Hierarchy Level


Configure authentication key updates for the Border Gateway Protocol (BGP) and the Label Distribution Protocol (LDP) routing protocols, the Bidirectional Forwarding Detection (BFD) protocol, and the Intermediate System-to-Intermediate System (IS-IS) protocol. When the authentication-key-chains statement is configured at the [edit security] hierarchy level, and is associated with the BGP, LDP, or IS-IS protocols at the [edit protocols] hierarchy level or with the BFD protocol using the bfd-liveness-detection statement, authentication key updates can occur without interrupting routing and signaling protocols such as Open Shortest Path First (OSPF) and Resource Reservation Setup Protocol (RSVP).

The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
