AS path weirdness



I'm seeing the following in the MRT data from RRC04 at ripe.
http://www.ripe.net/projects/ris/rawdata.html

http://data.ris.ripe.net/rrc04/2009.03/bview.20090320.2359.gz for reference.

I'm not entirely sure what I'm looking at. The reserved AS, 65490
appears in parentheses and I've never seen that in MRT formatted data
and not sure why it's happening.

I'm also not clear on why I see 23456 *and* a 32 bit AS in the path.  Is
 anyone else seeing this or is it something wacky at RRC04?
