As OVN started implementing L3HA with the use of BFD monitoring, after
discussing with the people who is doing QA and thinking about future
troubleshooting of the feature, they proposed something the thing on
$subject.
What do you think?
For example, in this case:
[heat-admin@overcloud-novacompute-0 ~]$ sudo ovs-vsctl list Interface |
grep -E "bfd |name |bfd_status"
bfd : {}
bfd_status : {}
name : "tapc6eed125-08"
bfd : {enable="true"}
bfd_status : {diagnostic="No Diagnostic", flap_count="1",
forwarding="true", remote_diagnostic="No Diagnostic", remote_state=up,
state=up}
name : "ovn-e4dd7a-0"
bfd : {enable="true"}
bfd_status : {diagnostic="No Diagnostic", flap_count="1",
forwarding="true", remote_diagnostic="No Diagnostic", remote_state=up,
state=up}
name : "ovn-14d60a-0"
bfd : {}
bfd_status : {}
name : br-ex
bfd : {}
bfd_status : {}
name : "vlan30"
bfd : {}
bfd_status : {}
name : br-int
bfd : {}
bfd_status : {}
name : "vlan20"
bfd : {}
bfd_status : {}
name : "tapd09b3382-50"
bfd : {}
bfd_status : {}
name : "vlan50"
bfd : {}
bfd_status : {}
name : "eth0"
bfd : {enable="true"}
bfd_status : {diagnostic="No Diagnostic", flap_count="1",
forwarding="true", remote_diagnostic="No Diagnostic", remote_state=up,
state=up}
name : "ovn-c8b85a-0"
It could look like:
[heat-admin@overcloud-novacompute-0 ~]$ sudo ovs-vsctl show
