ZyXEL Communications 641 manual VC-Based Multiplexing, LLC-based multiplexing

Prestige 641 ADSL Internet Access Router

There are two versions of menu 11.3 for the P641, 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.

Menu 11.3 - Remote Node Network Layer Options

IP Options:	IPX Options :
IP Address Assignment= Static	Rem LAN Net #= 00000000
Rem IP Addr: 0.0.0.0	My WAN Net #= 00000000
Rem Subnet Mask= 0.0.0.0	Hop Count= 1
My WAN Addr= 0.0.0.0	Tick Count= 2
Single User Account= Yes	VPI #= 1
Metric= 2	VCI #= 2
Private= No
RIP Direction= Both	Bridge Options:
Version= RIP-2B	Ethernet Addr
VPI #=1	Timeout(min)= 0
VCI #=1	VPI #= 1
	VCI #= 3

Separate VPI and VCI numbers must be specified for each protocol.

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 carries multiple protocols with protocol identifying information being contained in each packet header.

Menu 11.3 - Remote Node Network Layer Options

VPI/VCI (RFC1483 LLC/PPP/ENET ENCAP) :	IPX Options :
VPI #= 1	Rem LAN Net #= 00000000
VCI #= 1	My WAN Net #= 00000000
IP Options :	Hop Count= 1
IP Address Assignment= Static	Tick Count= 2
Rem IP Addr: 0.0.0.0
Rem Subnet Mask= 0.0.0.0	Bridge Options:
My WAN Addr= 0.0.0.0	Ethernet Addr Timeout(min)= 0
Single User Account= No
Metric= 2
Private= No
RIP Direction= Both
Version= RIP-2B

Only one set of VPI and VCI numbers need be specified.

Figure 5-3 Menu 11.3 for LLC-based multiplexing

In this case, only one set of VPI and VCI numbers need be specified for all protocols.
