Hi,

The following cisco webpage explains different regular expressions.
http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_command_reference_chapter09186a00800ca655.html

>From what I worked in the isp world,
^701$ matches routes with AS number 701 only in the AS-PATH
701$ matches routes end with 701, such as 1234 701, 234 345 701, etc
_701$ matches routes end with 701, I would say it's same as 701$
_701_ matches routes that have 701 anywhere in the AS-PATH

Hope this helps.

Xueyan
