Abstract
A method and system for steering bidirectional network traffic to a same service device. Specifically, the disclosed method and system entail the maintaining and synchronization of link aggregation group (LAG) tables tied to a pair of LAG ports instantiated on a network element directly connected to a pair of peer linking service devices. Network traffic (i.e., MAC frames) arriving at the network element, from a first host and intended for a second host (e.g., indicative of a first direction of the network traffic), may be steered towards one of the pair of service devices based on hashing of information included in a received MAC frame in conjunction with the LAG table tied to the LAG port (of the pair of LAG ports) that which received the MAC frame.
