High Availability

  • Support for inline BFD (QFX5220)—Starting in Junos OS Evolved Release 23.2R1, QFX5220 devices support centralized and inline BFD.

  • MPLS fast reroute for SR tunnels using S-BFD (PTX10008, PTX10016)—Starting in Junos OS Evolved Release 23.2R1, we support MPLS fast reroute for segment routing (SR) tunnels configured with Seamless BFD (S-BFD). When S-BFD detects a path failure for an SR tunnel, the MPLS FRR feature provides fast traffic recovery. Use the sbfd-frr configuration statement at the [edit protocols source-packet-routing] hierarchy level to enable S-BFD FRR support.
