There was a research papre somewhere (although a bit outdated - from 2005),
stating that the optimal value is 75. That was used as the foundation for
the default value of maxas-limit within the Cisco IOS.

I can't find the URL to that paper right now, though ...

And yes, the standards do allow inifinitely long AS paths, but AS path
space is finite, as well as the buffer for communities and other BGP
attributes. A BCP for implementors would be nice to have though ...
