Lab 1 -- Connecting to the IPv6 internet

One person uses one Router and one PC. No groups!
You may talk to each other, though.

Topology

A) Router connectivity

1. Connect your router to the CNAP-switch, which in turn connect to the CNAP-Brouter for L3-Routing
2. Enable plug-and-play IPv4 addressing on your router-port
3. What IPv4 address (and default gateway did you get ?)
4. Enable plug-and-play IPv6 addressing on your router-port
5. What IPv6 address (and default gateway did you get ?)
6. traceroute to 2001:6b0:1d:10::11, how many router-hops?
7. Define DNS-server as 2001:6b0:1d:10::11
8. How many router-hops is it to www.facebook.com?
9. Found any fun IPv6-addresses (leet-speak!?!)
10. Is there any difference between "a connection on port 1-6 in the CNAP-switch" and "a connection on port 7-23 in the CNAP-switch"?

    What or Why Not?

WARNING: Do not configure link-local address FE80::1 -- Every other group might use the same address!
Use FE80::c2 where c is your pod, and 2 is your PC's number

B) Basic EIGRP

1. Enable ipv6 eigrp 1 and make sure that you become a neighbor with CNAP-brouter
2. Every group (POD) gets 16 IPv6 subnets 2001:6b0:1d:1x0/60 where x is the POD-letter
   

Example: POD C's third network would be 2001:6b0:1d:1C2/64

1. How many other groups have announced networks according to the routing table?
2. Create a loopback interface with a IPv6 address and announce it over EIGRP
3. Go to another group and check if they can see your network in their routing table?
4. Can you traceroute to the other group
5. Try also ping, but it's boring...
6. If you are into routing; create more loopbacks and try to summarize them. Don't steal networks from other PODS!

   No prob's if you want to jump this point, and skip to the next one

C) Client IPv6 Connectivity

1. Connect your PC directly to the "internet" and download [www.teeworlds.com], then disconnect.
2. Disconnect your PC from the internet (:-)
3. Connect your pc to the other router ethernet port
4. Make sure that your router ethernet interfaces are UP/UP
5. Configure static IPv6 addresses (global and link-local) on the router interface facing the PC
6. Configure static global IPv6 addressing on the PC (IP,mask + default gateway and DNS)

   DNS addresses are 2001:6b0:1d:10::11 and 2001:6b0:1d:10::12

7. Can you TRACERT to ipv6.google.com? why?
8. Can you TRACERT to www.volvo.com? why?
9. Can you surf to ipv6.google.com?
10. Can you surf to http://www.volvo.com/ ?
11. Can you surf to http://www.volvo.com.sixxs.org/ through the Application Level Gateway (ALG) of sixXS ?
12. Set up a teeworlds server and invite your friends
13. Remove your PC addressing configuration
14. Enable stateless autoconf (SLAAC) of your PC on the router
15. What address did your PC get? why not eui64?
16. Test teeworlds again
17. Enable stateful autoconf (DHCPv6) of your PC on the router and try to give the PC the shortest possible IPv6-address.
18. Try IPCONFIG /RELEASE6 and /RENEW6 etc on the PC
19. Play some teeworlds until you want to go home... (:-)

Good Luck /Robert

BGP -- Do not even try

• Create IPv4 connectivity between two router
• Become ipv4 BGP neighbours
• Announce Loopback IPv6 networks over the ipv4 link, using BGP address family IPv6

Create L3 connectivity and try ping
