Description Tim Rozet 2021-01-21 21:09:41 UTC 
Description of problem:
Currently with the BFD implementation in OVN the way to configure it on a route is like this:

1. uuid=$(ovn-nbctl create bfd logical_port=rp-public dst_ip=172.16.1.50 min_tx=250 min_rx=250 detect_mult=10)
2. ovn-nbctl lr-route-add R1 100.0.0.0/8 172.16.1.50
3. route_uuid=$(fetch_column nb:logical_router_static_route _uuid ip_prefix="100.0.0.0/8")
4. ovn-nbctl set logical_router_static_route $route_uuid bfd=$uuid

The association between the route and the bfd entry has to be manually done as an extra step. The request here is that we consolidate that into the lr-route-add command. Therefore we would do:
1. uuid=$(ovn-nbctl create bfd logical_port=rp-public dst_ip=172.16.1.50 min_tx=250 min_rx=250 detect_mult=10)
2. ovn-nbctl lr-route-add R1 100.0.0.0/8 172.16.1.50 bfd $uuid

This should also work for using the bfd name.
