BFD OVER VxLAN ON vPC UPLINKS

A non-transitory computer-readable medium containing instructions that, when executed by a primary vPC node, cause the primary vPC node to:

• receive a packet from a remote node;
• determine the packet includes a media access control (MAC) address corresponding to either the primary vPC or a secondary vPC node, and at least one inner packet identifier;
• identify an access control list entry from a set of access control list entries based on the at least one inner packet identifier, the access control list entry including an instruction to copy the packet;
• based on the identified ACL entry, generate a copy of the packet;
• and
• based on the determined MAC address and after generating a copy of the packet transmit the packet to the secondary vPC node.

A computing system comprising:

• a remote node;
• a dual-homed virtual tunnel endpoint (VTEP), the dual-homed VTEP including primary network switch and a secondary network switch;
• a processor;
• and
• memory containing instructions that, when executed by the processor, cause the secondary network switch to:
• receive a packet from the remote node;
• determine the packet includes a media access control (MAC) address corresponding to either the primary network switch or the secondary network switch and at least one inner packet identifier;
• identify an access control list entry from a set of access control list entries based on the at least one inner packet identifier, the access control list entry including an instruction to copy the packet;
• based on the identified ACL entry, generate a copy of the packet;
• and
• based on the determined MAC address and after generating a copy of the packet, transmit the packet to the primary network switch.
