IPv6 Devices Running Layer 3 Software
Before attaching equipment to a Foundry router, you must assign an interface IP address to the subnet on which
the router will be located. You must use the serial connection to assign the first IP address. For subsequent
addresses, you also can use the CLI through Telnet or the Web management interface.
By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You
can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-
interface table. See the
Foundry FastIron Configuration Guide
for more information.
The following procedure shows how to add an IPv6 address and mask to a router port.
1.
At the opening CLI prompt, enter
enable
.
FastIron>
enable
2.
Enter the following command at the CLI Privileged EXEC level prompt, then press
Enter
. This command
erases the factory test configuration if still present:
FastIron# erase startup-config
CAUTION:
Use the
erase startup-config
command only for new systems. If you enter this command on a
system you have already configured, the command erases the configuration. If you accidentally do erase the
configuration on a configured system, enter the
write memory
command to save the running configuration to
the startup-config file.
3.
Access the configuration level of the CLI by entering the following command:
Privileged EXEC Level:
FastIron
# configure terminal
Global CONFIG Level:
FastIron(config)
#
4.
Configure the IPv6 address and mask address for the interface:
FastIron(config)# int e 1/5
FastIron(config-if-e1000-1/5)# ipv6 address
2001:200:12D:1300:240:D0FF:FE48:4672:/64
These commands configure the global prefix 2001:200:12d:1300::/64 and the interface ID ::240:D0FF:FE48:4672,
and enable IPv6 on interface e 1/5.
NOTE:
The above procedure shows how to configure an IPv6 address with a manually configured Interface ID
as the address for the interface. You could also configure an IPv6 address with an automatically computed EUI-
64 Interface ID as the address for the interface. Link-local IPv6 addresses are also supported. For details, see
the
Foundry FastIron Configuration Guide
.
Syntax:
enable [<password>]
Syntax:
configure terminal
Syntax:
[no] ipv6 address <ipv6-prefix>/<prefix-length>
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons as documented
in RFC 2373.
You must specify the <prefix-length> parameter in decimal value. A slash mark (/) must follow the <ipv6-prefix>
parameter and precede the <prefix-length> parameter.
