Establishing a BFD Session

Procedure

1. Run system-view

   The system view is displayed.

2. According to whether BFD detects an IPv4 or IPv6 link, perform either of the following operations:

   • Run the bfd session-name bind peer-ip peer-ip [ vpn-instance vpn-name ] [ interface { interface-name | interface-type interface-number } ] source-ip source-ip auto command to set up a static BFD session for IPv4 with automatically negotiated discriminators.

     

     • A source address must be configured.
     • The IP address must be an explicit IPv4 address but not a multicast one.

   • Run the bfd session-name bind peer-ipv6 peer-ipv6 [ vpn-instance vpn-name ] [ interface interface-type interface-number ] source-ipv6 ipv6-address auto command to set up a static BFD session for IPv6 with automatically negotiated discriminators.

     

     • A source address must be configured.
     • The IP address must be an explicit IPv6 address but not a multicast one.

3. Run commit

   The configuration is committed.
