Does OSPF determine routes based on LSA Type? For example, if a Router has received two routing updates referring to the same IP subnet from (1) an Intra-Area route, received from an OSPF peer in Area 0 and (2) an External route received from an ASBR redistributing routes into Area 0
how will the Router make its selection?
I am specifically concerned in the situation where you have an OSPF area interconnecting into another AS at two points. Could this scenario result in sub-optimal routing due to a Router sending intra-area data via the other AS (ie. a routing loop being formed resulting in sub-optimal routing).
Are there any whitepapers which explain this in a little more detail?
Interesting that there seems to be conflicting points of view on this matter. Your view confirms what I thought, but I'd appreciate it if you knew of a reference resource which states it just to stifle any further debate on this matter (I did a search on Cisco's site prior to making this post, but couldn't find anything specific)
