The following case study configures PAT on the RAS 1500, with 2 channel
multilink PPP connected to the ISP with dial-on-demand and
bandwidth-on-demand. The 2 channels may be either ISDN or analog
interfaces and assume that you have already configured the ISDN
modems for proper operation. However, adding more than 4 Multi-Link
Point-to-Point Protocol (MLPPP) links diminishes the gain of adding the
channels because of the MLPPP overhead.
