Hi all,
I'm testing the OVN BGP support in OVN IC scenario where there a few
AZs and one of them is where I have BGP support to learn external
routes and advertise overlay internal subnets.
Following is a logical router in the AZ that has the BGP support and
it is learning the IC routes from other AZs:
# ovn-nbctl lr-route-list r1
IPv4 Routes
Route Table <main>:
192.168.10.0/24 169.254.11.1 dst-ip (learned)
192.168.20.0/24 169.254.11.2 dst-ip (learned)
192.168.30.0/24 169.254.11.3 dst-ip (learned)
I can see the advertised routes to my external BGP speaker:
# ovn-sbctl list Advertised_Route
_uuid : 8f3f435d-dc3b-4926-a2d2-0acd6266f071
datapath : e632a5c1-d1ce-4f51-a2df-64d891cf43c9
external_ids : {}
ip_prefix : "192.168.10.0/24"
logical_port : b4a6588a-df77-4a3e-9de7-008028e254f1
tracked_port : []
_uuid : 21cb1532-24f8-4fa5-ad90-8f922f85a315
datapath : e632a5c1-d1ce-4f51-a2df-64d891cf43c9
external_ids : {}
ip_prefix : "192.168.20.0/24"
logical_port : b4a6588a-df77-4a3e-9de7-008028e254f1
tracked_port : []
_uuid : 70fad70a-c2f7-47d7-b3ea-def4bb521113
datapath : e632a5c1-d1ce-4f51-a2df-64d891cf43c9
external_ids : {}
ip_prefix : "192.168.30.0/24"
logical_port : b4a6588a-df77-4a3e-9de7-008028e254f1
tracked_port : []
And also the learned routes from the BGP speaker:
# ovn-sbctl list Learned_Route
_uuid : ad1a2f94-e027-4ad8-878c-839edcb12624
datapath : e632a5c1-d1ce-4f51-a2df-64d891cf43c9
external_ids : {}
ip_prefix : "10.0.0.0/24"
logical_port : b4a6588a-df77-4a3e-9de7-008028e254f1
nexthop : "169.254.1.1"
The above route is not installed into the logical router routing table:
# ovn-nbctl lr-route-list r1
IPv4 Routes
Route Table <main>:
192.168.10.0/24 169.254.11.1 dst-ip (learned)
192.168.20.0/24 169.254.11.2 dst-ip (learned)
192.168.30.0/24 169.254.11.3 dst-ip (learned)
Should the learned route be installed in the logical router routing
table? I'm trying to understand if I'm missing some step or the
current implementation can not handle it yet.
My goal is to see the external route installed in the logical router
routing table and be learned via OVN IC by the other AZs.
Regards,
Tiago Pires
