IP Connectivity

Question Image

Refer to the exhibit.

IPv6 must be implemented on R1 to the ISP. The uplink between R1 and the ISP must be configured with a manual assignment, and the LAN interface must be self-provisioned. Both connections must use the applicable IPv6 networks.

Which two configurations must be applied to R1?

Choose two
  • A interface Gi0/0ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA03:/127
  • B interface Gi0/0ipv6 address 2001:db8:0:AFFF::/64 eui-64
  • C interface Gi0/1ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA02:/127
  • D interface Gi0/0ipv6 address 2001:db8:1:AFFF::/64 eui-64
  • E interface Gi0/1ipv6 address 2001:db8:0F1B:FCCB:ACCE:FCED:ABCD:FA00:/127
Explanation

The ISP-facing link is on Gi0/1 and must use a manually assigned address from the WAN prefix 2001:db8:0F1B:FCCB:ACCE:FCED:ACBD:FA0:/127. A /127 point-to-point subnet contains exactly the two endpoint addresses in that block, so ...:FA00/127 is valid while ...:FA02/127 is outside that subnet. The LAN-facing link is on Gi0/0 and must be self-generated from the LAN prefix 2001:db8:0:AFFF::/64, which is done with eui-64. Therefore Gi0/0 must use 2001:db8:0:AFFF::/64 eui-64, and Gi0/1 must use the manual /127 address ending in FA00.
