Step 3.
View a 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 on
the Branch2 router?
no
If the answer is
yes
, troubleshoot the interface status of the interfaces again.
Troubleshoot the routing configuration on the Branch2 router.
Step 5.
What routes are shown in the routing table?
10.10.0.0/22 [110/129] via 172.16.7.9
10.10.4.0/23 [110/65] via 172.16.7.9
10.10.6.0/23 is directly connected
172.16.7.0 [110/128] via 172.16.7.9
172.16.7.4 is directly connected
172.16.7.8 is directly connected
0.0.0.0/0 [110/1] via 172.16.7.9
Are there any problems with the routing table?
The route to the HQ LAN is through the Branch1 router.
Use the
show running-configuration
,
show ip protocols
, and
show ip ospf neighbor
commands to view information about the OSPF configuration on the Branch2 router. Are
there any problems with the OSPF configuration?
The HQ router is not shown in the neighbor table.
The
passive-interface
command is configured to use the wrong interface.
The mask used in the
network
statement for the 10.10.6.0/23 LAN is incorrect.
If there are any problems with the OSPF configuration, record any commands that will be
necessary to correct the configuration errors.
