摘要： The present disclosure describes message forwarding in a network where Virtual Local Area Networks (VLANs) are deployed over geographically dispersed sites. The network comprises a first aggregation layer device at a first site and second first aggregation layer device at a second site. The first aggregation layer device learns Media Access Control (MAC) address information received from the second aggregation layer device. The MAC address information includes: a VLAN identifier (ID), an aggregated MAC address and an aggregated MAC address mask configured at the second site. When receiving a message addressed to the VLAN ID and a destination MAC address, the first aggregation layer device searches for the MAC address information based on the VLAN ID and destination MAC address and forwards the message to the second aggregation layer device according to the MAC address information. The destination MAC address belongs to the same MAC address segment as the aggregated MAC address and searching for the MAC address information comprises mask matching based on the aggregated MAC address mask.
摘要翻译：本公开描述了在虚拟局域网（VLAN）部署在地理上分散的站点上的网络中的消息转发。该网络包括第一站点处的第一聚合层设备和第二站点处的第二第一聚合层设备。第一聚合层设备学习从第二聚合层设备接收到的媒体访问控制（MAC）地址信息。 MAC地址信息包括：在第二站点配置的VLAN标识（ID），聚合MAC地址和聚合MAC地址掩码。当接收到发往VLAN ID的消息和目的MAC地址时，第一聚合层设备根据VLAN ID和目的MAC地址搜索MAC地址信息，并根据MAC地址将报文转发给第二聚合层设备信息。目的MAC地址属于与聚合MAC地址相同的MAC地址段，搜索MAC地址信息包括基于聚合MAC地址掩码的掩码匹配。
