EOS supported two routing protocol implementations: multi-agent and ribd. The ribd routing protocol model is removed starting from the EOS-4.32.0F release. Multi-agent will be the only routing protocol model. Both models largely work the same way though there are subtle differences.

This feature adds support for specifying Resolution Rib Profile as system-connected per-via (next-hop) for static routes. System-connected means that a static route is only resolved if the next-hop is reachable over a connected route. If system-connected is not specified, it means that the static route is resolved if the next-hop is reachable over any kind of route in the routing FIB, including a connected route as well as a tunnel rib.
