Hi Suresh,

The process of configuring multiple subnets per VLAN (or Ethernet segment) is called multinetting. One way to do this is to configure 2 IP addresses on your routed Ethernet interface (either 'interface vlan or interface FastEthernet etc) and then assign addresses out of the 2 ranges to your workstation.

Hope that helps.

Hi Suresh,

Using a secondary keyword after ip address under interface vlan mode you can achieve the desired results.

interface vlan 1

ip address 1.1.1.1 255.255.255.0

ip address 2.2.2.2 255.255.255.0 secondary

ip address x.x.x.x x.x.x.x secondary

Now you can have you machines in same vlan with different subnets.

It is recommended by Cisco. As Cisco itself says that you should not configure more than 254 clients per vlan. Right.
