Abstract
Presented herein are systems and methods that provide traffic recover when virtual router redundancy protocol (VRRP) virtual media access control (VMAC) failures occur in a link aggregation group fabric environment. In one or more embodiments, automatic traffic recovery may be accomplished using internode link control messages to synchronize a VRRP VMAC failure that has been encountered by one LAG node with a LAG peer node. If a database associated with the failed LAG node comprises no entry that indicates that the failure scenario has previously occurred in the LAG peer node, a forwarding path entry rule may be generated to route traffic via the internode link, thereby, reducing data loss through routing failures and the like.
