Configuring BFD Monitoring Between Active UPF and Standby UPF

Use the following configuration to configure Bidirectional Forwarding Detection (BFD) monitoring on the Active UPF and Standby UPF. Configure this command in the SRP Configuration Mode.

configure 
   context context_name 
      service-redundancy-protocol 
         [ no ] monitor bfd context context_name { ipv4_address | ipv6_address } { chassis-to-chassis | chassis-to-router } 
         end 

NOTES:

  • no : Disables BFD monitoring on the Active and Standby UPF.

  • context context_name : Specifies the context that is used. It refers to the context where the BFD peer is configured (SRP context).

    context_name must be an existing context expressed as an alphanumeric string of 1 through 79 characters.

  • ipv4 _address | ipv6_address : Defines the IP address of the BFD neighbor to be monitored, entered using IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.

    It refers to the IP address of the configured BFD (ICSR) peer.

  • chassis-to-chassis | chassis-to-router :

    chassis-to-chassis : BFD runs between primary and backup chassis on non-SRP links.

    chassis-to-router : BFD runs between chassis and router.

    Caution
    Don't use the chassis-to-router keyword for BFD monitoring on the SRP link between the Active UPF and the Standby UPF.
  • This command is disabled by default.
