From 367deade8a3328e535c0050db657727811a71adf Mon Sep 17 00:00:00 2001 From: "Francisco Blas Izquierdo Riera (klondike)" Date: Wed, 18 Feb 2026 18:24:21 +0100 Subject: [PATCH] Update topology.json The static arp tables in the hosts use the wrong MAC addresses for the routers using 01:00 and 02:00 for router 1 and 03:00 and 04:00 for router 2. If we check the runtime topologies we can see that router 1 has 01:00, router 2 has 02:00, router 3has 03:00 and router 4 has 04:00. Update the host configuration so the MAC address on their packets matches the expected address for the specific router.
