Scenario
Refer to the topology. Your company has decided to connect the main office with three other
remote branch offices using point-to-point serial links.
You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main
office and the routers located in the remote branch offices.

An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the Branch3
office. What is causing the problem?

CORRECT TEXT

CORRECT TEXT
There are three locations in a school district of a large city: ROUTER -M, ROUTER -W and
ROUTER -U. The network connection between two of these locations has already functioned.
Configure the ROUTER -M router IP addresses on the E0 and S0 interfaces so that the E0

receives the first usable subnet while the S0 receives the second usable subnet from the network
192.168.160.0/28. Both interfaces would receive the last available ip address on the proper
subnet.

NotE. The OSPF process must be configured to allow interfaces in specific subnets to
participate in the routing process.

CORRECT TEXT

This topology contains 3 routers and 1 switch. Complete the topology.
Drag the appropriate device icons to the labeled Device
Drag the appropriate connections to the locations labeled Connections.
Drag the appropriate IP addresses to the locations labeled IP address
(Hint: use the given host addresses and Main router information)
To remove a device or connection, drag it away from the topology.
Use information gathered from the Main router to complete the configuration of any additional
routers.
No passwords are required to access the Main router. The config terminal command has been
disabled for the HQ router. The router does not require any configuration.

Configure each additional router with the following:
Configure the interfaces with the correct IP address and enable the interfaces.

Set the password to allow console access to consolepw
Set the password to allow telnet access to telnetpw
Set the password to allow privilege mode access to privpw
NotE. Because routes are not being added to the configurations, you will not be able to ping
through the internetwork.
All devices have cable autosensing capabilities disabled.
All hosts are PC’s
