Sun Microsystems 3U manual Classical IP Interface Type

If you are planning to run NIS over your ATM network, you must specify the list of NIS servers (ypservers) using the ypinit -ccommand. See the ypinit(1M) man page for details of setting up the ypserver. Be sure that the IP addresses of the ypservers are listed in the /etc/hosts file.

The Routing Information Protocol (RIP) also uses the broadcast feature of IP, so it is not supported under the Classical IP environment. In the Solaris operating environment, RIP is implemented by the daemon in.routed.

Classical IP alone also does not support the multicast packet delivery system. If you are using Classical IP, you must explicitly add the routes to the routers in the ATM subnet. You may also specify one router as the default router to provide connectivity outside of the ATM subnet. See the route(1M) man page for information on using the route command to add specific router entries and to add a default router.

You can use the Classical IP parameter group menu to define the Classical IP configuration of a SunATM interface.

Classical IP Interface Type

The SunATM software allows you to configure your interface as either a Classical IP ARP server or a client. In addition, you can connect two systems back-to-back, in a standalone configuration, using a Permanent Virtual Circuit (PVC). These three modes are options on the Classical IP parameter menu.
