  • Support for single-hop BFD echo-lite sessions in distributed and inline mode (MX204, MX240, MX301, MX304, MX480, MX960, MX2008, MX2010, MX2020, MX10003, MX10004, MX10008, and MX10016)—You can configure single-hop BFD echo-lite sessions in inline and distributed modes to monitor forwarding path availability for directly connected next hops. Unlike regular echo sessions, echo-lite sessions work even if the next-hop device is not configured for BFD. Use the following configuration command to configure BFD echo-lite sessions:

    set routing-options static route address bfd-liveness-detection echo-lite minimum-interval interval
