In the simple case, any static route *in the routing table* is
redistributed if the ``redistribute static'' command is used, and some
filter (set with either ``route-map'' or ``distribute-list out'')
doesn't filter it out.

Whether the static route gets into routing table depends on:

	Whether the next hop address is reachable (if you use
	static route pointing to a next hop)
OR
	Whether the interface is up (if you use static route
	pointing to an interface). 

If one of these is true, an attempt is made to add the route to the
routing table; whether that succeeds depends on the administrative
distance of the route -- a lower administrative distance (the route
is "closer") than a preexisting route will cause the preexisting route
to be overwritten.
