Abstract: Implementations generally relate to synchronizing peer nodes in networks. In one embodiment, a method includes generating a data sequence number. The method also includes associating the data sequence number with a data item. The method also includes sending the data item and the data sequence number to each peer node of a plurality of peer nodes. The method also includes determining if an acknowledgment has been received from each peer node, wherein each acknowledgment indicates the peer node that sent the acknowledgment and indicates the data sequence number. The method also includes resending the data item and the data sequence number to one or more peer nodes based on a predetermined policy.

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.
