Configuring a BFD parameter template

Ciena provides a BFD parameter template that you can use to configure BFD for each client. You can create multiple BFD parameter templates and associate a BFD parameter template with a client to configure fall-over BFD.

The following list presents some important guidelines for configuring and assigning the BFD parameter template:
  • Creating and associating the BFD parameter template is optional. If you do not specify a BFD parameter template while registering a client for BFD, the default values for minimum-tx, minimum-rx, and detect-multiplier are used. Authentication is disabled by default.
    Note: Creating and associating the BFD parameter template is mandatory for static route clients.
  • You can associate the BFD parameter template with either a source and destination address template or an interface. As the BFD template can be associated with either a source and destination address template or an interface, note the following priority levels:
    • If the BFD parameter template is associated with a source and destination address template, it has first priority.
    • If the BFD parameter template is associated with an interface, it has second priority.
    Note: Associating a BFD parameter template with an interface is supported for single-hop BFD sessions only.
  • Instead of specifying the source IP address in the BFD configuration command, you can also use the source any parameter to associate the BFD parameter template with all BFD sessions that have the specific destination. For more information, refer to BFD Commands.
  • For OSPFv3 configurations, you must specify the link local addresses for source and destination in the BFD parameter template association command instead of the interface addresses or loopback addresses. For more information, refer to an example in Configuring BFD for OSPFv3 on a physical interface by using IPv6 addressing.
  • If the parameter template is not specified, minimum-tx is taken as 300, minimum-rx is taken as 300, and the multiplier is taken as 3.
