Refer to the exhibit. An engineer configured the New York router with state routes that point to the Atlanta and Washington sites. When command must be configured on the Atlanta and Washington routers so that both sites are able to reach the loopback2 interface on the New York router?
- A. ipv6 route ::/0 Serial 0/0/1
- B. ipv6 route 0/0 Serial 0/0/0
- C. ipv6 route ::/0 Serial 0/0/0
- D. ip route 0.0.0.0.0.0.0.0 Serial 0/0/0
- E. ipv6 route ::/0 2000::2
Correct Answer: C

To enable the Atlanta and Washington sites to reach the loopback2 interface on the New York router, a default route pointing to the New York router needs to be added on the Atlanta and Washington routers. Since the New York router is directly connected to the Atlanta and Washington routers via their Serial 0/0/0 interfaces, the command to configure a default route on these routers should point to the Serial 0/0/0 interface of the New York router.
The correct command to add a default route in IPv6 is “ipv6 route ::/0 <next-hop-IPv6-address or exit-interface>”.
In this case, the command that must be configured on the Atlanta and Washington routers is:
ipv6 route ::/0 Serial 0/0/0
This command tells the Atlanta and Washington routers to forward all IPv6 traffic that doesn’t match a more specific route to the Serial 0/0/0 interface of the New York router, which is directly connected. This will enable the Atlanta and Washington sites to reach the loopback2 interface on the New York router.
Option A is incorrect because it specifies an invalid exit interface.
Option B is incorrect because it specifies an invalid IPv6 address.
Option D is incorrect because it specifies an IPv4 command and syntax.
Option E is incorrect because it specifies the loopback interface address of the New York router instead of the Serial 0/0/0 interface.

Shouldn’t it be the E ?? It says “both sites are able to reach the loopback2 interface on the New York router” not serial …
