Egress node protection for broadcast, unknown unicast, or multicast traffic in EVPN topologies

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a first device, cause the one or more processors to:
• establish a peering session with a second device;
• receive network traffic including a first label,
• the first label being a multicast label associated with the second device,
• the second device being a designated forwarder for an Ethernet segment;
• determine a second label based on receiving the network traffic including the first label,
• the second label being used to route the network traffic to a customer edge device, via a third device, rather than the second device,
• the third device being a non-designated forwarder for the Ethernet segment;
• store information that identifies the first label and an operation associated with the first label,
• the operation being associated with removing the first label from the network traffic and including the second label with the network traffic;
• and
• provide the network traffic, including the second label, to the third device to permit the third device to provide, via the Ethernet segment, the network traffic to the customer edge device based on the information that identifies the first label and the operation associated with the first label.

A method, comprising:

• establishing, between a first device and a second device, a peering session;
• determining, by the first device, a failure associated with the second device,
• the second device being a designated forwarder for an Ethernet segment associated with an Ethernet virtual private network instance;
• receiving, by the first device, network traffic including a first label,
• the first label being a multicast label associated with the second device;
• determining, by the first device, a second label based on receiving the network traffic including the first label and based on determining the failure associated with the second device,
• where determining the second label comprises:
• determining the second label based on a third label associated with the network traffic;
• determining, by the first device, the third label associated with the network traffic,
• the third label indicating that the network traffic is to be forwarded to the second device;
• and
• providing, by the first device, to a third device, and without providing to the second device, the network traffic including the second label to permit the third device to provide, via the Ethernet segment, the network traffic to a customer edge device based on the second label,
• the customer edge device being associated with the Ethernet virtual private network instance.
