Claim:
1. A method in a first cell site router that is communicatively coupled to first radio base station (RBS) of a Radio Access Network (RAN) for automatically establishing a short network route to a second RBS that is communicatively coupled to a second cell site router, the method comprising: receiving, at the first cell site router, a packet originated by the second RBS that is destined to the first RBS via an X2-C interface, wherein the packet comprises a Stream Control Transmission Protocol Initialization Acknowledgement (SCTP INIT ACK) message acknowledging an initiation of a SCTP association between the first RBS and the second RBS, wherein the packet travelled on a long network route; responsive to a determination that the received packet comprises the SCTP INIT ACK message, discovering, by the first cell site router, a remote network address of the second RBS from within the packet; and creating the short network route between the first RBS and the second RBS based upon the discovered remote network address of the second RBS.
