The
ipv6 enable
command enables the tunnel. Alternatively, you could specify an IPv6 address, which
would also enable the tunnel.
Syntax:
ipv6 address
ipv6-prefix / prefix-length
[
eui-64
]
The
ipv6 address
command enables the tunnel. Alternatively, you could enter
ipv6 enable
, which
would also enable the tunnel.
Specify the
ipv6-prefix
parameter in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
Specify the
prefix-length
parameter as a decimal value. A slash mark (/) must follow the
ipv6-prefix
parameter and precede the
prefix-length
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.
For example, to clear statistics for tunnel 1, enter the following command at the Privileged EXEC level
or any of the Config levels of the CLI.
device#clear ipv6 tunnel 1
To clear statistics for all IPv6 tunnels, enter the following command.
device#clear ipv6 tunnel
Syntax:
clear ipv6 tunnel
[number]
The
number
parameter specifies the tunnel number.
Displaying IPv6 tunnel information
Use the commands in this section to display the configuration, status, and counters associated with
IPv6 tunnels.
Displaying a summary of tunnel information
To display a summary of tunnel information, enter the following command at any level of the CLI.
device#show ipv6 tunnel
