[Routing]
	protocol = 'olsrd'   # olsrd | babel | none

Selects which mesh routing daemon VSNES gates and manages inside every container node. Only ONE protocol’s firewall rules and daemon are ever installed — switching protocols (or to none) between runs always converges cleanly, even without a clean stop first. none applies netem channel shaping only, with no routing daemon and no per-pair firewall gating. Missing the [Routing] section defaults to none (with a warning).

Protocols are a small registry in Class/routing.py — see the module docstring (“Adding a routing protocol”) to add one (e.g. an experimental QUIC/DTN router): each entry declares its firewall binary/chain/gating-port and daemon start/stop commands, and Channel.py drives any entry generically.
