Routing protocol processing intermediaries for cloud computing environments

A system, comprising:

• one or more computing devices;
• wherein the one or more computing devices include instructions that upon execution on or across the one or more computing devices:
• establish, by a routing protocol processing intermediary configured within a cloud computing environment, communication sessions of a dynamic routing information exchange protocol with a plurality of network components, wherein at least one network component is located within the cloud computing environment and at least one other network component is located external to the cloud computing environment;
• receive, at the routing protocol processing intermediary via the communication sessions, routing update messages formatted according to the dynamic routing information exchange protocol from the plurality of network components, wherein the routing update messages comprise reachability information;
• analyze, by the routing protocol processing intermediary, the routing update messages including the reachability information to determine one or more routing table modifications;
• invoke, by the routing protocol processing intermediary, one or more programmatic interfaces of the cloud computing environment to update one or more routing tables within the cloud computing environment according to the one or more routing table modifications based on the analysis;
• and
• propagate, by the routing protocol processing intermediary, at least a subset of routing information indicated in the routing update messages to individual ones of the plurality of network components.
