Mobility Optimized Networking (MON) is feature of the HCX Network Extension Service. MON enabled network extensions improve traffic flows for migrated virtual machines by enabling selective cloud routing (within the destination environment), avoiding a long round trip network path through the source gateway.

The behavior of extended networks is such that all routed traffic for migrated workloads is directed back to the source-site gateway. MON allows you to configure the optimal path for migrated workload traffic to other extended network segments, cloud-native network segments, and Internet egress.
