摘要： The present invention elects an area border router from a plurality of potential area border routers by determining a full set of all areas attached to a router. A determination is made as to a full set of area pairs from the determined full set of areas. Routers are identified in a first area of the determined full set of areas that are reachable through an intra-area route in the first area, and routers are identified in a second area of the determined full set of areas that are reachable through an intra-area route in the second area. If there is a router that is unreachable through either an intra-area route in the first area or an intra-area route in the second area, then declare the first router to be an area border router, else new first and second areas are selected.

摘要： A method and apparatus for sharing routing information include receiving first domain data that indicates domains of a first mobile router. A domain is a collection of routers that share uniform routing information at a particular level of detail. An inbound data packet is received from a second mobile router over a particular link. The inbound control plane packet lists second domain data that indicates domains of the second mobile router. The first domain data and the second domain data together include multiple domains. A particular domain is automatically selected from the first domain data and the second domain data. The second mobile router independently selects the same particular domain. The particular link is assigned to the particular domain; and routing information for the particular domain is shared between the first mobile router and the second mobile router over the particular link.

摘要： A technique dynamically configures and verifies routing information of broadcast networks using link state protocols in a computer network. According to the novel technique, a router within the broadcast network receives a link state protocol routing information advertisement from an advertising router, e.g., a designated router or other adjacent neighbor. The router learns of a next-hop router (“next-hop”) to reach a particular destination from the advertisement, and determines whether the next-hop is located within the same broadcast network (e.g., subnet) as the designated router. If so, the router further determines whether the next-hop is directly addressable (i.e., reachable), such as, e.g., by checking for link adjacencies to the next-hop or by sending request/reply messages (e.g., echo messages or “ping” messages) to the next-hop. In the event the next-hop for the destination is not directly addressable by the router (e.g., no adjacency or reply), the router installs a route to the destination via the designated router. Otherwise, the router installs a route to the destination via the next-hop.
摘要翻译：技术使用计算机网络中的链路状态协议来动态地配置和验证广播网络的路由信息。根据该技术，广播网络内的路由器从广告路由器（例如，指定路由器或其他相邻邻居）接收链路状态协议路由信息广告。路由器学习下一跳路由器（“下一跳”）从广告到达特定目的地，并且确定下一跳是否位于与指定路由器相同的广播网络（例如，子网）内。如果是这样，则路由器进一步确定下一跳是否可直接寻址（即可达到），例如通过检查下一跳的链路邻接或通过发送请求/应答消息（例如，回波消息或“ ping“消息）到下一跳。在目的地的下一跳不能由路由器直接寻址的情况下（例如，没有邻接或回复），路由器经由指定的路由器安装到目的地的路由。否则，路由器将通过下一跳安装到目的地的路由。

摘要： In one embodiment, a method includes setting a re-flood time to a non-zero first value. Update data that indicates a change to link data is received over a network interface from an updating node of multiple nodes on a multi-access segment connected to the interface. The change is to link data that indicates links on the updating node. It is determined whether an acknowledgment message is not received within the re-flood time from a particular node of the multiple nodes. If an acknowledgment message is not received within the re-flood time, then a multicast packet directed to the multiple nodes and including the change to the link data is sent over onto the segment. This method enables rapid response to failure of a primary node designated to ensure reliable flooding of link data.
摘要翻译：在一个实施例中，一种方法包括将重新启动时间设置为非零第一值。通过网络接口从连接到该接口的多访问段上的多个节点的更新节点接收到指示对链接数据的更改的更新数据。更改是链接指示更新节点上的链接的数据。确定在来自多个节点的特定节点的重新洪泛时间内是否未接收到确认消息。如果在重新洪泛时间内没有接收到确认消息，则将指向多个节点并包括对链路数据的改变的组播分组发送到该段上。该方法能够快速响应指定的主节点的故障，以确保链路数据的可靠淹没。
