Subject: RE: eigrp distance XX setting...
It sets the distances based on the route and the source of the
routing update. The access list matches the route, the address and
wildcard pair match the source of the update. You can find the source
of the update for route w.x.y.z by looking at the "show ip route
w.x.y.z" output; it is contained in the "from a.b.c.d" field. Note that
this configuration *does not* apply to external EIGRP routes.
