Where does raven0 link gets its parentIndex? #138
Comments
Also seems when there isn't such an error ("error get vxlan parent"...), seems the code path is not triggered and ParentIndex is 0 as well. |
Why your default route is point to a vxlan interface?usually it will point to |
ah... I think it's due to our customization, on our edge side, nodes can't talk to each other with their private ip directly; we have to rely on vxlan; that should be why I think I should just customize it further and do not check parent index of the vxlan? seems it's just never set. Not sure if doing this for raven also makes sense through; the other approach is to set parent index during vxlan creation |
@suyuee I'm not sure if vxlan(
can you open a pr to fix it ? |
Thanks for the insights, will open a pr for it. (kinda busy recently, but will do once I get a chance) Btw, we don't use vxlan over vxlan, but just using raven vxlan fwiw |
I noticed in our setup the wireguard fails to set up properly sometimes. due to
So the problems is the parent index is 0;
code pointer:
raven/pkg/networkengine/routedriver/vxlan/utils.go
Lines 261 to 266 in 3197c5d
But it seems when creating the vxlan link, the code doesn't actually specify a parentIndex here:
raven/pkg/networkengine/routedriver/vxlan/vxlan.go
Lines 264 to 274 in 3197c5d
When searching the netlink repo, I don't see the parentIndex field set for vxlan links (not sure if it's https://github.com/vishvananda/netlink/blob/77df5d35f725f10c8ca5f5552c95782fd639b46c/link_linux.go#L2098)
Any thoughts? Thanks in advance
