EoGRE Layer 2 Tunnel

This example configures a Ethernet-over-GRE layer 2 tunnel and a bridge:

  • create a bridge interface br0
  • create a EoGRE tunnel eogre to 192.0.2.2 using VNI 42
  • add eogre and the interface eth0 to the bridge br0
  • disable STP on the bridge br0
  • set all interface link states to up
interfaces:
  br0:
    link:
      kind: bridge
      br_stp_state: 0
      state: up
  eth0:
    link:
      kind: physical
      master: br0
      state: up
  eogre:
    link:
      kind: gretap
      gre_local: 192.0.2.1
      gre_remote: 192.0.2.2
      master: br0
      state: up

{
  networking.ifstate = {
    enable = true;
    settings = {
      interfaces = {
        br0 = {
          link = {
            kind = "bridge";
            br_stp_state = 0;
            state = "up";
          };
        };
        eth0 = {
          link = {
            kind = "physical";
            master = "br0";
            state = "up";
          };
        };
        eogre = {
          link = {
            kind = "gretap";
            gre_local = "192.0.2.1";
            gre_remote = "192.0.2.2";
            master = "br0";
            state = "up";
          };
        };
      };
