authentication-key-chainsSyntax authentication-key-chains {key-chain key-chain-name {description text-string;key key {secret secret-data;start-time yyyy-mm-dd.hh:mm:ss;}tolerance seconds;}}Hierarchy Level [edit security]Release Information Statement introduced before Junos OS Release 10.2 for J-EX Series switches.Description Configure authentication key updates for the Border Gateway Protocol (BGP), the LabelDistribution Protocol (LDP) routing protocols, and the Bidirectional Forwarding Detection(BFD) protocol. When the authentication-key-chains statement is configured at the [editsecurity] hierarchy level, and is associated with the BGP and LDP protocols at the [editprotocols] hierarchy level or with the BFD protocol using the bfd-liveness-detectionstatement, authentication key updates can occur without interrupting routing and signalingprotocols such as Open Shortest Path First (OSPF), and Resource Reservation SetupProtocol (RSVP).Options key-chain key-chain-name—Keychain name. This name is configured at the [edit protocolsbgp] or the [edit protocols ldp] hierarchy level to associate unique authenticationkey-chain attributes with each protocol as specified using the following options:• description text-string—A text string of the authentication-key-chain. Put the text stringin quotes (“text description”).• key key—Each key within a keychain is identified by a unique integer value.Range: 0 through 63• secret secret-data—Each key must specify a secret in encrypted text or plain textformat. The secret always appears in encrypted format.• start-time yyyy–mm-dd.hh:mm:ss—Start times are specified in UTC (CoordinatedUniversal Time), and must be unique within the keychain.• tolerance seconds—Specify the clock skew tolerance, in seconds.Range: 0 through 999999999Required PrivilegeLeveladmin—To view this statement in the configuration.admin-control—To add this statement to the configuration.RelatedDocumentationConfiguring the Authentication Key Update Mechanism for BGP and LDP RoutingProtocols•1484Dell PowerConnect J-Series Ethernet Switch Complete Software Guide for Junos OS
