These encapsulation modes do not offer the tunnel end-points the required semantics to expose a service identifier that can be used to identify traffic for a certain classification, such as for supporting mobile nodes that are using overlapping private IPv4 addressing. The extension defined in this document allow the mobile access gateway and the local mobility anchor to negotiate GRE encapsulation mode and exchange the GRE keys for marking the flows, so that differential processing can be applied by the tunnel peers over those flows.}, }
