Bridging: Uplink protection for network isolation

With uplink protection support, you can manage network isolation by automatically shutting down Layer 2 (L2) interfaces when core isolation is detected and bringing them back up after the isolation state is cleared. This feature prevents the occurrence of traffic loops in L2 multiaccess BGP or EVPN services and improves traffic failover for multihomed customer edges during network disruptions. You can configure hold times to delay L2 interfaces' reactivation, allowing Layer 3 (L3) protocols to converge and routes to synchronize. Additionally, maintenance options enable you to bring multiple L2 interfaces up or down collectively, facilitating easier network management.
