Adaptive filtering of bum traffic in ethernet virtual private network

An inter-connected network of Ethernet Virtual Private Networks (EVPNs), comprising:

• a plurality of Provider Edges (PEs) including a first PE and one or more second PEs, wherein the first PE is configured to:
• receive information on status of one or more nodes connected to the first PE, the one or more nodes being one of a leaf node or a root node, the status indicating whether each of the one or more nodes is one of a leaf node or a root node and whether the node is active or inactive;
• receive a respective advertisement message from the one or more second PEs;
• generate, based on the information, a route advertisement message indicative of the status of the one or more nodes connected to the first PE, wherein the route advertisement message is shared with one or more second PEs;
• and
• based on the respective advertisement message received from each of the one or more second PEs and the status of the one or more nodes connected to the first PE, dynamically adjust configurations at the first PE, to switch between ingress filtering and egress filtering of Broadcast, Unknown Unicast, and Multicast (BUM) traffic received at the first PE.

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors at a first Provider Edge (PE) of an inter-connected network of Ethernet Virtual Private Networks (EVPNs), cause the first PE to:

• receive information on status of one or more nodes connected to the first PE, the one or more nodes being one of a leaf node or a root node, the status indicating whether each of the one or more nodes is one of a leaf node or a root node and whether the node is active or inactive;
• receive a respective advertisement message from one or more second PEs of one or more second EVPNs in the inter-connected network of EVPNs;
• generate, based on the information, a route advertisement message indicative of the status of the one or more nodes connected to the first PE, wherein the route advertisement message is shared with one or more second PEs;
• and
• based on the respective advertisement message received from each of the one or more second PEs and the status of the one or more nodes connected to the first PE, dynamically adjust configurations at the first PE, to switch between ingress filtering and egress filtering of Broadcast, Unknown Unicast, and Multicast (BUM) traffic received at the first PE.
