Advertising OVN networks over BGP

LXD
1

Hey,

I managed to succesfully advertise my OVN networks over BGP.

lxc query /internal/testing/bgp
{
        "peers": [
                {
                        "address": "192.168.3.1",
                        "asn": 65551,
                        "count": 1,
                        "holdtime": 0,
                        "password": ""
                }
        ],
        "prefixes": [
                {
                        "nexthop": "0.0.0.0",
                        "owner": "network_17",
                        "prefix": "172.25.100.0/24"
                },
                {
                        "nexthop": "0.0.0.0",
                        "owner": "network_15",
                        "prefix": "172.25.25.0/24"
                }
        ],
        "server": {
                "address": "192.168.3.197",
                "asn": 65197,
                "router_id": "192.168.3.197",
                "running": true
        }
}

The next problem I face is… traffic arrives at my LXD host (192.168.3.197) but this host doesn’t know what to do with the traffic. There’s no routes towards anything OVN related. I tried creating a route to the br-int interface but it’s down so it won’t create.

What’s the next step?

here’s some of my config:

config:
  cluster.https_address: 192.168.3.197:8443
  core.bgp_address: 192.168.3.197
  core.bgp_asn: "65197"
  core.bgp_routerid: 192.168.3.197

my uplink network:

name: guests
description: ""
type: physical
managed: true
status: Created
config:
  bgp.peers.opnsense.address: 192.168.3.1
  bgp.peers.opnsense.asn: "65551"
  ipv4.ovn.ranges: 172.25.0.0-172.25.255.255
  ipv4.routes: 172.25.0.0/16
  ovn.ingress_mode: routed

my OVN network:

name: ovn25
description: ""
type: ovn
managed: true
status: Created
config:
  bridge.mtu: "1442"
  ipv4.address: 172.25.25.1/24
  ipv6.address: none
  network: guests
