ides a way to utilize an existing IPv o datagra Tunneli e end-to- re determining the p Tunneling Tunneling is a method and generic mechanism by which a packet is encapsulated and carried as payload within an IPv6 packet. The resulting packet is called an IPv6 tunnel packet. The forwarding path between the source and destination of the tunnel packet is called an IPv6 tunnel. The technique is called IPv6 tunneling. This would establish a "virtual link" between two IPv6 nodes for transmitting data packets as payloads of IPv6 packets. From the point of view of the two nodes, this "virtual link," called an IPv6 tunnel, appears as a point-to-point link on which IPv6 acts like a link-layer protocol. The two IPv6 nodes play specific roles. One node encapsulates original packets received from other nodes or from itself and forwards the resulting tunnel packets through the tunnel. The other node decapsulates the received tunnel packets and forwa re called the tunnel entry-point node, and it is the source of the tunnel packets. The decapsulator node is called the tunnel exit-point, and it is the destination of the tunnel packets. The encapsulation takes place in an IPv6 tunnel entry-point node, as the result of an original packet being forwarded onto the virtual link represented by the tunnel. The original packet is processed during forwarding according to the in Upon receiving an IPv6 packet destined to an IPv6 address of a tunnel exit-point node, its IPv6 protocol layer processes the tunnel headers. The key to a successful IPv6 transition is compatibility with the large installed base of IPv4 hosts and routers. Maintaining compatibility with IPv4, while deploying IPv6, will streamline the task of transitioning the Internet to IPv6. The mechanisms are designed to be employed by IPv6 hosts and routers that need to interoperate with IPv4 hosts and utilize IPv4 routing infrastructures. We expect that most nodes in the Internet will need such compatibility for a long time to come, and perhaps even indefinitely. Because they support both c DHCP) to acquire their IPv4 addresses, and IPv6 protocol mechanisms (e.g., stateless address autoconfiguration) to acquire their IPv6-native addresses. In most deployment scenarios, the IPv6 routing infrastructure will be built up over time. While the IPv6 infrastructure is being deployed, the existing IPv4 routing infrastructure can remain functional and can be used to carry IPv6 tr 4 r uting infrastructure to carry IPv6 traffic. IPv6/IPv4 hosts and routers can tunnel IPv6 ms over regions of IPv4 routing topology by encapsulating them within IPv4 packets. ng can be used in a variety of ways: • Router-to-Router. IPv6/IPv4 routers interconnected by an IPv4 infrastructure can tunnel IPv6 packets between themselves. In this case, the tunnel spans one segment of the end-to-end path that the IPv6 packet takes. • Host-to-Router. IPv6/IPv4 hosts can tunnel IPv6 packets to an intermediary IPv6/IPv4 router that is reachable via an IPv4 infrastructure. This type of tunnel spans the first segment of the packet’s end-to-end path. • Host-to-Host. IPv6/IPv4 hosts that are interconnected by an IPv4 infrastructure can tunnel IPv6 packets between themselves. In this case, the tunnel spans the entir end path that the packet takes. • Router-to-Host. IPv6/IPv4 routers can tunnel IPv6 packets to their final destination IPv6/IPv4 host. This tunnel spans only the last segment of the end-to-end path. Copyright IPexpert, Inc. ( 2005. All Rights Reserved. 15 IPexpert’s IPv6 eBook In the first two tunneling methods listed above – router-to-router and host-to-router – the IPv6 packet is being tunneled to a router. The endpoint of this type of tunnel is an intermediary router, which must decapsulate the IPv6 packet and forward it on to its final destination. When tunneling to a router, the endpoint of the tunnel is different from the destination of the packet being nneled. So the addresses in the IPv6 packet being tunneled can not provide the IPv4 address node to etermine tunnel endpoint IPv4 address automatically. Automatic tunneling employs this aque to users of the network, and is not detectable by network iagnostic tools such as traceroute. The single-hop model is implemented by having the sulating the packet, the IPv6 header is not modified. As part of the decapsulation the ULD silently discard a packet with an invalid IPv4 source address such as a multicast cast address, 0.0.0.0, and 127.0.0.1. permanent solution. ith other such IPv6 domains or osts with minimal manual configuration.

Only a modest amount of router onfiguration is required. tu of the tunnel endpoint. Instead, the tunnel endpoint address must be determined from configuration information on the node performing the tunneling. We use the term "configured tunneling" to describe the type of tunneling where the endpoint is explicitly configured. In the last two tunneling methods – host-to-host and router-to-host – the IPv6 packet is tunneled all the way to its final destination. In this case, the destination address of both the IPv6 packet and the encapsulating IPv4 header identify the same node! This fact can be exploited by encoding information in the IPv6 destination address that will allow the encapsulating d technique, using a special IPv6 address format with an embedded IPv4 address to allow tunneling nodes to derive automatically the tunnel endpoint IPv4 address. This eliminates the need to explicitly configure the tunnel endpoint address, greatly simplifying configuration. IPv6-over-IPv4 tunnels are modeled as "single-hop." That is, the IPv6 hop limit is decremented by 1 when an IPv6 packet traverses the tunnel. The single-hop model serves to hide the existence of a tunnel. The tunnel is op d encapsulating and decapsulating nodes process the IPv6 hop limit field as they would if they were forwarding a packet on to any other datalink. That is, they decrement the hop limit by 1 when forwarding an IPv6 packet. When decap node SHO address, a broad IP6to4 Effectively, it treats the wide area IPv4 network as a unicast point-to-point link layer. The mechanism is intended as a start-up transition tool used during the period of co-existence of IPv4 and IPv6. It is not intended as a This is considered to be an interim solution and requires that sites should migrate when possible to native IPv6 prefixes and native IPv6 connectivity. This will be possible as soon as the site’s ISP offers native IPv6 connectivity. The motivation for this method is to allow isolated IPv6 sites or hosts, attached to a wide area network which has no native IPv6 support, to communicate w h require IPv4- compatible IPv6 addresses or configured tunnels. In this way, IPv6 gains considerable independence of the underlying wide area network and can step over many hops of IPv4 subnets.

Using an EUI-64 interface ID, configure Loopback address on R2, R4, R5, R6, as indicated in table above. B. R2's s0/1/0, R5's s0/1/0 and R6's s4/0 are the main FR cloud. Configure multipoint sub-interface on R2's s0/1/0 and use physical interfaces for R5 and R6. C. Configure a point-to-point sub-interface for the FR connection between R2's s0/1/0 and R4's s0/0/0. D. Configure a host table on every router with the IPv6 address. E. Configure a static route for R4 pointing to R5’s loopback. Change the administrative distance to 2. F. Configure OSPF Area 0 for R2's loopback, s0/1/0.256, R5's loopback, s0/1/0, R6's loopback and s4/0. Use x.x.x.x as the router-ID, where x is the router number. For example, R2 should have router-ID as 2.2.2.2. G. Configure OSPF Area 24 for R2's s0/1/0.24, R4's s0/0/0.24 and loopback 0. H. Configure RIP for R2's s0/1/0.24, R4's s0/0/0.24 and loopback 1. I. Redistribute OSPF and RIP into each other. The RIP metric after redistribution should be 7 and the OSPF Type 1 metric should be 1000. J. Verify connectivity by telnetting and pinging different places. IPv6 Lab Instructor’s Comments and Technical Tips A. To configure an IPv6 address for an interface and enable IPv6 processing on the interface using an EUI-64 interface ID in the low order 64 bits of the address, use the IPv6 address EUI-64 command. B. The Frame Relay map IPv6 command is similar to the Frame Relay map command, except that it is IPv6-specific. The Frame Relay map defines the logical connection between a specific protocol and address pair and the correct DLCI. C. None. Copyright IPexpert, Inc. ( 2005. All Rights Reserved. 20 IPexpert’s IPv6 eBook D. To define a static host name-to-address mapping in the host name cache, use the IPv6 host command. E. Use the IPv6 route command to implement static multicast routes in IPv6. The administrative-multicast-distance argument determines the distance that will be used. F. You can configure an arbitrary value in the IP address format for each router. However, each router ID must be unique. The router ID is chosen automatically from among the set of IPv4 addresses configured on the router. G. None. H. In IPv4, the network-number router configuration command is used to implicitly specify the interfaces on which to run IPv4 RIP. The IPv6 rip enable command is used to enable IPv6 RIP explicitly on required interfaces. Use the IPv6 router rip command to enable an IPv6 RIP routing process. Configuring this command places the router in router configuration mode for the IPv6 RIP routing process. I. None. J. None.
