Assigning IP Addresses by sppp Unit Number

If you are using either PAP or CHAP authentication, you can assign IP addresses to callers by the sppp unit number. The next table shows an example of this usage.

The plus (+) indicates that the unit number is added to the IP address. Addresses 10.10.111.240 through 10.10.111.255 are assigned to remote users. sppp0 gets IP address 10.10.111.240. sppp1 gets IP address 10.10.111.241, and so on.
