I presume you mean how to get all the weird tools it requires in place?

This is all the things we build on the worker:

https://github.com/linux-netdev/nipa/blob/main/deploy/contest/remote/worker-setup.sh

For mcast routing you only need a handful of those (mtools, smcroute,
ndisc6?), but we don't really track which is needed where :S

Ideally we'd use some image building to compose this automatically..
