Abstract

See full text

Disclosed example routing methods include accessing a control packet originating from a first internal router, translating the destination address of the control packet from a first value to a second value, and identifying a first one of a plurality of outgoing interfaces of a meta-router based on the second value of the destination address, the outgoing interfaces of the meta-router in communication with respective incoming interfaces of a splitter. Disclosed example methods also include forwarding the control packet to the first one of the outgoing interfaces of the meta-router after translating the destination address of the control packet from the second value back to the first value, and routing the control packet from the splitter to an external router based on which one of the incoming interfaces of the splitter receives the control packet from the meta-router.
