摘要： In one embodiment, an edge router of a local computer network snoops client-server protocol configuration information of a customer-premises equipment (CPE) device. From the snooping, the edge router may identify an Internet Protocol version 6 (IPv6) transition option in place at the CPE device along with associated configuration parameters for the IPv6 transition option. As such, the edge router may then advertise the IPv6 transition option along with associated configuration parameters to one or more border/relay routers of the local computer network to cause the one or more border/relay routers to provision themselves with the IPv6 transition option and associated configuration parameters.

摘要： Systems, methods, and other embodiments associated with any-to-any multicasting in a tunnel based virtual private network (VPN) are described. One example method includes calculating a resolved address for an unknown reverse path forwarding (RPF) neighbor in an any-to-any multicasting route. The resolved address is calculated using next hop resolution protocol (NHRP) resolution. The address is to be resolved based on control plane traffic. The NHRP address resolution is not to affect unicast routing. The example method may also include establishing the any-to-any multicasting route. Since the multicasting route is any-to-any (e.g., spoke-to-spoke), the multicasting route is not required to include a hub in the logical hub-and-spoke network.

摘要： A method in an example embodiment can include polling a first cable modem in a cable network and receiving a first response message from the first cable modem identifying a downstream frequency detected by the first cable modem. The method further includes determining the downstream frequency is split between at least two fiber nodes and determining a cable modem termination system (CMTS) service group topology, where the topology includes the at least two fiber nodes. In specific embodiments, determining that the downstream frequency is split is based on at least the first response message from the first cable modem and a second response message from a second cable modem. In more specific embodiments, the method includes constructing a hybrid fiber-coaxial (HFC) topology map of the cable network based on at least the first and second response messages, where the HFC topology map indicates the CMTS service group topology.
