Brief Summary

The Mapping of Address and Port (MAP) technology provides a high-performance solution to carrying IPv4 traffic over an IPv6-only network. MAP comprises two variants: MAP-E (Encapsulation mode) transports IPv4 packets by encapsulating the IPv4 packet inside an IPv6 packet. MAP-T (Translation mode) transports IPv4 packets by encoding their IPv4 addresses inside the IPv6 addresses and carries the IPv4 payload directly.

Дурной вопрос - а что, mpls на этих ipv6-only сетях им. Cisco не работает ? Overhead чуть-ли не на порядок меньше... -- In theory, there is no difference between theory and practice. But, in practice, there is.
