Route advertisement management using tags in directly connected networks

A system, comprising:

• a provider network comprising networking devices and computing devices configured to implement one or more public services;
• an endpoint router of the provider network configured to connect to a client network of a client of the provider network via a private dedicated physical connection;
• wherein the networking devices are configured to:
• receive routing information from the client network, via the private dedicated physical connection, comprising:
• a route for a client device of the client network to be configured to access the one or more public services of the provider network;
• and
• a corresponding routing scope value for the route, wherein the corresponding routing scope value conforms to a schema published by the provider network, and wherein the schema comprises different routing scope values to indicate different portions of the provider network through which client device routes are to be advertised;
• and
• propagate the route for the client device within the portion of the provider network as indicated by the corresponding routing scope value.

A method, comprising:

• receiving routing information from a client network, via a private dedicated physical connection between the client network and a provider network, wherein the provider network comprises networking devices and computing devices configured to implement one or more public services, and wherein the routing information comprises:
• a route for a client device of the client network to be configured to access the one or more public services of the provider network;
• and
• a corresponding routing scope value for the route, wherein the corresponding routing scope value conforms to a schema published by the provider network, and wherein the schema comprises different routing scope values to indicate different portions of the provider network through which client device routes are to be advertised;
• and
• propagating the route for the client device within a portion of the provider network as indicated by the corresponding routing scope value.

A system, comprising:

• a provider network comprising networking devices and computing devices configured to implement one or more public services;
• an endpoint router of the provider network configured to connect to a client network of a client of the provider network via a private dedicated physical connection;
• wherein the endpoint router is configured to:
• receive routes for resources of the one or more public services of the provider network via the one or more of the networking devices of the provider network;
• determine according to a schema published by the provider network, and based on an origin of the routes and a location of the endpoint router in the provider network, respective corresponding routing scope values for the routes;
• and
• provide to the client network, via the endpoint router, routing information comprising:
• the routes for the resources of one or more public services of the provider network;
• and
• the determined respective routing scope values indicating respective portions of the provider network wherein the resources that correspond with the one or more routes are located.
