how to configure a cisco 2960 switch to support two routers(data and voice), please give me any suggestions

[bezawada457]

HI, I need to configure a 2960 switch at a client site. They have routers already been installed on site, one is for data traffic another is for voice. I have created two vlans on switch  for data and voice. Now I couldn't get any idea what would be the default gateway on switch. 

Please give me any suggestions.

That is a trick question.

If your switch has only ONE uplink then you don't need a default-gateway.

HI Leo, 

            Many thanks for your reply.

         But there are two up-links going from Gi 0/1 and Gi 0/2. I have configured the S/W like below, 

interface GigabitEthernet0/1

description UPLINK TO Data router
switchport access vlan 100
 switchport mode access

!
interface GigabitEthernet0/2
description UPLINK TO voice router
switchport access vlan 100
 switchport mode access

interface Vlan1
 no ip address
 no ip route-cache
 shutdown
!
interface Vlan60
 ip address 192.168.1.253 255.255.255.0
 ip helper address 192.168.1.1
 no ip route-cache
!
interface Vlan100
 ip address 172.16.1.253 255.255.255.0
 ip helper address 172.16.1.1
 no ip route-cache

 I have used IP helper address, but I am getting some connecting issues on PCs and IP phones. Please suggest me, Can I manage it with two uplinks with different IP addresses. 

Thanks in advance.

Is the voice router and data router the same physical unit?  Why don't you just configure router-on-a-stick and enable dot1q trunking?  

You create a third VLAN.  The third VLAN is your management VLAN.  This is the VLAN you'll use to remotely connect to your routers and switches.

NO, those are two different routers and both are non-Cisco products. 

I haven't used trunking system here, I will try it now, 

Thanks for your advice.
