vtysh is integrated shell of Quagga software.
To use vtysh please specify —enable-vtysh to configure script. To use PAM for authentication use —with-libpam option to configure script.
vtysh only searches /etc/quagga path for vtysh.conf which is the vtysh configuration file. Vtysh does not search current directory for configuration file because the file includes user authentication settings.
Currently, vtysh.conf has only two commands.
