Exercise 5.2 Routes from non-OSPF areas

Objective
Change the edge router to an ASBR and examine the LSAs that are exchanged throughout the
network.

Exercise
1. Examine the LSDB to see what types of LSAs it contains.

2. Remove the loopback interfaces on the edge router from OSPF.

echo "IP Configuration"
#--------------------------------------------------
interface "E6_C4"
address 172.17.2.2/30
port 1/1/1
exit
interface "system"
address 172.19.254.1/32
exit
#--------------------------------------------------
echo "OSPFv2 Configuration"
#--------------------------------------------------
ospf
router-id 172.19.254.1
area 0.0.0.4
interface "E6_C4"
exit
exit
exit

3. Configure the edge router as an ASBR, and create and apply an export policy to export the
loopback networks to OSPF. To create an export policy, use the following commands. For
more details, you can refer to the scalable IP network lab guide.

 To create a Routing Policy
config>router# policy-options

 To enter the edit mode for creating a policy option
config>router>policy-options# begin

 To name the routing policy
config>router>policy-options# policy-statement "EXPOL"

 To edit routing policy entries
config>router>policy-options>policy-statement# entry 10

 To define the routing protocol being advertised
config>router>policy-options>policy-statement>entry# from protocol
direct

 To define the action to be taken by the policy
action {accept | next-entry | next-policy | reject}
Example: config>router>policy-options>policy-statement>entry# action
accept

Alcatel-Lucent Interior Routing Protocols Lab Guide v2.3 32

 To save the configured policy-option
config>router>policy-options# commit

4. On the core router, verify that the routing table contains routes to your loopback
networks.

5. Check the LSDB and note the types of LSAs it contains.

6. Verify the operation of OSPF.

Verification
1. Verify your route policies by examining the OSPF tables on all routers.

2. Verify connectivity by issuing the traceroute and ping commands.

3. Use the OSPF show commands to examine the databases for accuracy.

4. How many routes are in your routing table?

Questions
1. Which type of router connects to non-OSPF routing domains?



2. Which types of LSAs exist in an OSPF network connected to other routing domains that are

not in an OSPF-only network?




Exercise 5.3 OSPF stub areas

Objective
Together with your instructor, choose two areas and convert them to an OSPF stub areas, and
then examine the differences in the routing table.

Exercise
1. Examine the LSDB to see what types of LSAs it contains, and verify the routes in the routing

table.

Alcatel-Lucent Interior Routing Protocols Lab Guide v2.3 33

2. Remove the export policy from your edge router so it is no longer flooding Type 5 LSAs.
Convert your area to a stub area.
