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 Link State Advertisement (LSA) is received from a first router in a network at a second router in the network. The LSA advertises an address of an interface of the first router. The second router determines whether the LSA includes a transit-only identification that indicates the interface of the first router is a transit-only interface. If the LSA does not include a transit-only identification, the second router installs the advertised address of the interface of the first router in a Router Information Base (RIB) of the second router. If the LSA does include a transit-only identification, the second router declines to install the advertised address of the interface of the first router in the RIB of the second router.
摘要翻译：在一个实施例中，在网络中的第二路由器处从网络中的第一路由器接收链路状态通告（LSA）。 LSA通告第一个路由器的接口地址。第二个路由器确定LSA是否包括仅表示第一个路由器的接口的只有传输的标识才是传输专用接口。如果LSA不包含传输标识，则第二路由器将路由器信息库（RIB）中第一个路由器接口的通告地址安装在第二个路由器上。如果LSA确实包含只有传输标识，则第二个路由器拒绝在第二个路由器的RIB中安装第一个路由器接口的通告地址。

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.
摘要翻译：本发明的一个示例性实施例提供了一种涉及在不那样的子区域（NSSSA）边界路由器上的LSA的选择性过滤的过程。在一个实施例中，边界路由器从NSSSA内部的另一个路由器接收LSA，该LSA可能位于分层网络设计模型的接入层中，并且可能使用OSPF作为其IGP。如果LSA为Type 1，并且包含子网路由或转发地址，则边界路由器会将其泛洪到邻近路由器，而不管它们是否位于NSSSA内。如果LSA为Type 7并且包含主机地址，则如果相邻路由器位于NSSSA内，则边界路由器会将其洪泛到邻近路由器，如果相邻路由器在NSSSA之外，则过滤LSA，例如OSPF区域在分层层次的网络设计模型中。
