For ppp-interfaces, there are directories, executable files from which are also run at different phases of connection establishment. But, if, for example, ethernet interfaces, these scripts must be located in the /etc/network/if-down directories.d, if-post-down.d, if-pre-up.d, if-up.d, then the corresponding directories for ppp interfaces are in /etc/ppp/ip-down.d, ip-up.d, etc. (for details on their purpose and function, see PPP HOWTO).
