ip nat inside source list VRF

Hi,

I have a Cisco 7204VXR with a NPE175 and 64 MG. I am using the IOS c7200-js-mz.122-32.bin. My problem is that I cannot form the VRF in "ip nat inside source list 2 interface loopback 2 vrf XXXXX overload". The commando vrf does not appear to me. An example:

interface Loopback2

ip vrf forwarding PRUEBA

ip address 10.10.10.10 255.255.255.255

Cisco7200(config)#ip nat inside source list 2 interface loopback 2 vrf PRUEBA overload

^

% Invalid input detected at '^' marker.

Cisco7200(config)#ip nat inside source list 2 interface loopback 2 ?

overload Overload an address translation

<cr>

So that I cannot form the VRF?

I must have another version of IOS?

Cheers

Hi,

You are right, your IOS doesn't support VRF Aware NAT, please use Cisco Feature Navigator to find the appropriate IOS:

Hi, Thanks for your aid.

The problem is that I only have 64 Mg and all the IOS require 128.

you know some IOS that has supported VRF Aware NAT and it only needs 64 Mg to work?

Cheers

Hi Eusebio,

Unfortunately you need at least 128M to support this feature on your platform.

HTH,

Mohammed Mahmoud.
