Hi Asheesh, we have some good ISM/CGN support forum documents available too. Not sure if they specifically list a nat64 config, so in the potential absence of that here you go:
•Configure CGN role, INFRA SVI as below.
For CGN role, serviceInfra should have a address mask of at least /30
conf t
int serviceInfra1
ipv4 add 1.1.1.1/30
service-location 0/2/cpu0
commit
exit
hw-module service cgn location 0/2/cpu0
commit
exit
NAT64 Configuration – V4 ServiceApp and Static Route
conf t
int serviceApp41
service cgn cgn1 service-type nat64 Stateful
ipv4 add 41.41.41.1/30
commit
exit
router static
address-family ipv4 unicast
52.52.52.0/24 ServiceApp41 41.1.1.2
commit
exit
end
