Refer to the below topology and the scripts (see the below Figure) for configuring single-area OSPF routing on the three routers. These scripts contain up to three errors that will prevent end-to-end communication across the whole network. Determine these errors, and use the appropriate Cisco IOS commands to correct them, so that all of the hosts on the network can communicate with each other. 172.18.64.0/18 router ospf 1 network 192.168.254.244 0.0.0.3 area 0 network 192.168.254.248 0.0.0.3 area 0 Fa0/0 network 172.18.64.0 0.0.63.255 area 1 S0/0/0 R2 S0/0/1 DCE 192.168.254.244/30 172.18.129.0/28 S0/0/0 DCE Single-Area OSPF 192.168.254.248/30 S0/0/1 172.18.128.0/24 Fa0/0 Fa0/1 Fa0/1 Fa0/0 R1 R3 192.168.254.64/26 router ospf 1 network 192.168.254.244 0.0.0.3 area 0 network 192.168.254.64 0.0.0.31 area 0 network 172.18.129.0 0.0.0.15 area 0. router ospf 5 network 192.168.254.248 0.0.0.3 area 0 network 172.18.128.0 0.0.0.255 area 0 Refer to the below topology and the scripts (see the below Figure) for configuring single-area OSPF routing on the three routers.
