Task 1

Configure IPv6 network addresses as follows:

• R1's FastEthernet0/1 = 2001:0:0:D7::/64
• R2's FastEthernet0/0 = 2001:0:0:1B::/64

Ensure that the host id is created automatically (off of a router's MAC address)

Task 2

Enable RIPng with the identifier 'CCIE' allowing traffic between Vlan 27 and Vlan 215. Ensure that R1 and R2 can ping their respective Vlans using router's host names as well. Assume there is no IPv6 DNS server in the network.

Solution

Lunch break at work and I am playing in the lab. How geeky am I?

Notice!

You don't have to enable RIPng process in the global config mode. You can enable it directly on the interface(es) instead. The global process will start automatically.

In order to ping the routers by their names without DNS service, you must create ip host mappings (hosts). Your IPv6 addresses will be different than mine here:

R2's Fa0/0 IPv6 address = 2001::1B:C001:AFF:FE16:0

R1's Fa0/1 IPv6 address = 2001::D7:C000:AFF:FE16:1

R1 Config:

!

ipv6 host R2 2001::1B:C001:AFF:FE16:0

!

R2 Config:

!

ipv6 host R1 2001::D7:C000:AFF:FE16:1

!

Verification:

#show hosts

Ping works!
