Abstract
In one embodiment, a method for managing virtual link aggregation (vLAG) includes coupling a first networking switch with a second networking switch using an interswitch link (ISL), wherein the first networking switch is positioned at a boundary between Layer-2 (L2) and Layer-3 (L3), and wherein the second networking switch is positioned at the boundary between L2 and L3; creating a virtual link aggregation (vLAG) comprising connections between the first and second networking switches and an access switch in L2, wherein each networking switch comprises a virtual router redundancy protocol (VRRP) module; and interacting and modifying a VRRP state machine to perform active internet protocol (IP) forwarding when a connection between one of the networking switches and the access switch fails or one of the networking switches does not function properly.
