Usage guidelines
BGP routing updates contain an AS_PATH attribute field that identifies the ASs through which the routes
have passed. An AS path regular expression, for example, ^200. *100$, matches the AS_PATH
attribute that starts with AS 200 and ends with AS 100. For the meanings of special characters used in
regular expressions, see Fundamentals Configuration Guide.
Examples
# Create AS path list 1 to permit routes whose AS_PATH attribute starts with 10.
<Sysname> system-view
[Sysname] ip as-path 1 permit ^10
