Hi Rahul,

DS-Lite is only supported on the CGSE in CRS and on the ISM in the ASR9k. Here is a sample config that might help you to understand.

RP/0/RSP0/CPU0:router(config)#

interface te0/0/0/0

ipv6 add 2001:db8:ff00::1/64

!

interface te0/1/0/0

ipv4 add 192.168.100.1/24

!

interface ServiceApp61

ipv6 address 2001:db8:1::1/64

service cgn demo service-type ds-lite

!

interface ServiceApp41

ipv4 address 192.168.1.1 255.255.255.252

service cgn demo service-type ds-lite

!

service cgn demo

service-type ds-lite dslite-1

map address-pool x.y.z.0/24

aftr-tunnel-endpoint-address 2001:db8:ffff::1

   interface ServiceApp42
