Fast Convergence and Mass Withdrawal

When a link failure occurs between a Customer Edge (CE) device and a Provider Edge (PE) device, all remote PE devices are notified through a BGP (Border Gateway Protocol) withdrawal message of a single Ethernet Virtual Private Network (EVPN) route.

This mechanism enables the remote PE devices to reprogram the next-hop for every Media Access Control (MAC) address associated with the failed link without waiting for individual MAC withdrawal messages.
