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： A method and apparatus are presented supporting shortest path first (SPF) routing of data packets over a network by establishing link-state data at an router. Link-state data indicates direct links between the router and a different router and establishes an adjacency relationship with the different node. Initial link-state data is stored at a first router. After the initial link-state data is stored, a hello message is received at the first router. The hello message indicates a direct connection with a different second router on one network segment. Based on the initial link-state data, it is determined whether establishing an adjacency relationship with the second router is sufficiently valuable. If not, then an adjacency relationship is not established with the second router in response to the hello message. A shortest path first routing for a data packet traversing the network is determined based on one or more adjacency relationships indicated in link-state data stored at the first router.

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： 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.
