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?
teeworlds
- 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. Remember to use literal IPv6 addresses, IPv6 addresses enclosed in square brackets [ ] , when connecting to the server
- 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

Brouter Config stateful IPv6 DHCP
The RA contains several flags that are set that the nodes watch for and use.
A-bit – Autonomous Address Autoconfiguration Flag tells the node it should perform stateless address assignment (SLAAC RFC 4862) L-bit – On-Link Flag tells the node that the prefix listed in the RA is the local IPv6 address M-bit – Managed Address Config Flag tells the host if it should use stateful DHCPv6 (RFC 3315) to acquire its address and other DHCPv6 options O-bit – Other Config Flag tells the host that there is other information the router can provide (such as DNS information defined in Stateless DHCPv6 (RFC 3736))

Good Documentation ?!? =
According to http://www.litech.org/6rd/ (Linux 6RD HOWTO)
Är detta en bättre guide ?? https://ipv6akuten.se/?page_id=435
Once you have the 6RD parameters, you can determine your delegated prefix. This is the IPv6 address block you will be using for your local network.
The delegated prefix is constructed by appending your ISP-assigned IPv4 address to the 6RD prefix. For example, if your 6RD prefix is 2001:db8::/32, your ISP-assigned IPv4 address is 192.0.2.100, and your home network is connected to your router on interface eth0, you would configure your LAN address as follows:
# printf "%02x%02x:%02x%02x\n" 192 0 2 100 c000:0264 # ip addr add 2001:db8:c000:0264::1/64 dev eth0 #
Bredb 2001:09c8::/32 gives
# ifconfig eth0 | grep "inet addr"
inet addr:212.3.7.48 Bcast:212.3.7.63 Mask:255.255.255.224
# printf "%02x%02x:%02x%02x\n" 212 3 7 48
d403:0730
# ip addr add 2001:09c8:d403:0730::1/64 dev eth0
Next, you will need to bring up the 6RD tunnel interface. Assuming your ISP's 6RD border router is at 1.2.3.4:
# ip tunnel add 6rd mode sit local 192.0.2.100 ttl 64 # ip tunnel 6rd dev 6rd 6rd-prefix 2001:09c8::/32 # ip addr add 2001:09c8:d403:0730::1/32 dev 6rd # ip link set 6rd up # ip route add ::/0 via ::1.2.3.4 dev 6rd #
That's it! Your border router should now be able to ping IPv6 addresses such as ipv6.google.com.
