摘要： Each router (22a-22g) in a network is configured for generating router advertisement messages (24a-24c) according to a flooding distance vector routing protocol. Each router (22a-22g) advertisement message (24a-24c) output according to the flooding distance vector routing protocol includes reachability information for at least one destination, and an originating router identifier (26a, 26b) indicating a router having originated the reachability information. If any router receiving the router advertisement message (24a-24c) detects a match between the originating router identifier (26a, 26b) and the corresponding assigned router identifier, the received router advertisement message (24a-24c) is disregarded during calculation of the best paths from the network. If the originating router identifier (26a, 26b) identifies another router, the router floods the received router advertisement message to other ports, and output its own router advertisement message based on the received router advertisement message and that specifies the originating router identifier from the received router advertisement message.

摘要： In one embodiment, a method includes receiving on a first communication link at a local router all routing information at a certain level of detail for each router of multiple routers communicating in a first flooding domain. A measure of distance is determined from a particular router in the first flooding domain to the local router. It is determined whether the measure of distance exceeds a threshold. If the measure of distance exceeds the threshold, then summary routing information with less than the certain level of detail is determined for the particular router. Also, certain routing information is sent over a different second communication link at the local router. The certain routing information includes the summary information for the particular router, and all routing information at the certain level of detail for a subset of routers communicating in the first flooding domain, which subset excludes the particular router.

摘要： An exploration technique allows a router to efficiently determine capabilities and configuration of a neighbor (peer) router. In addition, the technique enables peer routers of an adjacency to negotiate a capability "outside" of a protocol, such as a routing protocol, before a routing session is established between the routers. In this context, the term "outside" of the protocol denotes that there is no field within a protocol packet (message) implementation that can be used to negotiate the capability. Moreover, the inventive technique obviates the need to manually configure a router to support a particular capability and interoperate correctly within a network of routers that both support and are unaware of the capability.
摘要翻译：探索技术允许路由器有效地确定邻居（对等）路由器的能力和配置。此外，在路由器之间建立路由会话之前，该技术使邻接的对等路由器能够协商诸如路由协议之类的协议“外部”能力。在这种情况下，协议中的“外部”一词表示协议包（消息）实现中没有可用于协商能力的字段。此外，本发明的技术避免了手动配置路由器以支持特定能力并且在支持并且不知道能力的路由器的网络内正确地互操作的需要。
