IPv6 - 6to4 Tunnels using IPv4 EIGRP routes

In this lab, configure all routers with IPV6 and IPV4 addresses and establish communication between R1 and R3 using IPv6to4 tunnelling.

Objectives are as follows;

(1) Configure EIGRP for IPV4.

(2) Create a 6to4 tunneling

(3) Configure static IPv6 routes.

To download the completed GNS3 files, get from https://docs.google.com/leaf?id=0B889ogd4ltI2NDU1OTcxOTgtZjgwYS00Y2Q5LWFiZTMtNThjYTk0NTBmMTg0&hl=en&authkey=CPGAn8IE

In R1, configure the following configurations for tunnelling.

interface Tunnel0

 no ip address

 no ip redirects

 ipv6 address 2002:AC10:C01:1::1/64

 tunnel source Serial0/0

 tunnel mode ipv6ip 6to4

For IPv6 routing,

ipv6 unicast-routing

ipv6 route 2002::/16 Tunnel0

ipv6 route FEC0::3:0/112 2002:AC10:1703:1::3

Enabling simple EIGRP routing for IPv4 networks are as follow;

router eigrp 1

 network 10.0.0.0

 network 172.16.0.0

 no auto-summary

Result of routing in R1 are as follow;
