The overload protection enable command enables overload protection in the global routing policy or multi-ISP policy-based route.
The undo overload protection enable command disables overload protection.
By default, overload protection is enabled for intelligent uplink selection.
When the bandwidth usage and overload protection threshold are specified on an intelligent uplink selection member interface, if the bandwidth usage of a link reaches the overload protection threshold, the FW excludes the overloaded link and selects routes from unoverloaded links. When a link is overloaded, new sessions need to be switched to another link, affecting service experience.
The FW supports the use of the undo overload protection enable command to disable the link overload protection function for a global routing policy or a specified multi-ISP policy-based route. In this case, the link is not switched even if it is overloaded.
