Depends what you want to do. Juniper supports static BFD, or BFD for OSPF & ISIS ... even PIM
BFD is compatible with Cisco, just watch the version number, Juniper supports v0 and v1, not sure Cisco does v1 (didn't the last time I looked) static : (looks a bit strange due to next hop and neighbor being the same as the route ... the 1.1.1.2 is adjacent to your interface) routing-options { static { route 1.1.1.2/32 { next-hop 1.1.1.2; bfd-liveness-detection { neighbor 1.1.1.2; minimum-interval 100; <-- milliseconds multiplier 3; } } } } ISIS protocols { isis { interface ge-0/0/0.0 { bfd-liveness-detection { version automatic; minimum-interval 100; multiplier 3; } } } } OSPF protocols { ospf { area 0.0.0.0 { interface ge-0/0/0.0 { bfd-liveness-detection { version automatic; minimum-interval 100; multiplier 3; } } } } } By default this runs on the RE .. so can be limited if you have many sessions. However turning on this knob .... # show routing-options ppm { delegate-processing; } ...will enable it on the PFE .. hence will scale much better. This only works on the later Juniper models though. cheers Sean Bit Gossip wrote: > I read in a Juniper preso, that BFD can work at layer 2 on a ethernet > link, but I can not find any reference in the Junos doc.
