What are two limitations when in use of NPTv6 for IPV6 vs IPV6 Address translation?
A. stateful address translation
B. a limit of 32 1-to-1 translations
C. lack of overloading functionality
D. identify all interfaces NAT inside or outside
E. 1-to-1 prefix rewrite
F. mismatched prefix allocations

The IPv6-to-IPv6 Network Prefix Translation (NPTv6) provides a mechanism to translate an inside IPv6 source address prefix to outside IPv6 source address prefix in IPv6 packet header and vice-versa.
The ASR1K NPTv6 does not create any state in the date plane and hence can operate using minimal memory and also supports high availability by default.
