摘要： Systems, methods, and other embodiments associated with logically partitioned networking devices are described herein. One example method includes receiving a message from a common interface. The message comprises a logical partition header (LPH) and a network segmentation header (NSH). The LPH may be associated with a logical partition of a networking device. The NSH is associated with a grouping (e.g., segmentation) of networking devices. The example method may also include forwarding the message to the grouping of networking devices based, at least in part, on the NSH and a virtual route forwarding (VRF) table. Forwarding the message to the logical partition of the networking device based, at least in part, on the LPH.

摘要： Systems, methods, and other embodiments associated with layer two (L2) encryption for data center interconnectivity are described. One example system includes a receive logic to receive an unencrypted L2 switched frame (UL2SF). The UL2SF may include a payload and an L2 header. The example system may also include an encryption logic to selectively encrypt the UL2SF into an encrypted frame if the UL2SF is to be sent through an L2 virtual private network (L2VPN) requiring encryption. The example system may also include a delivery logic that adds a header to the encrypted frame. The header may include data to identify a decryption function to decrypt the encrypted frame and routing information for the encrypted frame. The delivery logic may also provide the encrypted frame to the L2VPN, where the providing includes selectively sending the encrypted frame as one of, a point to point packet, and a multipoint packet.

摘要： One embodiment provides a method to interconnect virtual network segments (VNETs) defined for a local-area network (LAN) infrastructure separated by a wide-area network infrastructure. The technique involves the routing device at the LAN-WAN interconnection points to impose or dispose the VNET-shim, which encodes the VNET-id information in a Layer 4 portion of the packet. In a data plane, a new IP protocol value may be used to signify the presence of the VNET-shim followed by cryptography specific information in an IP packet. In a control plane, the routing protocol is expanded to exchange the routing information along with the VNET information.

摘要： In one embodiment, a technique for selecting a topology, in a multi-topology routing network, based on a source-destination pair of a packet is provided. The packet may be routed on a preferred path of the selected topology. By selecting the same topology for the source-destination pair even if the source and destination addresses are swapped, upstream and downstream traffic may be routed in a symmetrical manner. For some embodiments, a topology may be selected using a hash value that is generated using an algorithm that is commutative with respect to the source and destination addresses.

摘要： A routing mechanism provides network segmentation preservation by route distribution with segment identification, policy distribution for a given VPN segment, and encapsulation/decapsulation for each segment using an Ethernet VLAN_ID, indicative of the VPN segment (subnetwork). Encapsulated segmentation information in a message packet identifies which routing and forwarding table is employed for the next hop. A common routing instance receives the message packets from the common interface, and indexes a corresponding VRF table from the VLAN ID, or segment identifier, indicative of the subnetwork (e.g. segment). In this manner, the routing instance receives the incoming message packet, decapsulates the VLAN ID in the incoming message packet, and indexes the corresponding VRF and policy ID from the VLAN ID, therefore employing a common routing instance over a common subinterface for a plurality of segments (subnetworks) coupled to a particular forwarding device (e.g. VPN router).
