Yes, that's probably the best solution, if you can trust your PPP
software to reliably bring the link layer down when there's a problem.

One caveat: make sure that your PPP software installs routes with a proper
protocol number; Babel will refuse to redistribute routes unless they
carry a protocol number.

Or you might just run both babel and babel-pinger on the PPPoE endpoint,
pointing babel-pinger at the other end of the PPPoE tunnel.
