[pve-devel] [PATCH pve-network v4 8/9] api: nodes: zones: add ip vrf endpoint for evpn zones

[Stefan Hanreich <s.hanreich@proxmox.com>]

This endpoint returns the state of the routing table on a node for a
given EVPN zone. This is used by the SDN browser panel to display
status information in the UI.
