5.1.1 Editing TCP/IP Options

Follow the steps below to edit Menu 11.3 – Remote Node Network Layer Options.

In Menu 11.1, move the cursor to the Edit IP/IPX/Bridge, then press [space bar] to toggle and set the value to Yes. Press [Enter] to open Menu 11.3 – Network Layer Options.

There are two versions of Menu 11.3 for the Prestige, depending on whether you chose VC-basedor LLC- based multiplexing in Menu 11.1.

VC-based Multiplexing

Remember that for VC-basedmultiplexing, by prior mutual agreement, a protocol is assigned a specific virtual circuit, e.g., VC1 will carry IP, VC2 will carry IPX, etc. However, note that for PPP or PPPoE encapsulation, we just need 1 VC no matter what protocol (IP/IPX/Bridge) is being carried.

IPX Options:

Rem LAN Net #= N/A

My WAN Net #= N/A

Hop Count= N/A

Tick Count= N/A

W/D Spoofing(min)= N/A

SAP/RIP Timeout(min)= N/A

Dial-On-Query= N/A

VPI #= N/A

VCI #= N/A

Bridge Options: Dial-On-Broadcast= N/A Ethernet Addr Timeout(min)= N/A VPI #= N/A

VCI #= N/A

Enter here to CONFIRM or ESC to CANCEL:

Separate VPI and VCI numbers must be specified for each protocol when using VC-based multiplexing as there must be a distinct PVC for each

Figure 5-2 Menu 11.3 for VC-based Multiplexing

In this case, separate VPI and VCI numbers must be specified for each protocol.

LLC-based Multiplexing

For LLC-basedmultiplexing, one VC may carry multiple protocols with protocol identifying information being contained in each packet header.
