摘要： A method and computer program product for providing autonomous system interconnect for a first peer device is presented. The method includes producing routing information at a first peer. Next, the first peer device provides a context identifier in the routing information. A context authenticator is also provided in the routing information at the first peer. The first peer then advertises this routing information to a second peer. The first peer only accepts messages from the second peer which include the context identifier and the context authenticator.

摘要： A method and apparatus for performing Layer 2 (L2) interworking is presented. A L2 Protocol Data Unit (PDU) is received at an L2 Switching Entity (SE). The L2 PDU is converted to a normalized Pseudowire (PW) PDU. The normalized PW PDU is then forwarded to a Layer 3 (L3) Routing Entity (RE). The normalized PDU may be in the form of a predetermined L2 protocol or a L2 agnostic protocol.

摘要： A method and apparatus for providing routing protocol support for distributing encryption information is presented. Subnet prefixes reachable on a first customer site in an encrypted manner are identified, as are security groups the subnet prefixes belong to. An advertisement is received at a first Customer Edge (CE) device in the first customer site, the advertisement originating from a Customer (C) device in the first customer site. The advertisement indicates links, subnets to be encrypted, and security group identifiers. The prefixes and the security group identifiers are then propagated across a service provider network to a second CE device located in a second customer site. In such a manner, encryption and authentication is expanded further into a customer site, as customer devices are able to indicate to a service provider network infrastructure and other customer devices in other customer sites which local destinations require encryption/authentication.

摘要： A method, apparatus and computer program product for providing secure multipoint Internet Protocol Virtual Private Networks (IPVPNs) is presented. A packet lookup is performed in order to determine a next hop. A VPN label is pushed on the packet, as is an IP tunnel header. Group encryption through the use of DGVPN is further utilized. In such a manner secure connectivity and network partitioning are provided in a single solution.

摘要： A system provides a request for a policy from a policy server, and receives the policy from the policy server. The policy indicates processing to be applied to a traffic partition passing through the device. The system configures the policy within a routing structure associated with the traffic partition for the policy in the device, and routes a stream of traffic for the routing structure in accordance with the policy for that routing structure.

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).
摘要翻译：路由机制通过分段识别，给定VPN段的策略分配以及使用指示VPN段（子网）的以太网VLAN_ID对每个段进行封装/解封装来提供网络分段保护。消息分组中的封装分段信息标识下一跳采用的路由和转发表。公共路由实例从公共接口接收消息包，并从指示子网（例如，段）的VLAN ID或段标识符中对相应的VRF表进行索引。以这种方式，路由实例接收到入消息包，将入局消息包中的VLAN ID解封装，并从VLAN ID中对相应的VRF和策略ID进行索引，因此在公共子接口上采用公共路由实例，耦合到特定转发设备（例如，VPN路由器）的段（子网络）。
