ifconfig Section for Multipoint Dial-in Server

The ifconfig section for a multipoint dial-in server has a slightly different syntax than that for a point-to-point link. This syntax is:

ifconfig ipdn plumb server-name up

The major difference is that no destination end points are listed as arguments to ifconfig. Instead, the link manager picks up this information from the path section of the asppp.cf file.

In Example 9-2, the link manager first runs the ifconfig command on the dial-in server to configure multipoint interface ipd0. The zero in ipd0 gives the device number of the interface. The option plumb performs various activities necessary for IP to recognize the ipd0 interface. The ifconfig option up marks interface ipd0 as up.

You may have to supply a netmask + parameter on the ifconfig line if you use subnetting.
