Configuring IPv6 IS-IS
The area-id parameter specifies the area and has the format xx or xx.xxxx. For example, 49 and
49.2211 are valid area IDs.
The system-id parameter specifies the device’s unique IS-IS router ID and has the format
xxxx.xxxx.xxxx. You can specify any value for the system ID. A common practice is to use the
device’s base MAC address as the system ID. The base MAC address is also the MAC address
of port 1. To determine the base MAC address, enter the following command at any level of the
CLI: show interfaces brief. The base MAC address is listed in the first row of information, in the
MAC column.
You must use the same system ID in all the NETs on the device.
NOTE
The parameter descriptions above are the recommended values for the NET. However, the CLI
accepts any value that fits within the following lengths and formats:
xx.xxxx.xxxx.xxxx.00 – minimum length of NET
xx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.xxxx.00 – maximum length of NET
The sel parameter specifies the NSAP Selector (SEL). This value must always be 00 (two zeros).
The value 00 indicates that this address is an NET.
To delete a NET, use the no form of this command.
4. Configure an IPv6 IS-IS single topology. Refer to
“Configuring IPv6 IS-IS single topology”
5. Configure IS-IS parameters. Refer to the sections
“Globally configuring IS-IS on a device”
“Configuring IPv6 specific address family route parameters”
on page 715, and
“Configuring IS-IS properties on an interface”
Enabling IS-IS and assigning an IPv6 address to an interface
To configure IPv6 IS-IS on the desired device interfaces, enter commands such as the following:
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# ipv6 address 2001:db8:12d:1300::/64 eui-64
Brocade(config-if-e100-3/1)# ipv6 router isis
The commands in this example assign the global IPv6 prefix 2001:db8:12d:1300::/64 to Ethernet
interface 3/1 and enable IPv6 IS-IS on the interface.
Syntax: ipv6 address ipv6-prefix/prefix-length [eui-64]
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 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 or unique local 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.
Syntax: [no] ipv6 router isis
To disable IPv6 IS-IS on an interface, use the no form of this command.
