Troubleshoot problems introduced by incorrect configurations.Step 1a) Disable Simple mode and Auto DHCP mode.b) Enable Console mode and Auto D
2、HCP mode.c) Open a terminal session to the routers and verify the routers configurations by performing a show running-config on each router. If not correct, fix any configuration errors and verify. Step 2a) The following is the configuration for the host connected to the GAD Router, configure the de

Correct the configurations to allow the packet to reach its destination.What

Configure static and
7、default routes between routers to allow data transfer between routers without the use of dynamic routing protocols. b. IP addresses and subnet masks for each device have already been predefined. Step 1a) In simulation mode, send a packet from PC0 to PC2. Notice that the Sterling router failed to the
8、 packet to the next hop.Step 2a) While in simulation mode, open up a terminal session for each router. Check the routing tables for each router with the command: show ip route. Notice there are no routes for the other networks.Step 3a) In Topology Mode, open a terminal session for the Sterling route
9、r.b) Get into global configuration mode and add the following static routes:i. ip route 172.16.3.0 255.255.255.0 172.16.2.2ii. ip route 172.16.5.0 255.255.255.0 172.16.2.2iii. ip route 0.0.0.0 0.0.0.0 172.16.2.2c) In privileged exec mode, input copy run start to save the running-configuration to sta

Check the routing tables for each router with the command: show ip route. The static routes entered above should appear in the output.b) Doing a show running-config will also display the new static routes in the output.Step 5第 4 页 共 4 页a) In simulation mode, send a packet from PC0 to PC2. The packet will successfully propagate to PC2.
