  • 1.  Question on L2Circuit BFD

     
    Posted 10-01-2022 06:05

    Hi.

     

    On a vMX I have configured BFD under my L2circuit and have 2 questions:

    1: Why is my BFD session down?

    2: Why is my L2circuit session still up? Shouldn't the failed BFD have brought down the L2circuit session?

     

    set protocols l2circuit neighbor 2.2.2.2 interface ge-0/0/0.512 virtual-circuit-id 1

    set protocols l2circuit neighbor 2.2.2.2 interface ge-0/0/0.512 pseudowire-status-tlv

    set protocols l2circuit neighbor 2.2.2.2 interface ge-0/0/0.512 oam bfd-liveness-detection minimum-interval 1000

    set protocols l2circuit neighbor 2.2.2.2 interface ge-0/0/0.512 oam bfd-liveness-detection multiplier 5

    jcluser@PE1# run show bfd session
