Abstract
Techniques for optimizing traffic flows via MAC synchronization when server virtualization is used with dynamic routing are provided. In one embodiment, a first network device can store an interface MAC address of a second network device in an L2 forwarding table, where the first network device and the second network device are peer nodes in an MC-LAG cluster. Further, the first network device can enable a flag for the interface MAC address in the L2 forwarding table. When the first network device receives a data packet that includes the interface MAC address of the second network device as a destination MAC address, the first network device can determine that the interface MAC address is included in the L2 forwarding table with the flag enabled. The first network device can then perform a lookup into its L3 routing table, identify a next hop destination for the data packet, and route the packet to the destination.
