Chapter 4 - MultiFRAD Software
When you click the OK button in the IP WAN dialog box, you now have an IP address for a second logical WAN. Now we have to tie that IP address to a DLCI which in our example is DLCI 17. Now, return to the Frame Relay DLCI dialog box and highlight DLCI 17. Click the Protocol Mappings Map IP Address down arrow and the IP address 192.168.2.1 appears. Click this address and now IP address 192.168.2.1 is mapped to DLCI 17.
We now have WAN IP address 192.168.2.1 from the IP protocol stack mapped to DLCI 17. Let’s say we also want to map a data channel to DLCI 17. The data ports that are already mapped to other DLCIs are grayed out. In our example, lets map data port 3 to DLCI 17. Simply click Port 3 in the Data Port Mappings group and an X appears in the box at the left of Port 3. Now we have both data port 3 and IP WAN address 200.2.11.1 mapped to DLCI 17. The MultiFRAD enables multiple sources of data to be mapped to the same DLCI because the MultiFRAD multiplexes all the data onto the DLCI. In other words, bandwidth for that DLCI is shared by all the data sources mapped to the DLCI. Of course this means that all the data sources must go to the same remote site, since the frame relay network will send all data on DLCI 17 to the same place.
