Configuration

assigned two subnets (they are not in the same VLAN), therefore, it is difficult to

management.

We can see that the number of the wasting IP address (such as subnet number,

broadcast address, default gateway address) is considerable and badly reduce the

addressing flexility that waste many addresses. Therefore, Super VLAN is developed for

solving the problem.

Super VLAN advantages are shown in the following:

Reduce IP address number about subnet number, default gateway address and broadcast

address

Implement that the different broadcast domains use addresses of the same subnet

segment

Enhance addressing flexility

Reduce the address waste

Figure 2-30 super vlan function

Super VLAN is different to the generic VLAN. Super VLAN only create a layer-3 interface

and does not include any ports, is a layer-3 notion.

Layer-3 interface of super VLAN is also at UP state as long as there is physical port is at

UP state in its sub-VLAN.
