Vxlan static routing for virtual network feature

[Shurik12]

1. Now in OpenSDN we can add static route to port: create interface route table with some static routes and attach to port (any virtual machine interface)
2. But if we create route table with any static routes and attach it to virtual network then this bundle will not work by vxlan protocol (for mpls it works good)
3. I suggest to implement this functionality as follows:
4. 1. When we attach rt to vn, we search appropriate vmi by next-ho ip
      3.2. Call attach this route table to appropriate vmi method

Could you please also explain how do you create static routes for a virtual network?

[Shurik12]

Yes, sure:

1. ifmap abstraction layer: added connections between virtual network and route table (virtual-network-route-table), virtual machine interface and route table (virtual-machine-interface-route-table, the same as for interface route table connection)
2. agent abstraction layer: in BuildData method for vn we check node on cfg_route_table typethen -> p. 3
3. graph traversal and search cfg_vm_interface_table and check on equivalence (instance-ip and next-hop), also check address pair ip
4. If we found, I create connection request for current route-table node object and founded virtual machine interface node object.

Thanks, still I do not understand in which scenario interface route tables (IRT) do not work with VxLAN. We checked it and it worked (at least a couple of years ago). Or do you want to use another tool such as network route tables, which I haven't used earlier?

Yes, here we talking about "Network Route Table" to provision static route inside virtual network in format:

prefix 10.10.10.0/24 next-hop-type ip-address next-hop 10.10.20.10

We want to see EVPN TYPE 5 route inside internal virtual network route table for this static route

There are two things that confuse me.

1. Whereas you mentioned "Network Route Table", a pointer to an object of class InterfaceRouteTable is used, is it what was expected?
2. The proposed changes pertain to VxLAN CP, however I don't see that VxlanRoutingManager class is involved.

Maybe there are more questions from my colleagues.
