Default Configuration
IPv6 tunnel interfaces are not configured.
Command Mode
Interface (Tunnel) Configuration mode
User Guidelines
IPv6 tunneling consists of encapsulating IPv6 packets within IPv4 packets for
transmission across an IPv4 routing infrastructure.
The IPv6 interface is automatically enabled on a tunnel when it is configured
as an IPv6 tunnel by the tunnel mode ipv6ip command and the local IPv4 is
defined by the tunnel source command.
The IPv6 interface on an IPv6 tunnel is disabled if the tunnel stops to be an
IPv6 tunnel or the tunnel local IPv4 address is removed and the new IPv4
cannot be chosen.
ISATAP Tunnels
Using this command with the isatap keyword specifies an automatic ISATAP
tunnel. ISATAP tunnels enable transport of IPv6 packets within network
boundaries. ISATAP tunnels allow individual IPv4/IPv6 dual-stack hosts
within a site to connect to an IPv6 network using the IPv4 infrastructure.
ISATAP IPv6 addresses can use any initial Unicast /48 prefix. The final 64 bits
are an interface identifier. Of these, the leading 32 bits are the fixed pattern
0000:5EFE; the last 32 bits carry the tunnel endpoint IPv4 address.
Only the ipv6 address eui-64 command can be used to configured a global
unicast IPv6 on an ISATAP tunnel.
Example
Example 1—The following example configures an ISATAP tunnel:
console(config)# interface vlan 1
console(config-if)# ip address 1.1.1.1 255.255.255.0
console(config-if)# exit
console(config)# interface tunnel 1
console(config-if)# tunnel mode ipv6ip isatap
console(config-if)# tunnel source 1.1.1.1
