BGP masks are patterns used for BGP path matching BGP masks are patterns used for BGP path matching
(using <cf>path &tilde; |2 3 5 *|</cf> syntax). The masks (using <cf>path &tilde; [= 2 3 5 * =]</cf> syntax). The masks
resemble wildcard patterns as used by UNIX shells. Autonomous resemble wildcard patterns as used by UNIX shells. Autonomous
system numbers match themselves, <cf/*/ matches any (even empty) system numbers match themselves, <cf/*/ matches any (even empty)
sequence of arbitrary AS numbers. For example: sequence of arbitrary AS numbers. For example, if <cf>bgp_path</cf> is 4 3 2 1, then:
<tt>|4 3 2 1| &tilde; |? 4 3 *|</tt> is true, but <tt>bgp_path &tilde; [= * 4 3 * =]</tt> is true, but
<tt>|4 3 2 1| &tilde; |? 4 5 *|</tt> is false. <tt>bgp_path &tilde; [= * 4 5 * =]</tt> is false.
There is also old syntax that uses / instead of | and ? instead of *. There is also old syntax that uses / .. / instead of [= .. =] and ? instead of *.
