Mapping of Address and Port with Encapsulation (MAP-E) Softwires for CGNAT Next Gen Services

Mapping of Address and Port with Encapsulation (MAP-E) softwires are supported for CGNAT Next Gen Services. MAP-E is an automatic tunneling mechanism tailored for deployment of IPv4 to end users via a service provider's IPv6 network infrastructure. Using MAP-E technology, islands of v4 networks can be connected via v6 tunnels. The IPV4 packets are carried in IPV4-over-IPV6 tunnels from the MAP-E Customer Edge (CE) routers to the MAP-E Border Relay(s) (BR) (through IPV6 routing topology), where they are de-tunneled for further processing. MAP-E can be used by Service Providers to provide IPv4 connectivity to their subscribers over the ISP's IPv6 access network.
