Abstract: The following description is directed to configuring gateways in computer networks. For example, a method includes receiving a first request from a client associated with a configurable network. The first request can request associating a set of network addresses assigned to the configurable network to a gateway. A second request can be received from a client associated with the gateway. The second request can request accepting the association of the first request. It can be determined that the set of network addresses do not overlap with a network address space that is accessible using the gateway. Routing information can be generated for the gateway. The generated routing information can be used to configure the gateway for forwarding network packets between the client private network and the configurable network.

Abstract: Technologies are provided for expanding computer network route advertisements. A route expansion server can be configured to receive route advertisements from a router, generate an expanded route advertisement that includes additional network route information, and transmit the expanded route advertisement to another router. The route expansion server can receive a route advertisement from a network zone edge router, comprising a network address prefix. The route expansion server can look up one or more additional network address prefixes associated with the edge router and generate an expanded route advertisement message that indicates that the edge router is a potential next hop for the network address prefix and the one or more additional network address prefixes. The route expansion server can transmit the expanded route advertisement message to another router. In at least some embodiments, the route expansion server can generate different expanded route advertisement messages for different routers.

Abstract: A physical interconnect having multiple virtual paths is coupled between network devices of independent networks operated by different entities. In one aspect, the interconnect is monitored so that the entities can simultaneously and separately monitor network traffic being exchanged across the interconnect. Each entity can be assigned two virtual paths through the interconnect to pass network traffic through their network device, over the interconnect, through a network device of the other entity, back over the interconnect link and back through their network device. The network devices can be configured to loop back network packets using a variety of loopback configurations. Hardware policers that monitor capacity usage of the virtual paths can also be tested.
