Configuring an IPv6 address on the SLX platform

Following are the basic pre-requisites for configuring an IPv6 address on the SLX platform:

PC connected to the serial port of the device.
IPv6 network assignment with a netmask and router address from the network administrators. This will generally be a /64 network.

Note

If you are provided an IPv6 prefix with a /65 to /128 net mask, assign the addresses according to your network administrator's direction, and do NOT follow this procedure.

To configure IPv6 addresses, perform the following steps:

Enter the show system command to know the STACK MAC and the BURNED IN MAC.

SLX# show system
Stack MAC                     : 60:9c:9f:de:29:14

  -- UNIT 0 --
Unit Name                     : SLX
Up Time                       : up 11 days
Current Time                  : 10:41:45 GMT
SLX-OS Version                : 20.4.1
Jumbo Capable                 : yes
Burned In MAC                 : 60:9c:9f:46:e2:06
Management IP                 : 10.20.131.53
Management Port Status        : UP

The MAC addresses are used to create the IPv6 SLAAC address for the following mapping:

Stack MAC - IPv6 address for chassis virtual-ipv6.

Convert each MAC address to a modified EUI-64 format, and then into the final IPv6 address for the interfaces by performing the following steps:
1. Remove any punctuation from the MAC.
```
609c9f46e206
```
2. Insert fffe after the first 6 characters.
```
609c9ffffe46e206
```
3. Using a calculator application in HEX Mode on a PC, do a Bitwise OR operation of the modified MAC with 0200000000000000.
```
629c9ffffe46e206
```
4. Convert the result to IPv6 format by inserting colons after every 4 characters from the right hand side.
```
629c:9fff:fe46:e206
```
5. Prepare the IPv6 network information for use. This example uses a sample network of 2001:DB8::/32 provided by the Admin.
  - Normalize the address to a fully expanded format.
```
2001:0DB8:0000:0000:0000:0000:0000:0000/32
```
  - Remove the cider notation.
```
2001:0DB8:0000:0000:0000:0000:0000:0000
```
  - Remove the host portion of the address based on a /64 netmask.
```
2001:0DB8:0000:0000:
```
  - Contract the remaining portion of the address of any leading zeros.
```
2001:DB8::
```
6. Combine the IPv6 network prefix from step 2e and the result of step 2d to make the IPv6 address.
```
2001:DB8::629c:9fff:fe46:e206/32
```
7. Repeat steps 2a to 2f for each MAC address.
Apply the addresses to the appropriate interfaces and configure the default route using the router address provided by the network administrator.
