Multi-Router Routing Audit (BGP / OSPF / VRF)

PRO · free trialRuns in your browser

Audit BGP, OSPF, VRF and interfaces across many router configs at once – like Batfish, but in your browser.

Load configs from many routers (Cisco, Huawei, Nokia SR OS, Juniper). The tool pairs interfaces by subnet into links and cross-checks the whole network – no live access needed.

What it does

MTU mismatch on a link; duplicate IPs across devices
OSPF: area mismatch, or enabled on only one side of a link
BGP: wrong remote-as (vs the other side’s local AS), one-way peering, neighbor IP not found on any device
VRF: duplicate route-distinguisher, route-target exported with no importer (and vice versa)
Per-device summary (vendor, interfaces, local AS, peers, VRFs) + Excel export

How it works

1. Load your dataRouter configs (.txt / .cfg / .conf or a .zip) – one file per router – drag & drop anywhere on the page; the file type is detected automatically.

2. Review the findingsEvery error and warning is clickable and jumps to the exact row, line or parameter, with a proposed fix.

3. Export & shareExcel, PDF and other exports; run history and before / after comparison are kept on your computer.

FAQ

Is my data uploaded to a server?

No. Files are processed in your browser (or by the optional helper app on your own computer). Nothing is stored on our servers.

Do I need to install anything?

No – it is a web app. You can optionally install it as a desktop app from the browser. A small helper app is only needed for tools that must reach your network (ping, port check, auto login).
