The routers support Deterministic LSN44 and Deterministic DS-Lite. The basic deterministic NAT principle is applied equally to both NAT flavors. The difference between the two stem from the difference in interpretation of the subscriber – in LSN44 a subscriber is an IPv4 address, whereas in DS-Lite the subscriber is an IPv6 address or prefix (configuration dependent).
With the exception of classic-lsn-max-subscriber-limit and dslite-max-subscriber-limit commands in the inside routing context, the deterministic NAT configuration blocks are for the most part common to LSN44 and DS-Lite.
Deterministic DS-Lite section at the end of this section focuses on the features specific to DS-Lite.
