communications for the corporation internally, with partners, and with the Internet.

Implement a dual-stack backbone, or implement IPv4 tunnels between the sites.
37.
NAT-PT is required to provide net work address translation and protocol translation
between IPv6 and IPv4 hosts.
38.
If a dual-stack backbone is implemented, only the WAN routers require an IPv6-IPv4
dual stack. End hosts do not need a dual stack.
39.
No. All WAN routers still run the IPv4 stack, with two exceptions: the WAN routers at
Sites A and B. These routers speak IPv6 within their sites and speak IPv4 to the WAN.

“Do I Know This Already?” Quiz
1.
D. Only RIPv1 is a classful routing protocol. EIGRP, OSPF, IS-IS, and RIPv2 are class-
less routing protocols.
2.
C. You use an exterior gateway protocol (EGP) to receive Internet routes from a serv-
ice provider.
3.
A. RIPv2 is a classless distance-vector routing protocol.
4.
B. Distance-vector routing protocols send periodic updates.
5.
B. RIPng is a distance-vector routing protocol that is used in IPv6 networks.
6.
B. If bandwidth is used, the path with the highest bandwidth is selected. If cost is
used, the path with the lowest cost is selected.
