When parsing the vnet.cfg config file we also want to get the tag
(vni or vlan). We need this so that we can lookup the vni of the passed
vnet on the status api call. We need the vni so that we can filter the
frr output.
In the future we would probably want to do this better with an enum per
vnet type and parse all possible options.

Add deserialization types for the `show bgp l2vpn evpn route vni <vni>`
command. This command shows all the L2VPN (EVPN) routes that are
distributed over BGP.

To show the routes of the Zones (L3VPN) and Vnets (L2VPN) query FRR with
different commands and parse the output. To correctly filter the Vnet
routes by Vnet we also need to read the sdn config to get the VNI. We
can use the VNI to filter the FRR output.

From: Gabriel Goller @ 2025-09-05 11:45 UTC (permalink / raw)
To: pve-devel
Add status endpoints for vnets and zones. This endpoint will return the
Layer 2 routes for zones and the Layer 3 routes for vnets.
