    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 for communicating packets in a network environment is provided that includes communicating, by a first network element, a first summary update to a second network element. The method further includes receiving a second summary update from the second network element. The exchange of the first and second summary updates achieves adjacency between the first and second network elements. The first and second summary updates include, at least, locally generated state information and a single link state.

    摘要: A method for reducing information being transmitted in a network is provided that includes gleaning routing information being communicated by a first network element, the routing information being stored such that the routing information may be accessed. An adjacency protocol may be executed between the first network element and a second network element that allows for a data exchange between the first and second network elements. The first network element does not communicate the routing information gleaned by the second network element during the data exchange associated with the adjacency protocol.

    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: An example embodiment of the present invention provides a process relating to the selective filtering of an LSA at a not-so-stubby-sub-area (NSSSA) border router. In one embodiment, the border router receives an LSA from another router inside the NSSSA, which might be in the access layer of the hierarchical network design model and which might use OSPF as its IGP. If the LSA is Type 1 and includes a subnet route or forwarder address, the border router floods it to its neighboring routers, regardless of whether they are inside the NSSSA. If the LSA is Type 7 and includes a host address, the border router floods it to a neighboring router if the neighboring router is inside the NSSSA, but filters the LSA if the neighboring router is outside the NSSSA, for example, in an OSPF area in the distribution layer of the hierarchical network design model.
