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.

Abstract translation: 描述了多机架链路接入组（LAG）环境中用于L2重定向的方法，系统和计算机可读介质。 在一些实现中，该方法可以包括在核心交换机处确定分离多链路中继（SMLT）中的链路的故障，以及在核心交换机处建立映射每个目的地媒体访问控制（MAC） 地址到进入的分离多链路中继端口。 该方法还可以包括从核心交换机向每个目的地MAC地址和每个源接入交换机发送链路层发现协议（LLDP）重定向消息。 该方法可以进一步包括为具有故障链路的群集对等体不被散列的每个MAC地址保持相同的映射或被映射到非交换机间中继（IST）端口。
