BThe router encapsulates the source and destination IP addresses with the sending router P address as the source and the neighbor IP address as the destination
CThe router replaces the original source and destination MAC addresses with the sending router MAC address as the source and neighbor MAC address as the destination
DThe router encapsulates the original packet and then includes a tag that identifies the source router MAC address and transmit transparently to the destination

Refer to the exhibit. Which two commands, when configured on router R1, fulfill these requirements? (Choose two.) Packets towards the entire network 2001:db8:2::/64 must be forwarded through router R2. Packets toward host 2001:db8:23::14 preferably must be forwarded through R3.
Choose 2 — select all that apply
AIpv6 route 2001:db8:23::/128 fd00:12::2
BIpv6 route 2001:db8:23::14/128 fd00:13::3
CIpv6 route 2001:db8:23::14/64 fd00:12::2
DIpv6 route 2001:db8:23::/64 fd00:12::2
EIpv6 route 2001:db8:23::14/64 fd00:12::2 200
Correct Answer:BD
Therefore, we use a host route meaning that all bits of the ipv6 destination address must match (prefix-length of /128). Also, the next hop address should be that of R3 (fd00:13::3) since the question asks that packets for the host must be forwarded through it.
