Configuring Fast Refreshing of Routes with Single Next Hops

Fast refreshing routes with single next hops speeds up route convergence and reduces packet loss.

Usage Scenario

If routes have only single next hops, a link switchover takes a long time due to slow route convergence. To solve this problem, configure fast refreshing of routes with single next hops to speed up route convergence and reduce packet loss.

In VS mode, this configuration process is supported only by the admin VS.

Fast route refreshing causes a device's forwarding performance to deteriorate by about 15%. Determine whether to enable this function based on your network conditions.
