A. B. C. D. E.AB
The tunnel mode ipv6ip
command is used to configure a tunnel interface in Cisco devices to transmit IPv6 traffic over an IPv4 network. Here are the two statements that are true about this command:
A. It enables the transmission of IPv6 packets within the configured tunnel.
This statement is true because the tunnel mode ipv6ip
command specifies that the tunnel interface will transport IPv6 packets over an IPv4 network. Without this command, the router would not know how to encapsulate the IPv6 packets and transmit them over the IPv4 network.
C. It specifies IPv6 as the encapsulation protocol.
This statement is also true because the tunnel mode ipv6ip
command specifies that the encapsulation protocol for the tunnel is IPv6. This means that the IPv6 packets will be encapsulated within IPv4 packets before they are transmitted over the network.
B, D, and E are incorrect:
B. It specifies IPv4 as the encapsulation protocol.
This statement is false because the tunnel mode ipv6ip
command specifies that the encapsulation protocol for the tunnel is IPv6, not IPv4.
D. It specifies IPv6 as the transport protocol.
This statement is false because the tunnel mode ipv6ip
command does not specify the transport protocol for the tunnel. It only specifies the encapsulation protocol, which is IPv6.
E. It specifies that the tunnel is a Teredo tunnel.
This statement is false because the tunnel mode ipv6ip
command does not specify the type of tunnel that is being configured. It only specifies the encapsulation protocol, which is IPv6.
In summary, the tunnel mode ipv6ip
command is used to enable the transmission of IPv6 packets within a configured tunnel and to specify IPv6 as the encapsulation protocol.
