passive-interface Loopback1
The HQ router needs to send the default route information to the Branch1 and Branch2
routers in the OSPF updates. What command is used to configure this?
default-information originate
Task 9: Configure OSPF Routing on the Branch2 Router
Consider the networks that need to be included in the OSPF updates that are sent out by the Branch2
router.
What directly connected networks are present in the Branch2 routing table?
172.20.48.0/21
172.20.56.4/30
172.20.56.8/30
What commands are required to enable OSPF and include the connected networks in the routing
updates?
router ospf 1
network 172.20.48.0 0.0.7.255 area 0
network 172.20.56.4 0.0.0.3 area 0
network 172.20.56.8 0.0.0.3 area 0
Are there any router interfaces that do not need to have OSPF updates sent out? Yes
What command is used to disable OSPF updates on these interfaces?
passive-interface FastEthernet0/0
Task 10: Verify the Configurations
Answer the following questions to verify that the network is operating as expected.
From PC1, is it possible to ping PC2? Yes
From PC1, is it possible to ping PC3? Yes
The answer to these questions should be yes . If any of these pings failed, check your physical connec-
tions and configurations. Refer to your basic troubleshooting techniques used in the Chapter 1 labs.
