[irrtoolset]Error: badly formed AS_path filter

[Jason Lixfeld <]

I'm not sure what I'm missing here.  When I pass the following through 
RtConfig, I get the above error.  As per the man pages, RFC2622 states: 
 "An AS-path regular expression can be used as a policy filter by 
enclosing the expression in ‘<’ and ‘>’.  An AS-path policy filter 
matches the set of routes which traverses a sequence of ASes matched by 
the AS-path regular expression."  I read that as meaning that my 
RtConfig line which reads @RtConfig aspath_access_list filter <AS577> 
should work fine.  I'm using 577 as an example just to test things out. 
 I'm not peering with 577 and have no relationship with them, however 
that shouldn't prevent me from being able to generate an as-path 
access-list using their information, should it?
