Dear Mr. Lammle,
On page 441 regarding the result of "sh ip eigrp topology", there are more than 1 "feasible distance" (FD) for each line:
- One is at "FD is ...". For eg. FD is 2172416
- The other one is the first number in the parentheses. For eg. (2195456/281600)
As what you explained on the same page, the first FD is the best metric. While the second is the metric of a particular path.
So:
- If there is only 1 route to a remote host, the first FD and the second FD must be the same.
- If there are more than 1 routes (feasible successors) to a remote host, the first FD is equal to the smallest FD (successor) among all routes.
However, this is not true as what displayed in page 441 for some line.
For eg. P 10.1.10.0, P 10.1.7.0, P 10.1.6.0
Did I miss any part or understand wrongly?
Thanks,
Nguyen.
