tutorial: topology source host missing causes [email protected]…

… to crash (#4619) Hi, I've tried to setup the freestanding SCION network as per the [tutorial](https://docs.scion.org/en/latest/tutorials/deploy.html) and ran into a few issues: Using the default topology files from the website, the scion-router service always crashes because of an invalid source IP (see screenshot below): ![image](https://github.com/user-attachments/assets/cef3fa72-a945-438f-ac31-1bc535da2a44) @tobiasmoldan realized that this can be resolved by adding the source IP (or host name) to the local field in the topology: `"underlay": { "local": "scion01:50012", "remote": "scion02:50012" },` Secondly, I was wondering if all ASes need to be up and running for the network to be fully functional? I have set up and configured scion01 and scion02 as per the tutorial. All services (daemon, router, control, dispatcher) are active and there is a direct link between the two VMs. The machines are pingable (via normal ICMP), however, there is no reachability via SCMP. I assume that, even without scion03-05, they should have connectivity? I got scion addresses for scion01 and scion02 respectively, `42-ffaa:1:1,127.0.0.1` `42-ffaa:1:2,127.0.0.1` and I have generated the certificate material on scion01 and shared it with scion02. Is there anything I'm missing - e.g., does path exploration need to be triggered somehow or should it happen automatically? Thanks a lot for your help on this!
