[dev] Babel Admin Distance

All - Renato and I noticed that zebra was not properly handling Admin distance correctly. As part of cleaenup we created this PR: https://github.com/FRRouting/frr/pull/1160 Which has this commit: https://github.com/FRRouting/frr/pull/1160/commits/c710b277cfde65fab8ae071fd... During discussion about this the other night, I guessed at an admin distance of 100 for Babel. In conversation this morning with Don Slice he indicated that a number of 100 might be a bit low as that do we really trust Babel more than OSPF? Do people have opinions on what the Admin Distance should be set too? thanks! donald
