Samuel has been asked to start the implementation of IPv6 on an existing IPv4 network. The current system has no native connection to an IPv6 network. It has about 130 hosts. The internal routing protocol is OSPF. Which technology would you recommend that Samuel use? A. VRRP B. Teredo C. 802.1AE D. 6to4 Solution D. 6 to 4 because it is the mechanism that allows IPv6 package to transmit over IPv4 network without need of configure tunnels. 6 to 4 network can communicate with native IPv6 networks with the help of special relay server. working of 6to4: 1. assign a block of IPv6 address space to any host or network that has a global IPv4 address. 2. encapsulate IPv6 package inside IPv4 for transmission over IPv4 using 6to4 network. 3. it routes the traffic between native IPv6 and 6to4 network .

routing protocol is OSPF. Which technology would you recommend that Samuel use?
A. VRRP
B. Teredo
C. 802.1AE
D. 6to4
Solution
D. 6 to 4 because it is the mechanism that allows IPv6 package to transmit over IPv4 network
without need of configure tunnels. 6 to 4 network can communicate with native IPv6 networks
with the help of special relay server.
working of 6to4:
1. assign a block of IPv6 address space to any host or network that has a global IPv4 address.
2. encapsulate IPv6 package inside IPv4 for transmission over IPv4 using 6to4 network.
3. it routes the traffic between native IPv6 and 6to4 network
