Router HW cannot access hosts in the remote network, router HW runs routing protocols and only pings the remote file server address 105401 on router HW with extensions through a default route remote network , the result of ping on the router HW is rendered as 'requ.' est time out', according to the above description, the error in the following analysis is ?

The next hop router for router HW did not reach the destination address

Router HW does not have a legitimate router to reach the destination address

Ping is successful, but congestion occurs on the path to the destination address

There is a firewall in the remote destination network, and the destination address can be reached without releasing ICMP traffic E. ICMP packets, but the destination device fails to reply

Question 497

Regarding IPv6 over IP4(19) road, the following statement is correct

The 6to4 automatic tunnel requires the use of a specific IP6 address segment, and the assigned address segment is preceded by 3ffe::/16

When configuring manual tunneling on the VRP platform, a Tunnel interface is generally created; When configuring automatic tunneling, a Vrua-Template interface is usually created

The ISATAP tunnel determines the destination IPV4 address of the tunnel based on the destination IP6 address.

All automatic tunnels encapsulate data in the same way.

Automatic tunneling has great advantages over manual tunneling, and manual tunneling will be phased out
