The test is not consistently passing. Does not seem to be an issue with the timing.

in the original topotest this is a "negative" check, it checks the route does NOT exist — need to do something similar here.

Good approach would be:

  1. wait for some other route to check the BGP session is up
  2. then check default route is empty/absent

… so this wait is not long enough for the 10s above.

⇒ shorten the 10s above, and make this down here maybe 15s (there is some additional delay, probably from internal BGP timers) ⇒ then it should work

Using bgpd here makes the test a little bit faster (or use less CPU)
