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

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

    Caution
    Do not 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.
