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
system numbers match themselves, <cf/?/ matches any (even empty)
sequence of arbitrary AS numbers (<cf/*/ hasn't been chosen, because
<cf>/*</cf> starts a comment). For example:
<tt>/4 3 2 1/ &tilde; /? 4 3 ?/</tt> is true, but
<tt>/4 3 2 1/ &tilde; /? 4 5 ?/</tt> is false.
system numbers match themselves, <cf/*/ matches any (even empty)
sequence of arbitrary AS numbers. For example:
<tt>|4 3 2 1| &tilde; |? 4 3 *|</tt> is true, but
<tt>|4 3 2 1| &tilde; |? 4 5 *|</tt> is false.
There is also old syntax that uses / instead of | and ? instead of *.
