Listen to kernel routing events in real time and verify route changes quickly. 18.06.2026 | reading time: 2 min routel is a small iproute2 utility that listens to the kernel's netlink routing socket and prints route events, letting the administrator watch route additions and deletions in real time. Monitor route changes interactively Start `routel` in one terminal and add a route in another to see the kernel event; example demonstration: ```bash sudo routel # in another terminal sudo ip route add 10.99.99.0/24 via 192.168.1.1 ``` You will observe a RTM_NEWROUTE message with route attributes printed by `routel`, confirming the kernel accepted the route. Use cases that prove value Use `routel` to spot route flaps during troubleshooting, to validate scripts that manipulate routes, and to watch dynamic routing daemons while you inject test routes; it gives a raw kernel-level view you can trust when userland tools disagree. When routel meets other tools Pair `routel` with `ip route show` to inspect the full table, with `ip monitor` to watch multiple netlink families at once, and with `tcpdump` to correlate routing events with protocol traffic on the wire for deeper analysis. Where to go next routel gives a concise, faithful stream of kernel routing events and is ideal for hands-on debugging; deepen your networking and netlink knowledge to automate checks and alerts, and consider focused exam preparation like CompTIA Linux+ or LPIC-1 with bitsandbytes.academy.
