■
X.25 address mapping different from that of the WAN interface (also known as
the primary interface)
■
IP addresses in a network segment different from the network segment that
the WAN interface resides
■
IPX network numbers and IPX operation parameters different from those of the
WAN interface
■
Virtual circuits corresponding to a sub-interface
For the detailed configuration information, refer to “X.25 and LAPB
Configuration” on page 283 and “IPX Configuration” on page 2217 .

Configure relevant operation parameters
On ATM sub-interfaces, you can configure:
■
IP addresses in a network segment different from the network segment that
the WAN interface resides
■
Virtual circuits corresponding to a sub-interface
For the detailed configuration information, refer to “ATM and DSL Interface
Configuration” on page 71 .
Ethernet Sub-interface
Configuration Example
Network requirements
As shown in Figure 148 , the encapsulation type for the VLAN ports of Switch 1
and Switch 2 is dot1q, workstation A and C belong to VLAN 10, and workstation
B and D belong to VLAN 20. It is required that:
■
The IP addresses of router subinterfaces Ethernet 3/0.10, Ethernet 3/0.20,
Ethernet 4/0.10, and Ethernet 4/0.20 are 1.0.0.1/8, 2.0.0.1/8, 3.0.0.1/8, and
4.0.0.1/8.
■
Work station A can intercommunicate with work station B, and work station C
can intercommunicate with work station D, that is, devices connected to the
same switch but belonging to different VLANs can intercommunicate with each
other.
■
Work station A can intercommunicate with work station C, and work station B
can intercommunicate with work station D, that is, devices connected to

Required
If the specified ATM sub-interface does not
exist, this command first creates the
sub-interface and then enters the
sub-interface view.
By default, point-to-multipoint
sub-interfaces are created.
