ISATAP tunnel interface IPv6 addresses embed the IPv4 address in the last

two quartets.

ISATAP tunnels do not use a special reserved range of IPv6 addresses at all,

instead using just normal IPv6 unicast prefixes.

ISATAP tunnels typically use a single prefix to which all tunnel interfaces

connect, so all routers have a connected IPv6 route to that same subnet.

ISATAP tunnels can automatically derive the tunnel interfaces interface ID

by using modified EUI-64 rules.

The router adds 0000:5EFE as quartets 5 and 6.

The router finds the tunnels source IPv4 address, converts it to hex, and

adds that as quartets 7 and 8.

Router(config)# ipv6 unicast-routing

If using a new loopback interface, create the loopback

Router(config)# interface loopback

Router(config)# interface tunnel

Router(config-if)# tunnel source

Do NOT define a tunnel destination.

Router(config-if)# tunnel mode ipv6ip isatap

Router(config-if)# ipv6 address eui-64
