Attach Interface to Virtual Router

PUT /v2.0/routers/{router_id}/add_router_interface

Adds an internal interface to a virtual router by attaching a specified subnet or port.

• If you specify a subnet, the subnet's gateway IP is used as the interface IP by default. You may pass a custom IP within the subnet via ip_address.
• If you specify a port, the port's fixed IP is used as the interface IP.
• Only one of subnet_id or port_id must be provided.

When an IPv6 subnet is specified, it is added to an existing internal port on the same network, or a new port is created if none exists. A port can have multiple IPv6 subnets that share the same network, but only one IPv4 subnet per port is allowed.
