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
- Connect your router to the CNAP-switch, which in turn connect to the CNAP-Brouter for L3-Routing
- Enable plug-and-play IPv4 addressing on your router-port
- What IPv4 address (and default gateway did you get ?)
- Enable plug-and-play IPv6 addressing on your router-port
- What IPv6 address (and default gateway did you get ?)
- traceroute to 2001:6b0:1d:10::11, how many router-hops?
- Define DNS-server as 2001:6b0:1d:10::11
- How many router-hops is it to www.facebook.com?
- Found any fun IPv6-addresses (leet-speak!?!)
- 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
- Enable ipv6 eigrp 1 and make sure that you become a neighbor with CNAP-brouter
- 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
- How many other groups have announced networks according to the routing table?
- Create a loopback interface with a IPv6 address and announce it over EIGRP
- Go to another group and check if they can see your network in their routing table?
- Can you traceroute to the other group
- Try also ping, but it's boring...
- 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
- Connect your PC directly to the "internet" and download [www.teeworlds.com], then disconnect.
- Disconnect your PC from the internet (:-)
- Connect your pc to the other router ethernet port
- Make sure that your router ethernet interfaces are UP/UP
- Configure static IPv6 addresses (global and link-local) on the router interface facing the PC
- 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
- Can you TRACERT to ipv6.google.com? why?
- Can you TRACERT to www.volvo.com? why?
- Can you surf to ipv6.google.com?
- Can you surf to http://www.volvo.com/ ?
- Can you surf to http://www.volvo.com.sixxs.org/ through the Application Level Gateway (ALG) of sixXS ?
- Set up a teeworlds server and invite your friends
- Remove your PC addressing configuration
- Enable stateless autoconf (SLAAC) of your PC on the router
- What address did your PC get? why not eui64?
- Test teeworlds again
- Enable stateful autoconf (DHCPv6) of your PC on the router and try to give the PC the shortest possible IPv6-address.
- Try IPCONFIG /RELEASE6 and /RENEW6 etc on the PC
- 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
