Abstract
According to an embodiment, a network device coupled to a local base station at a cell site is configured to automatically create a more optimal route for inter-base station traffic between the local base station and a remote base station. The network device automatically discovers a remote Internet Protocol address of the remote base station used for inter-base station traffic based upon traffic transmitted by the local base station to the network device or traffic transmitted between the local and remote base stations. In response, the network device automatically installs the more optimal route entry in a routing table of the network device, which enables the network device to route inter-base station traffic originated from the local base station and destined to the remote base station using a shorter path through the backhaul network instead of routing the traffic through a mobile core network.
