Abstract
Methods and apparatus for operating a virtual node in a LAG that includes a first virtual node and a second virtual node are disclosed. The first virtual node includes at least a first fellow node and a second fellow node. In one exemplary method, the first fellow node receives, from the second virtual node, first control information comprising a system ID and first configuration information associated with the LAG. The first control information is compared with reference configuration information representing previously established expected configuration information associated with the LAG. Based on that comparison, and at least one additional criterion, a split brain condition may be determined to exist in the LAG. In a complementary fashion, a fellow node of the second virtual node may be configured to alter its transmitted configuration information depending on whether it is able to communicate with its fellow node in the second virtual node.
