Hi Jay, Not only would doing so violate the spec and potentially cause interop issues with other implementations, it would also likely be tough to implement. The LSA's that can be summarized are all LSA's that the router itself generates. I imagine it is quite easy to apply some logic within the generation process that allows the ABR to make some LSA population decisions for type 3's and 5's (in the NSSA ABR role) as it generates them. Creating hooks into the type 5 flooding process for complete regeneration of the LSA would be a challenge, plus would lead to other nastiness in multivendor environments.
