Description

Associate a security key with the specified BFD session using the name of the security keychain. Each key has a unique start time within the keychain. Keychain authentication allows you to change the password information periodically without bringing down peering sessions. This keychain authentication method is referred to as hitless because the keys roll over from one to the next without resetting any peering sessions or interrupting the routing protocol.

Options

key-chain-nameName of the authentication keychain. The keychain name must match one of the keychains configured with the key-chain key-chain-name statement at the [edit security authentication-key-chain] hierarchy level.
