NOTE
If destination port 3784 is used by the multi-hop BFD control packets on a router, the router can successfully
negotiate with the router on which destination port 4784 is used by the multi-hop BFD control packets. At
the same time, on the router that is configured with destination port 3784, destination port 3784 is
automatically updated to destination port 4784. To change the destination port number, run the
shutdown command to terminate the BFD session on destination port, then, run the multi-hop destination-
port command on destination ports 4784 and 3784, and finally run the undo shutdown command to restore
the BFD session.
NOTE
You can view information about the BFD session and its statistics only after BFD session parameters are
configured and the BFD session is set up successfully.
Run the display bfd session { all | discriminator discr-value | dynamic | peer-ip peer-
ip [ vpn-instance vpn-instance-name ] | static } [ verbose ] [ slot slot-id ] command to
view information about the BFD session.
Run the display bfd statistics [ slot slot-id ] command to view information about statistics
of global BFD.
