With respect to the previous implementation, OVN is now tracking and
flushing ECMP next-hop ct entries with the next-hop mac address instead
of using an identification number committed by ovn-northd since the previous
approach had some limitations when the traffic is initialized from outside
the ovn cluster. This series is introducing a way to periodically resolve L2
address of the configured next-hops.
Please note IPv6 is not currently supported and it will be added before posting
a formal series. The goal of this series is just to collect feedbacks about the
proposed approach.
Changes in RFC v3:
- move ecmp-next-hop-monitor code in controller/ecmp-next-hop-monitor.{c,h}
- use a hamp for send_arp_nd_data since the same nexthop can be used by
multiple ports/routes
- add new system-ovn test to check when a given next-hop is used by multiple
ovn-routers/ecmp routes
- use a Port_Binding reference in ECMP_Nexthop
- use nexthop and port as ECMP_Nexthop table index
- move ECMP_Nexthop mac binding update in mac_binding_add_to_sb()
- cosmetics
Changes in RFC v2:
- add IPv6 support
Lorenzo Bianconi (4):
northd: Introduce ECMP_Nexthop table in SB db.
pinctrl: Send periodic arp/nd to ecmp next-hops.
pinctrl: Update ecmp-nexthop mac resolving L2 address.
ofctrl: Introduce ecmp_nexthop_monitor.
