    Hierarchy Level

    [edit interfaces aex aggregated-ether-options bfd-liveness-detection]

    Release Information

    Statement introduced in Junos OS Release 13.3.


    Configure the authentication criteria of the BFD session for aggregated Ethernet interfaces.


    algorithm algorithm-name

    Specify the algorithm to be used to authenticate the BFD session. You can use one of the following algorithms for authentication:

    • keyed-md5
    • keyed-sha-1
    • meticulous-keyed-md5
    • meticulous-keyed-sha-1
    • simple-password
    key-chain key-chain-name

    Specify the name that is associated with the security key for the BFD session. The name you specify must match one of the keychains configured in the authentication-key-chains key-chain statement at the [edit security] hierarchy level.


    (Optional) Configure loose authentication checking on the BFD session. Use only for transitional periods when authentication might not be configured at both ends of the BFD session.
