Abstract:
Methods, systems and computer readable media for L2 redirection in multi-chassis link access group (LAG) environments are described. In some implementations, the method can include determining, at a core switch, a failure of a link in a split multi-link trunk (SMLT), and building, at the core switch, a table mapping each destination media access control (MAC) address to an incoming split multi-link trunk port. The method can also include sending, from the core switch, a link layer discovery protocol (LLDP) redirect message on a per-destination MAC address and per-source access switch basis. The method can further include maintaining a same mapping for each MAC address not hashed to a cluster peer with the failed link or being mapped to a non-inter switch trunk (IST) port.
