In IPv6 network, an IPv6 overlay tunnel is required to communicate with isolated IPv6 networks across the existing IPv4 infrastructurE. There are currently fiv e IPv6 overlay tunnel types.
Which three IPv6 overlay tunnel statements are true？（）
A. Overlay tunnels can only be configured between border routers capable of supporting IPv4 and IPv6.
B. An manual overlay tunnel supports point - to - multipo int tunnels capable of carrying IPv6 and Connectionless Network Service (CLNS) packets.
C. Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.
D. Overlay tunnels can be configured between border route rs or between a border router and a host capable of supporting IPv4 and IPv6.
E. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4 - compatible, 6to4, and Intra - Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechan isms.
F. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv6 - compatible, 4to6, and Multiprotocol Label Switching (MPLS) overlay tunneling mechanisms.
A. An automatic 6to4 tunnel does not req uire dual - stack (IPv4 and IPv6) routers at the tunnel endpoints.
B. An automatic 6to4 tunnel allows multiple IPv4 destinations.
C. A manually configured IPv6 in IPv4 tunnel allows multiple IPv4 destinations.
D. A manually configured IPv6 in IPv4 tunnel does not require dual- stack (IPv4 and IPv6) routers at the tunnel endpoints.
A. IPv6 allows a host to create its own IPv6 address that will allow it to communicate to other devices on a network configured via DHCP. IPv4 does not provide a similar capability for hosts.
B. IPv6 provides for more host IP addresses but IPv4 provides for more network addresses.
C. Hosts can be configured to receive both IPv4 and IPv6 addresses via DHCP.
D. Host configuration options for IPv4 can be either statically assigned or assigned via DHCP.Host configuration options for IPv6 can be statically assigned only.
E. IPv4 and IPv6 addresses c an be simultaneously assigned to a host but not to a router interface.
Refer to the exhibit. IP multicast configuration changes have been made on several routers.However, the IP multicast table displayed in the exhibit still does not reflect the changes. What should be done to display the new routing table information? （）
A. Issue the clear ip route * privileged EXEC command.
B. Issue the clear ip igmp group privileged EXEC command.
C. Issue the no ip mroute - cache privileged EXEC command.
D. Issue the clear ip mroute privileged EXEC command.
