Abstract

Techniques are described for facilitating node protection for Broadcast, unknown Unicast, and Multicast (BUM) traffic for a multi-homed node failure. For example, multi-homed provider edge (PE) devices each advertise egress node protection labels to an ingress PE device. In the event one of the multi-homed PE devices fails, the ingress PE device sends a BUM packet including the egress node protection labels for the failed node. When an egress PE device receives the BUM packet, the egress PE device determines whether the BUM packet includes the egress node protection labels and whether the egress PE device is operating as a backup designated forwarder (DF) on an Ethernet segment identifier (ESI) for which the failed node was the DF. If the BUM packet includes the egress node protection labels and the egress PE device is operating as a backup DF, the egress PE device forwards the BUM traffic to the ESI.
