Save configuration

While doing the project, students may need to save their router and switch configurations (e.g., to submit it at the end of the project). When building the mini-Internet, a script called save_configs.sh is automatically generated and aims at saving all the router and switch configurations into a zip file. There is one save_configs.sh script for each group, which is available in the SSH proxy container of the corresponding group (use ./save_configs.sh). Students can then download the zip file to their local machine (e.g., using scp).

Restore configuration

A complementary script restore_configs.sh is also available and restores a router's configuration (or all routers') from a saved configuration. Reloading a configuration of a switch is not supported at the moment.

Restarting ospfd

Students may encounter the message For this router-id change to take effect, save config and restart ospfd when configuring a router. The restart_ospfd.sh script deletes and reinstalls the OSPF configuration running on a given router. Deleting and reinstalling the OSPF configuration effectively restarts ospfd and will cause the new router-id to take effect.
