Abstract: In an embodiment, a method is provided at which it is used in a device. In this method, a logical identifier assigned to the device is identified and additionally, a mesh group identifier identifying a mesh group is identified. The logical identifier and the mesh group identifier are encoded in a routing message, which is used in an inter-domain routing protocol, and this routing message is transmitted to a reflector device in communication with the device. The reflector device is configured to transmit the routing message to a remote device included in the computer network.

Abstract: A method is provided for generating a backup route. Here, a route and a route distinguisher type associated with the route are received and a backup route is generated based on attributes of the route. A particular backup route distinguisher type that is associated with the route distinguisher type is assigned to the backup route. The backup route with the backup route distinguisher type are then advertised. Another method is provided that identifies the backup route. When the route and its route distinguisher type are received from the advertisement, an identification is made as to whether the route distinguisher type is assigned to a backup route. The route may then be designated as a backup route based on the identification.

Abstract: A soft notification technique isolates address family application based errors or events occurring within a routing protocol, such as the Border Gateway Protocol (BGP), used to exchange routing information between a router and its peer router over a BGP session operating on a reliable transport. The technique apportions the session into a plurality of logical subsets, each of which is associated with an address family application (AFI/SAFI) module of a BGP protocol executing on the routers. BGP soft notification messaging is employed to allow the router to notify its peer of an isolated error condition or event associated with an AFI/SAFI module. Isolation of the error/event enables restart (“soft reset”) of only the associated AFI/SAFI module, thereby obviating the need to reset or terminate the entire BGP session and reliable transport between the router and peer. Notably, soft reset of the module occurs without disrupting services provided by other AFI/SAFI modules of the BGP protocol.

Abstract translation: 软通知技术隔离在路由协议（如边界网关协议（BGP））中发生的地址族应用程序错误或事件，用于通过在可靠传输上运行的BGP会话在路由器与其对等路由器之间交换路由信息。 该技术将会话分配到多个逻辑子集中，每个逻辑子集与在路由器上执行的BGP协议的地址族应用（AFI / SAFI）模块相关联。 使用BGP软通知消息传递来允许路由器通知其对等体与AFI / SAFI模块相关联的隔离的错误状况或事件。 隔离错误/事件只能使相关的AFI / SAFI模块重新启动（“软复位”），从而避免重置或终止整个BGP会话以及路由器和对等体之间的可靠传输。 值得注意的是，模块的软复位不会中断BGP协议的其他AFI / SAFI模块提供的服务。
