摘要： In one embodiment, a network device may receive an mtrace query, where the mtrace query identifies two or more multicast routing paths. The network device may generate two or more mtrace requests using at least a portion of information obtained from the mtrace query such that each of the two or more mtrace requests identifies a different one of the two or more multicast routing paths. The network device may send each of the two or more mtrace requests via a different one of the two or more multicast routing paths. The network device may then receive at least one response including information pertaining to the two or more multicast routing paths.

摘要： Disclosed are methods and apparatus for flooding link state packets or packet data units (LSP's) from a first node to one other LSP receiving node, where the LSP's are flooded in an order that is related to relative costs of various paths emanating from the first node. That is, the first node sends its own LSP first since the first node has no cost relative to itself. The first node then sends other LSP's that are associated with a plurality of other LSP sending nodes that have previously flooded their LSP's to the first node, and these other LSP's are sent by the first node to the other LSP receiving node in an order related to the relative costs associated with the paths from the first node to each of the other LSP sending nodes which had previously sent the other LSP's to the first node.
摘要翻译：公开了用于将链路状态分组或分组数据单元（LSP）从第一节点扩展到另一个LSP接收节点的方法和装置，其中LSP以与从第一节点发出的各种路径的相对成本相关的顺序淹没。也就是说，第一个节点首先发送自己的LSP，因为第一个节点相对于自身没有成本。然后，第一节点发送与先前已经将其LSP扩充到第一节点的多个其他LSP发送节点相关联的其他LSP，并且这些另外的LSP由第一节点以与其相关的顺序发送到另一个LSP接收节点与从先到先发送其他LSP到第一节点的其他LSP发送节点的第一节点到每个其他LSP发送节点的路径相关的相对成本。

摘要： Disclosed are methods and apparatus for handling Link State Packets (LSPs) sent between processing nodes within a computer network. At a first node, an LSP sent by a second node is received. The received LSP specifies connectivity information regarding the second node. It is then determined whether one of two conditions is met: either the received LSP is an updated LSP even though it appears older and a corresponding stored LSP fails authentication, or the received LSP fails authentication and it appears newer. If it is determined that one of these conditions is met, as well as purging criteria, then updating procedures are then performed on the LSP information that is maintained by the first node, where the LSP information was originally obtained from a corresponding LSP sent by the second node.

摘要： In one embodiment, a first Edge Device may join a multicast group via a multicast router, wherein the first Edge device is in a first site of a network and the multicast router is in a second site of the network. The first Edge Device may ascertain an existence of both a first multicast source in the first site of the network and a second multicast source in the second site of the network. The first Edge Device may select the first multicast source as a multicast source from which to receive multicast data for the multicast group. The first Edge Device may notify the second multicast source in the second site of the network that the first Edge Device is not interested in receiving multicast data for the multicast group from the second multicast source.
