I have to configure static NAT (1IP to 1 IP NAT44) in default vrf. I don't want to buy ISM/VSM and licence CGv6
The traffic will be very low (maximum 10000 session per second). I don't want to place a new router. ARS9k has 4.2.1 frimware version.
Can I run static NAT44 in default VRF without ISM or VSM module?
unfortunately no, even at very low speed, we can not perform NAT tasks on ASR9000 without a service card.
