7.2.2 Host Route Test
Scenario
As shown in Figure 7-2, Network Device A and Target Host B are connected to the IP network.
If both the network device and the target host are connected to the IP network, the host route test aims to check gateways (or
routers) that IP packets pass through between the two ends. Generally, the target host is not within the same IP network
segment as the network device.
Figure 7-2
Deployment
Execute the traceroute function on the network device.
7.3 Features
