Abstract
A wireless telemetry process (WTP) may obtain telemetry data which includes signal strength information associated with a plurality of fabric wireless access points (APs) of a network fabric. The WTP may identify that a signal strength between a current AP and a wireless endpoint is below a threshold. In response, the WTP may select addresses of a set of handoff candidate APs for the wireless endpoint based on the signal strength information. The WTP may communicate, to a map server, a message to register, as entries in a replication list, a plurality of routing locators associated with the addresses of the set of handoff candidate APs for association with an address of the wireless endpoint. The map server may notify a router of the replication list, for replicating packets intended for the wireless endpoint to a plurality of routers that are connected to the set of handoff candidate APs.
