16 At the beginning: Global v4 only service Internet (v4 only) EBGP Router Nationwide / International Back bone (v4 only) Access Concentrator One Global IPv4 address ADSL,FTTH,etc. LAN CPE Router /w NAT End Host RFC1918 Based Private address (typically /24) Dual Stack backbone (it s easy) Internet (v4/v6) EBGP Router Nationwide / International Back bone (v4/v6) Access Concentrator (v4) One Global IPv4 address ADSL,FTTH,etc. LAN CPE Router (v4) /w NAT RFC1918 Based Private address (typically /24) End Host
17 Introducing CGN Internet (v4/v6) EBGP Router Nationwide / International Back bone (v4/v6) Carrier Grade NAT ADSL,FTTH,etc. Access Concentrator (v4) One Private IPv4 address From New Private space LAN CPE Router (v4) RFC1918 Based Private address (typically /24) End Host Introducing Softwire (v6 over v4 L2TP) Internet (v4/v6) EBGP Router Nationwide / International Back bone (v4/v6) ADSL,FTTH,etc. Carrier Grade NAT Access Concentrator (v4) SOFTWIRE Concentrator One (new) Private IPv4 address LAN If softwire client has v6 routing function, delegated IPv6 is here CPE Router (v4 NAT) End Host (v4/v6) RFC1918 Based Private address (typically /24) SOFTWIRE Client (v6 over v4 L2TP)
