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-based or LLC-
based multiplexing in Menu 11.1.
VC-based Multiplexing
Remember that for VC-based multiplexing, 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.
IP Options:
Rem IP Addr: 0.0.0.0
Rem Subnet Mask= 0.0.0.0
My WAN Addr= 0.0.0.0
Single User Account= Yes
Metric= 2
Private= No
RIP Direction= None
Version= RIP-1
Multicast= None
IP Policies=
VPI #= 0
VCI #= 35
In this case, separate VPI and VCI numbers must be specified for each protocol.
LLC-based Multiplexing
For LLC-based multiplexing, one VC may carry multiple protocols with protocol identifying information
being contained in each packet header.
