Re: OSPF Distance Command .!

Gents, a little search over GS archives would second Bryan's point! This
issue hunted me down in my first attempt!

While some have even gone to TAC, others have tried bugging it! But from the
research I carried out a while ago, my conclusion is you are not to use AD
to influence prefix selection WITHIN the same routing protocol - use metric
instead! BETWEEN 2 or more routing protocols, use AD.

Otherwise, you are in for a long, unreliable and incoherent exercise.
