Internetwork Expert Volume II: Lab 2 – Section 7

Section 7 – IPv6 – 4 Points

7.1 IPv6 Addressing

Very easy IPv6 configuration task.

“The host portion of the IPv6 addresses should be based partly off of their interfaces’ respective MAC addresses”

This should ring a very loud bell to use eui-64:

ipv6 address eui-64

Configuring IPv6 Addressing and Enabling IPv6 Routing

r2(config)#int fa0/0
r2(config-if)#ipv6 address 2001:CC1E:1:202::/64 eui-64
r2(config-if)#do sh int fa0/0 | i bia
  Hardware is AmdFE, address is 000d.bc01.3400 (bia 000d.bc01.3400)

2(config-if)#do sh ipv6 int br | sec Ethernet0/0
FastEthernet0/0            [up/up]
    FE80::20D:BCFF:FE01:3400
    2001:CC1E:1:202:20D:BCFF:FE01:3400

7.2 IPv6 Tunneling

Crap!  Tunneling is something that I have managed to put off studying.  Luckily if you can configure a GRE tunnel, you can easily complete this task as the sub-tasks pretty much step you through the process.

Oops:

r2#p FE80::20A:B7FF:FE57:3A41 <-r4’s tunnel address 😦
Output Interface: tu0
% Invalid interface. Use full interface name without spaces (e.g. Serial0/1)
Output Interface: s0/0
% Invalid interface. Use full interface name without spaces (e.g. Serial0/1)
Output Interface: Serial0/0
% IPv6 isn’t enabled on this interface
Output Interface: quit
% Invalid interface. Use full interface name without spaces (e.g. Serial0/1)
Output Interface:

I couldn’t break out of this — until I used cntl+c  🙂
