In test 10 the tester is giving me an error but my implementation returns the correct weight and the correct next hop.

In the logs for test case 9 I found instances where the cost of an interface was set to 17. According to the RFC no metric can exceed 16, which indicates a bug in the tester.

2018/05/30 03:16:23 To 1.1.3.0 via 0.0.0.0 (next hop)
2018/05/30 03:16:23 To 1.1.4.0 via 1.1.3.2 (next hop)
2018/05/30 03:16:23 To 1.1.5.0 via 1.1.3.2 (next hop)
2018/05/30 03:16:23 To 1.1.2.0 via 1.1.3.2 (next hop)
2018/05/30 03:16:23 Set cost to 17.000000 in graph
2018/05/30 03:16:23 lvns server changed cost to 17
2018/05/30 03:16:23 Routes as reported by d1
2018/05/30 03:16:23 Path from d1 (0) to subnet (1.1.2.0) shouldnt exist
2018/05/30 03:16:23 Shouldnt have a path, but it does

I currently can't run this with go 1.7 installed (Debian stable).

It would be nice if the tester.log would feature additional information except for things like:

2018/05/28 20:37:33 Path from dr1 (0) to subnet (34.78.96.0) isnt ok, weight in graph: 1.000000
2018/05/28 20:37:34 Path from dr1 (0) to subnet (34.78.96.0) isnt ok, weight in graph: 1.000000

My suggestion would be to write in there whenever an interface gets taken offline or online and when costs changes. That way it will become more debuggable.

Btw. thanks for the tester! You're awesome!

According to my logs, the complex2 test case should succeed, but my program fails test case 6. I have no idea why this occurs.

Maybe the path chosen by my implementation is different, but of the same cost..?
