IPv6 Addressing and Basic Connectivity” chapter of Cisco IOS IPv6 Configuration Library on Cisco.com. IPv6 Applications The switch has IPv6 support for these applications: Ping, traceroute, Telnet, TFTP, and FTP Secure Shell (SSH) over an IPv6 transport HTTP server access over IPv6 transport DNS resolver for AAAA over IPv4 transport Cisco Discovery Protocol (CDP) support for IPv6 addresses For more information about managing these applications, see the “Managing Cisco IOS Applications over IPv6” chapter and the “Implementing IPv6 Addressing and Basic Connectivity” chapter in the Cisco IOS IPv6 Configuration Library on Cisco.com. Dual IPv4 and IPv6 Protocol Stacks You must use the dual IPv4 and IPv6 template to allocate ternary content addressable memory (TCAM) usage to both IPv4 and IPv6 protocols. Dual IPv4 and IPv6 Support on an Interface shows a router forwarding both IPv4 and IPv6 traffic through the same interface, based on the IP packet and destination addresses. Figure 42-1 Dual IPv4 and IPv6 Support on an Interface Use the dual IPv4 and IPv6 switch database management (SDM) template to enable dual-stack environments (supporting both IPv4 and IPv6). For more information about the dual IPv4 and IPv6 SDM template, see Chapter11, “Configuring SDM Templates” The dual IPv4 and IPv6 templates allow the switch to be used in dual-stack environments. If you try to configure IPv6 without first selecting a dual IPv4 and IPv6 template, a warning message appears. In IPv4-only environments, the switch applies IPv4 QoS and ACLs in hardware. IPv6 packets are not supported. In dual IPv4 and IPv6 environments, the switch applies IPv4 QoS and ACLs in hardware. IPv6 QoS and ACLs are not supported. If you do not plan to use IPv6, do not use the dual-stack template because this template results in less TCAM capacity for each resource. For more information about IPv4 and

IPv4 to IPv6 Converter - IPv4-Mapped IPv6

To the SP’s IPv4 address before routing the packet to the public IPv4 network. The exact reverse is performed for traffic coming from the public IPv4 network to the subscriber. Figure 1. MAP-T Network By using MAP-T, you can transition the SP network to an IPv6-only architecture while allowed subscribers to continue using IPv4 and communicate with IPv4-only Internet or other sites outside the SP network. MAP-T behaves like a NAT64 translation but instead of using an IPv6 address with an embedded IPv4 address, it uses an encoding scheme that also embeds the port number. Thus, MAP-T provides a way to restrict the port range used by devices. A MAP-T system includes the following: Customer Edge (CE) device—The CE is a home gateway (wireless router, cable modem with router, and so forth). The CE provides IPv4/IPv6 translation as well as native IPv6 forwarding. It has one WAN-side provider-facing IPv6-addressed interface and one or more LAN-side interfaces addressed using private IPv4 addressing. You would configure one or more MAP domains for the CE to use to translate IPv4 packets to IPv6 and vice-verse. Border Relay (BR) device—You would install the ASA as a border relay. The BR is a provider-side component at the edge of the MAP domain that supports the IPv4/IPv6 translation. The BR has at least one IPv6-enabled interface and one IPv4 interface connected to the IPv4 network. You would configure one or more MAP domains for the BR to use to translate IPv4 packets to IPv6 and vice-verse.. The IPv4 to IPv6 tool convert the given IPv4 address into a IPv6 address notation.

These leave the packet unchanged and are discarded when we enqueue the packet for forwarding to the next hop. Imposition MarkingUnder special circumstances, you can mark a header field that has not yet been added to a packet (we term this behavior imposition marking). The most common example of imposition marking is the application ofthe set mpls experimental imposition command - you can use it on an ingress interface where a packet may arrive containing an IP datagram and no multiprotocol label switching (MPLS) header. When and if the router encapsulates the datagram with a MPLS header, the EXP bits will be marked accordingly as specified by this command.Application of the set dscp tunnel and set precedence tunnel commands (for IPv4 only) represent another example of imposition marking. If an egress policy is applied on a tunnel interface, no tunnel header exists when the policy executes. This means that any marking would apply to the original (eventually inner) IP header. Using either command, you can mark the tunnel (outer) IP header and leave the original header unchanged. The following table lists the tunnel types and encapsulation variants that support these commands: Table 1 Supported DSCP and Precedence Tunnel Marking Configurations Name Outer Header (encapsulating) Inner Header (payload) Comments GRE (4 over 4) IPv4/GRE IPv4 Supported GRE (6 over 4) IPv4/GRE IPv6 Encapsulation not supported GREv6 (4 over 6) IPv6/GRE IPv4 Encapsulation not supported GREv6 (6 over 6) IPv6/GRE IPv6 Encapsulation not supported IP-IP IPv4 IPv4 Supported IPv6-IP IPv4 IPv6 Supported IPv6 (4 over 6) IPv6 IPv4 Encapsulation not supported IPv6 (6 over 6) IPv6 IPv6 Not supported IPSEC (4 over 4) IPv4/IPSEC IPv4 Not supported IPSEC (6 over 4) IPv4/IPSEC IPv6 Not supported IPSECv6 (4 over 6) IPv6/IPSEC IPv4 Encapsulation not supported IPSECv6 (6 over 6) IPv6/IPSEC IPv6 Not supported

Addresses to each connected device), unlike IPv4 addresses however, IPv6 addresses are 128-bit numerical numbers, using hexadecimal notation. Because of this wider scale of available unique numbers, they can assign a significantly larger number of devices at any one time. How many IPv6 addresses are there? Because of the much larger scale of IPv6, it allows for a significantly larger amount of unique IP addresses. Approximately that accommodates around 340 undecillion unique IP addresses (which when written down is; 340,282,366,920,938,463,463,374,607,431,768,211,456). That's an insanely big number and we'll never run out of addresses again. What is the difference between an IPv4 and IPv6 address? The main difference between IPv4 and IPv6 addresses is the address length. IPv4 addresses are 32 bits in length, while IPv6 addresses are 128 bits long. IPv4 addresses use decimal notation while IPv6 addresses use hexadecimal. IPv4 is separated by dots whereas IPv6 is separated by colons. IPv4 includes a checksum field in its header whereas IPv6 doesn't. This change was made to IPv6 to reduce processing overhead and improve efficiency..
