The mpp-active-reselection enable command enables active MPP reselection.
The undo mpp-active-reselection command disables active MPP reselection.
By default, active MPP reselection is disabled.
Usage Scenario
After active MPP reselection is enabled on an MP, the MP evaluates MPPs of the same Mesh ID and on the same channel based on the signal strength of Mesh links, and the numbers of link hops and Mesh links. If a more preferable MPP is available, the MP selects the MPP as its Mesh gateway.
By default, active MPP reselection is disabled, and an MP can only passively reselect MPPs. Only when the minimum RSSI of all Mesh links on the optimal route to the current MPP is lower than the RSSI threshold of a Mesh link, the MP triggers the MPP reselection process.
Precautions
The configuration does not take effect on MPPs or vehicle-mounted APs in train-ground communication scenarios because the vehicle-mounted APs select MPPs based on the fast link handover algorithm.
Active MPP reselection will cause service loss. Configure the function according to actual needs.
