OSPF is configured on routers Amani and Lynaic. Amani's S0/0 interface and Lynaic"˜s S0/1 interface are in Area 0. Lynaic"˜s Loopback0 interface is in Area 2.
Your task is to configure the following:
Portland's S0/0 interface in Area 1 Amani's S0/1 interface in Area 1 Use the appropriate mask such that ONLY Portland's S0/0 and Amnani's S0/1 could be in
Area 1. Area 1 should not receive any external or inter-area routes (except the default route).
















 

Suggested Answer: See explanation below

+ Configure Portland router as a stub:
Portland#configure terminal -
Portland(config)#router ospf 1 -
Allow network 192.168.4.4/30 to join Area 1, notice that you have to convert subnet mask into wildcard mask:
Portland(config-router)#network 192.168.4.4 0.0.0.3 area 1
Configure Portland as a stub:
Portland(config-router)#area 1 stub
Portland#copy running-config startup-config
+ Configure Amani router as a "totally stub":
Amani#configure terminal -
Amani(config)#router ospf 1 -
Amani(config-router)#network 192.168.4.4 0.0.0.3 area 1
Make area 1 become a totally stubby area, notice that we can only use this command on ABR router:
Amani(config-router)#area 1 stub no-summary
Amani#copy running-config startup-config
