<br>
We are looking into way we can gradually deploy IPv6 in our
network…<br>
<br>
Already we have it running and we have one Test Machine……. The
challenge we are facing is that from that machine with IPv6 and
from other Machines with IPv4 we can’t communicate in either
direction..<br>
<br>
IPv6 Machine just communicate with IPv6 only machines like wise
IPv4 Machines just communicate with IPv4 machines ….<br>
<br>
A work around is to do NAT64 between the two subnets….<br>
<br>
It seems the hardware (Cisco 2921 router with IOS Version 15.0)
can’t do NAT64……..<br>
<br>
From the internet it seems NAT64 runs on IOS-XE and IOS-CGSE
which are Hardware dependent……..seems that we can’t upgrade IOS
Version 15.0 to any the two which supports NAT64.<br>
<br>
Before committing any expenses to acquire new router we want to
reach out to the community for comments and advises….<br>
<br>
Pls. review and advise.<br>

NAT64/DNS64 is supported on the ASR1000 without any additional
hardware.<br>
<br>
If you want to run it on the CRS or ASR9000, you will need the CGSE
line card.<br>
