Distributed Gateway Ports

- Distributed gateway ports are logical router patch ports - that directly connect distributed logical routers to logical - switches with external connection. -

- There are two types of external connections. Firstly, connection to - physical network through a localnet port. Secondly, connection to - another OVN deployment, which will be introduced in section "OVN - Deployments Interconnection". + This section provides additional details on distributed gateway ports, + outlined earlier.
