Networking Diagram; Configuration Procedure - 3Com 3032 Configuration Manual

IPX network number which is different from that of the affiliated WAN
interface, and other IPX working parameters
Virtual circuit of the sub-interface
Please see chapters in Operation Manual - Link Layer Protocol and Operation
Manual - Network Protocol for details about the above configurations.
Configure sub-interfaces of WAN interface which link layer protocol is X.25
1 Create and delete WAN sub-interfaces
The command is the same as above.
2 Configure relevant working parameters
The following items can be configured on the sub-interface of WAN interface
which link layer protocol is X.25:
X.25 address mapping different from the affiliated WAN interface (i.e. the main
interface)
IP address which is not in the same network segment as the affiliated WAN
interface
IPX network number which is different from that of the affiliated WAN
interface, and other IPX working parameters
Virtual circuit of the sub-interface
Please see chapters in the Operation Manual - Link Layer Protocol and Operation
Manual - Network Protocol for details about the above configurations, and
sub-interface monitoring and maintenance. No further details are provided here.
Typical WAN sub-interface configuration example
I. Networking Requirements
As shown below, WAN interface Serial0 of router A is connected with router B and
router C via public frame relay network. By configuring sub-interfaces on Serial0
of router A, LAN 1 can simultaneously access LAN 2 and LAN 3 via Serial0.
