■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

1Create and delete WAN sub-interfaces The command is the same as above.

2Configure 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.
