symbol _ to as-path expression alcatel 7750

[Agus Mulya Permana]

dear all,
we are currently converting cisco to alcatel config,
we have problems with regular expression
 if in cisco ^ 77500_ [0-9] * $
what if on Alcatel ?

There are some extra spaces in your example but assuming you want to match an as-path where the first AS must be 77500 and then zero or 1 ASNs after that:

as-path "FOO" expression "77500 .{0,1}"

The regular expression syntax is documented here:

You can use the command "show router bgp policy-test" to test it.
