摘要： A method for communicating packets in a network environment is provided that includes receiving a packet at a network element and identifying a sequence number included in the packet that correlates to awareness information associated with one or more adjacent network elements. A table included in the network element may be updated in order to account for the awareness information included within the packet that has not been accounted for by the network element. In cases where the awareness information included in the packet has already been accounted for, the packet may be ignored.

摘要： Techniques for sending data in a packet-switched communications network include determining multiple subsets of adjacent network nodes of the network. The adjacent network nodes communicate without intervening network nodes with a particular network node through an interface on the particular network node. Each subset includes multiple adjacent network nodes. Subset definition data is sent through the interface. The subset definition data indicates which adjacent network nodes belong to which subset. Data for fewer than all adjacent network nodes in all subsets are sent by including, in a multicast data packet sent over the interface with a multicast destination address, subset identifier data that indicates a particular subset. When such data is received by a node, it is discarded unless the subset identifier matches the receiving node's subset identifier. Among other effects, this allows routing messages to be more efficiently sent to better performing neighboring network nodes.
摘要翻译：在分组交换通信网络中发送数据的技术包括确定网络的相邻网络节点的多个子集。相邻的网络节点通过特定网络节点上的接口与特定的网络节点通信而无需中间网络节点。每个子集包括多个相邻的网络节点。子集定义数据通过接口发送。子集定义数据指示哪些相邻网络节点属于哪个子集。通过在通过接口发送的多播数据分组中包括指示特定子集的子集标识符数据，包括在所有子集中比所有相邻网络节点少的数据。当节点接收到这样的数据时，除非子集标识符与接收节点的子集标识符相匹配，否则丢弃该数据。除此之外，这使得路由消息更有效地发送到更好地执行的相邻网络节点。

摘要： An apparatus for communicating packets in a network environment is provided that includes a first network element that includes a first neighbor list, the first network element being coupled to a second network element and a third network element. The first network element is operable to receive a second neighbor list from the second network element and a third neighbor list from the third network element. The first network element is further operable to determine one or more overlaps provided by the second and third neighbor lists when compared to the first neighbor list, the first network element relaying an update that it receives based on the one or more overlaps.

摘要： In one embodiment, a method includes sending an adjacency discovery message 1 from a local router over a direct link to a first neighbor router. An adjacency discovery message is not forwarded and includes a repair address. The repair address indicates the local router but is not advertised as reachable over the direct link. An outbound routing update message is sent to a different second neighbor router. The outbound routing update message is forwarded and includes reachability data that indicates the repair address is reachable. A payload of an inbound tunneled packet received at the local router and directed to the repair address is forwarded based on a destination indicated in the payload.

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： A static neighbor configured network device is configured with a static neighbor feature including a static neighbor list of network devices. The static neighbor configured network device is in a network segment that includes a dynamically configured network device. The static neighbor configured network device receives a multicast packet from the dynamically configured network device. It is determined if the dynamically configured network device is included in the static neighbor list of the static neighbor configured network device. The multicast packet is accepted if the dynamically configured network device is found in the neighbor list for the static neighbor configured network device. Also, adjacency for the static neighbor configured network device is not lost with any other currently adjacent network devices when the multicast packet is received.
