A mechanism for initiating route optimization in an administrative domain. The mechanism is actualized when traffic is exchanged between at least a first mobile node and a second mobile node, said traffic taking place over at least one Local Mobility Anchor (LMA) within said administrative domain. The traffic exchange between said first and second mobile nodes within the administrative domain is detected followed by a decision to initiate route optimisation for the traffic. Thereafter an optimized route for the traffic, in which the traffic is routed directly between a first and a second mobile access gateway (MAG) serving the first and the second mobile nodes, respectively, is created. A route optimisation update is then sent directly or indirectly, to any uninformed mobile access gateway (MAG), after which the traffic is routed directly between the first and the second MAG. This method for route optimization may be applied in a Proxy Mobile IP (PMIP) context.
