First of all, I am very thankful for your help!
I tried to finish the other tables, could you maybe tell me if I am right?
|Step | Router A |
0 | [ (0,A) (/,/) (/,/) (/,/) ]
1 | [ (0,A) (2,B) (1,C) (/,/) ]
2 | [ (0,A) (2,B) (1,C) (2,C) ]
|Step | Router B |
0 | [ (/,/) (0,B) (/,/) (/,/) ]
1 | [ (2,A) (0,B) (4,C) (/,/) ]
2 | [ (2,A) (0,B) (3,A) (5,C) ]
3 | [ (2,A) (0,B) (3,A) (4,A) ]
|Step | Router C |
0 | [ (/,/) (/,/) (0,C) (/,/) ]
1 | [ (1,A) (4,B) (0,C) (1,D) ]
2 | [ (6,B) (3,A) (0,A) (1,D) ]
|Step | Router D |
0 | [ (/,/) (/,/) (/,/) (0,D) ]
1 | [ (2,A) (0,B) (1,C) (0,D) ]
2 | [ (2,C) (4,C) (1,C) (0,D) ]
3 | [ (6,C) (3,C) (1,C) (0,D) ]
I have no idea why I have so much trouble with such a basic task I guess X-X
