Thanks Guys, According to http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094aaa.shtml#diffstubs type 5's are denied at stub. According to RFC standard: "As specified in Section 12.4.3, Type 4 summary-LSAs (ASBR-summary-LSAs) are never originated into stub areas."
So the RFC reflects lab results, but Cisco disagrees :) Kim Robert S Wyzykowski wrote: > Type 4 sla is "where to go" for the next hop of the type 5 sla.
