The routing half of the CCNP and CCIE blueprints. Articles tagged IP Routing cover static and dynamic routing, redistribution, policy routing and route manipulation on Cisco IOS XE.
Next-hop, exit-interface, and fully specified static routes on Cisco IOS XE, plus default, floating, and host routes. Configured in a live lab with the failure modes shown, including recursion and administrative distance gotchas.

Administrative distance ranks how much a router trusts each source of routing information, and it is the reason a prefix installs via EIGRP when you expected OSPF. Here is the complete default table, the floating static design that depends on it, and a real CML capture of the same prefix...
Read show ip route line by line: which protocol installed each route, the administrative distance and metric, how long the route has been stable, and which interface the packet leaves through, with real captures from IOS XE.
