IPv6 over IPv4 tunnels

Brocade(config)#interface tunnel 1
Brocade(config-tnif-1)#tunnel source ethernet 1/1/1
Brocade(config-tnif-1)#tunnel destination 192.162.100.1
Brocade(config-tnif-1)#tunnel mode ipv6ip
Brocade(config-tnif-1)#ipv6 enable
This example creates tunnel interface 1 and assigns a link local IPv6 address with an automatically
computed EUI-64 interface ID to it. The IPv4 address assigned to Ethernet interface 1/1/1 is used
as the tunnel source, while the IPv4 address 192.168.100.1 is configured as the tunnel
destination. The tunnel mode is specified as a manual IPv6 tunnel. Finally, the tunnel is enabled.
Note that instead of entering ipv6 enable, you could specify an IPv6 address, for example, ipv6
address 2001:DB8:384d:34::/64 eui-64, which would also enable the tunnel.
Syntax: [no] interface tunnel
For the parameter, specify a value between 1 – 8.
Syntax: [no] tunnel source | ethernet // | loopback
| ve
The tunnel source can be an IP address or an interface.
For , use 8-bit values in dotted decimal notation.
The ethernet | loopback | ve parameter specifies an interface as the tunnel source.Specify the
ethernet port in the // format. Stack-unit is 1.
If you specify a loopback, VE, or interface, also specify the loopback, VE, or number, respectively.
Syntax: [no] tunnel destination
Specify the parameter using 8-bit values in dotted decimal notation.
Syntax: [no] tunnel mode ipv6ip
ipv6ip indicates that this is an IPv6 manual tunnel.
Syntax: ipv6 enable
The ipv6 enable command enables the tunnel. Alternatively, you could specify an IPv6 address,
which would also enable the tunnel.
Syntax: ipv6 address / [eui-64]
The ipv6 address command enables the tunnel. Alternatively, you could enter ipv6 enable, which
would also enable the tunnel.
Specify the parameter in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
Specify the parameter as a decimal value. A slash mark (/) must follow the
parameter and precede the parameter. The eui-64 keyword
configures the global address with an EUI-64 interface ID in the low-order 64 bits. The interface ID
is automatically constructed in IEEE EUI-64 format using the interface’s MAC address.
Clearing IPv6 tunnel statistics
You can clear statistics (reset all fields to zero) for all IPv6 tunnels or for a specific tunnel interface.
