Path from Milan
Milan's routing table
How Milan reaches every other city. Cost is the OSPF metric: one per hop.
| City | Next router | Cost | Sites |

Remote access over WireGuard
Remote PCs connect through an encrypted WireGuard tunnel that ends on the Milan router (wg0, 10.9.0.1). Milan announces 10.9.0.0/24 in OSPF, so every city can reach them.
| Device | Address | Tunnel | Last heard from | Traffic | Ping from Milan site 1 |

Sites reachable from Milan
Every 15 seconds the PC in Milan site 1 pings the PC (.2) and the switch (.7) of all 24 sites.

How this page works
The network runs on a cloud server: 54 containers built from one Python file. Every 15 seconds a script runs show commands, pings and traceroutes inside the lab and saves the results. This page only reads them, so nothing here can change the network.
Remote PCs join over WireGuard and appear on the map, tunnelled into Milan. Their home addresses and keys never reach this page.
To see failover, the Milan to Naples cable can be cut. Within seconds OSPF sends Milan's traffic for Rome the long way round through Turin, and this page shows the new path on its next refresh.
