package FS::part_export::router;
=head1 FS::part_export::router
This export connects to a router and transmits commands via telnet or SSH.
It requires the following custom router fields:
=over 4
=item admin_address - IP address (or hostname) to connect
=item admin_user - username for admin access
=item admin_password - password for admin access
=back
The export itself needs the following options:
=over 4
=item insert, replace, delete - command strings (to be interpolated)
=item Prompt - prompt string to expect from router after successful login
=item Timeout - time to wait for prompt string
=back
(Prompt and Timeout are required only for telnet connections.)
