1. setup RIB entries on hosts: C has a route toward B, A A, B has two routes toward B A and C
2. run ping server on B, A, run ping client on A B
3. after 5s: fail link A-B
4. after 5s: recover link A-B
5. after 5s: fail link A-C
6. after 5s: recover link A-C
7. after 5s: stop ping client
8. analyze ping client logs, fail the test case if there is any loss, or RTT is over 100ms for any sequence number
Notes
* to inject a link failure: use iptables to drop UDP packets on the port numbers used by the tunnel; don't destroy face
