QUESTION 206
The two empty-configured MSR routers MSR-1 and MSR-2 are interconnected through their respective GE0/0, and their IP addresses are 192.168.1.2/30 and 192.168.1.1/30 respectively.
Then add the following configuration on both routers:
[MSR-ospf-1]area 0 [MSR-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3

QUESTION 212
There are two hops from the source device to the destination device. Use the tracert command to detect the path. When detecting the first hop, the source device sends a UDP packet with a TTL of 1 to the middle hop; when detecting the second hop, the source device sends a UDP packet with a TTL of 2, and the packet reaches the middle hop first, and the TTL is decremented When the message reaches the destination, the TTL will be decremented to 0. At this time, the destination device will send an ICMP_____ message to the source to inform the source device that it has tracked the destination address.
