摘要： MP-BGP VPN infrastructure based on IETF RFC 4364/2547 is used to configure a layer 2 VPN on an IP network. VRFs for the VPN are configured on Ethernet switches and service IP addresses are associated with each configured VRF. The service IP addresses are exchanged to enable VPN traffic to be encapsulated for transport over the IP network. To enable a L2 VPN to be established, a VPN-VLAN ID will be configured for the L2 VPN and import/export route targets for the VPN-VLAN will be set in each VRF and UNI-VLAN included in the VPN. The VPN-VLAN will be announced to all PEs using MP-iBGP with export route targets set for this VPN-VLAN. Once the VPN-VLAN is learned on a logical port, the PE will perform MAC learning on that logical port and treat the logical port as part of the L2 VLAN.

摘要翻译：基于IETF RFC 4364/2547的MP-BGP VPN基础设施用于在IP网络上配置第2层VPN。 VPN的VRF在以太网交换机上配置，服务IP地址与每个配置的VRF相关联。交换服务IP地址，使VPN流量能够被封装以便通过IP网络进行传输。要建立L2 VPN，将为L2 VPN配置VPN-VLAN ID，并在VPN中包含的每个VRF和UNI-VLAN中设置VPN-VLAN的导入/导出路由目标。 VPN-VLAN将使用MP-iBGP向所有PE发布，并为此VPN-VLAN设置导出路由目标。在逻辑端口学到VPN-VLAN后，PE将对该逻辑端口进行MAC学习，并将该逻辑端口视为L2 VLAN的一部分。

摘要： Systems and methods are disclosed of routing data in a network 300 that include classifying incoming data packets 102 using the content of the incoming data packets 102 that remains relatively consistent during a network session with an ingress network processing unit 104. These systems and methods also include ordering the incoming data packets 102 according to at least one internet protocol address comprised within the packet 102, hashing the at least one internet protocol address and the destination port within the packet, and determining a destination service module 222, 224, and 226 for the incoming packet 102 using the ingress network processing unit 104. Through these systems and methods, data can be routed without the need for complete flow tables.

摘要： Nodes on an Ethernet network implement a link state routing protocol. Nodes assign an IP address or I-SID value per VRF and advertise the IP addresses or I-SID values using LSAs. When a packet is to be forwarded on the VPN, the ingress node identifies the VRF for the packet and performs an IP lookup in customer address space in the VRF to determine the next hop and IP address or I-SID value of the VRF on the egress node. The ingress node prepends an I-SID or IP header to identify the VRFs and creates a MAC header to allow the packet to be forwarded to the egress node on the Ethernet network. When the packet is received at the egress node, the MAC header is stripped from the packet and the appended I-SID or IP header is used to identify the egress VRF.
摘要翻译：以太网上的节点实现链路状态路由协议。节点为每个VRF分配IP地址或I-SID值，并使用LSA通告IP地址或I-SID值。当在VPN上转发数据包时，入口节点识别数据包的VRF，并在VRF的客户地址空间中执行IP查找，以确定VRF的下一跳和IP地址或I-SID值出口节点。入口节点添加I-SID或IP头以识别VRF，并创建一个MAC报头，以允许将数据包转发到以太网上的出口节点。当在出口节点处接收到分组时，从分组中剥离MAC报头，并使用附加的I-SID或IP报头来识别出口VRF。

摘要： In a communications network, a cluster switch is provided, where the cluster switch has plural individual switches. An abstraction layer is provided in the cluster switch, such that an interface having a set of ports is provided to upper layer logic in the cluster switch. The set of ports includes a collection of ports of the individual switches. Control traffic and data traffic are communicated over virtual tunnels between individual switches of the cluster switch, where each virtual tunnel has an active channel and at least one standby channel.
