Yes, the second one.
If there's two routes to the same (remote) destination, one a type1 and the
other a type2 (and they have different forward metrics) they type 1 will be
preferred because it is also indicating the intra-AS cost to the route. The
type 2 is only carrying the inter-AS cost.
If there's 2 routes: a type1 and a type2 and the metric's the same (ie both
sources of the routes must be the same ASBR) then the type 2 route will be
preferred.
(I'm happy for anyone to jump in here and tell me I'm wrong!!)

Subject: which one of halabi's statements is correct?
sorry to sound convoluted, but the following is the best way to word the
question:
halabi says:
"A type 1 route is always preferred over a type 2 route for the same
destination"
on the same page below, he says
"Type 2 routes are preferred over type 1 routes in case two same cost routes
exist to the destination. "
are these contradictory statements or is it the fact that if two equal cost
routes (e..g, w/ the same forward metric) to the same net, that the type 2
route
will be preferred
BUT if two UNEQUAL cost routes (e..g, w/ different forward metrics) exist,
that
the type 1 route will be preferred?
