Task 4: Troubleshoot the HQ Router
Begin troubleshooting at the host connected to the R2 router.
Step 1.
From the host PC2, is it possible to ping PC1?
no
From the host PC2, is it possible to ping PC3?
no
From the host PC2, is it possible to ping the default gateway?
yes
Examine the HQ router to find possible configuration errors.
Step 2.
Begin by viewing the summary of status information for each interface on the router.
Are there any problems with the status of the interfaces?
no
If there are any problems with the status of the interfaces, record any commands that will
be necessary to correct the configuration errors.
If you have recorded any commands, apply them to the router configuration now.
Step 3.
View the summary of the status information.
Step 4.
If any changes were made to the configuration in the previous step, view the summary of
the status information for the router interfaces again.
Does the information in the interface status summary indicate any configuration errors?
no
If the answer is
yes
, troubleshoot the interface status of the interfaces again.
Troubleshoot the routing configuration on the HQ router.
Step 5.
What networks are shown in the routing table?
0.0.0.0/0
10.0.0.0/24
192.168.1.0/24
172.20.20.0/24
Are there any problems with the routing table?
no
If there are any problems with the routing table, record any commands that will be neces-
sary to correct the configuration errors.
What networks are included in the RIP updates?
0.0.0.0
10.45.1.0
192.168.1.0
Are there any problems with the RIP updates that are being sent out from the router?
Routing updates are not being sent out of the Serial 0/0/0 interface because of the
passive-
interface Serial 0/0
command. This command should be replaced by the
passive-inter-
face FastEthernet0/0
command.
If there are any problems with the RIP configuration, record any commands that will be
necessary to correct the configuration errors.
