Re: Redistribution into OSPF - Type 2

RFC2328 - Section 16.4.6

(d) If the new AS external path is still indistinguishable
                from the current paths in the N's routing table entry,
                select the preferred path based on a least cost
                comparison. Type 1 external paths are compared by
                looking at the sum of the distance to the forwarding
                address and the advertised type 1 metric (X+Y). Type 2
                external paths advertising equal type 2 metrics are
                compared by looking at the distance to the forwarding
                addresses.

Just keep in mind this little nugget though...
