Abstract
A system for providing explicit routing functions in a connectionless network. A specific router selects a path through the connectionless network to a destination. Explicit routing advertisements are generated by the specific router and contain information regarding the selected path. Routing state is installed according to information contained in the explicit routing advertisements. The explicit routing advertisements are forwarded to each next hop router. Each next hop router installs routing state, generates the explicit routing advertisement, and forwards the explicit routing advertisement to further propagate the routing information.
