assign 2 ip address of same network on same router interface for configuring vlan

[teslykuriakose]

hi, 

I wanted to assign 2 ip address of same network on same router interface.

i am able to assign 2 ip address of different network in same router interface. But i want to try it with same network

it is not possible until you subnet them into 2 networks?

why do you need 2 IP address the same range? if they going to the same network segment?

Thanks for answer. actually i did like that because that two ip address is going to different vlans.

I thought that in order to assign vlan we don't need to subnet..

when i searched on internet i found that we dont need to subnet an ip address for creating vlans. thats why i asked

the only option as per requirement is a secondary IP address.

ip address 192.168.3.1 255.255.255.0 

ip address 192.168.3.2 255.255.255.0 secondary

Hi there,

Have you tried using the secondary command?

!
int vlan 10
  ip address 192.168.1.1 255.255.255.0
  ip address 192.168.1.2 255.255.255.0 secondary
!

....or configure a FHRP like HSRP with just one active router:

!
int vlan 10
  ip address 192.168.0.1 255.255.255.0
  standby 1 ip 192.168.0.2
!

cheers,

Seb.
