Sub-Interface 159
■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.
