRP Sessions
To view the established sessions, use the show bfd neighbors command.
The bold line shows that VRRP BFD sessions are enabled.
To view session state information, use the show vrrp command.
The bold line shows the VRRP BFD session.
Changing VRRP Session Parameters
BFD sessions are congured with default intervals and a default role.
The parameters that you can congure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. You can
change parameters for all VRRP sessions or for a particular neighbor.
To change parameters for all VRRP sessions or for a particular VRRP session, use the following commands.
• Change parameters for all VRRP sessions.
INTERFACE mode
vrrp bfd all-neighbors interval milliseconds min_rx milliseconds multiplier value role [active
| passive]
• Change parameters for a particular VRRP session.
INTERFACE mode
vrrp bfd neighbor ip-address interval milliseconds min_rx milliseconds multiplier value role
[active | passive]
To view session parameters, use the show bfd neighbors detail command.
Disabling BFD for VRRP
If you disable any or all VRRP sessions, the sessions are torn down.
A nal Admin Down control packet is sent to all neighbors and sessions on the remote system change to the Down state.
To disable all VRRP sessions on an interface, sessions for a particular VRRP group, or for a particular VRRP session on an interface, use the
following commands.
• Disable all VRRP sessions on an interface.
INTERFACE mode
no vrrp bfd all-neighbors
• Disable all VRRP sessions in a VRRP group.
VRRP mode
bfd disable
• Disable a particular VRRP session on an interface.
INTERFACE mode
no vrrp bfd neighbor ip-address
