Multiple IPs of VLAN

[Dinesh Kumar Mariappan]

                    can we assigned Multiple IPs on Single VLAN. by using the IP address X.X.X.X X.X.X.X secondary

My query is

VLan 10

I had different IP for different user on VLAN 10

10.10.10.1/24 for 1st floor

10.10.20.1/24 for 2nd floor

10.10.30.1/24 for 3rd floor

simliarly up to 10 floor.

can all these IP will communicate with same VLAN 10..  only  Primary IP assigned in VLAN 10 P will work r and est of other user cant able to communicate? or all the users will able to communicate with out disturbance..

Yes you can. It works fine. You'd need to add your other subnets as a secondary address, but it would look something like this:

int vlan 10

ip address 10.10.10.1 255.255.255.0

ip address 10.10.20.1 255.255.255.0 secondary

ip address 10.10.30.1 255.255.255.0 secondary

HTH,
John

It is a bit of a weird way of doing things though. More standard way to do things is to have a separate VLAN for each floor, trunked interfaces down to each floor switch and L3 SVI for each VLAN configured on the switch.

I agree with John. It works fine.

U can have many subnets as u want.
