layer3 SwitchD interface VLAN2 is 10.1.1.4. SwitchA is connecting to network N1 through Ethernet interface
VLAN1 (IP address 20.1.1.1); SwitchB is connecting to network N2 through Ethernet interface VLAN1 (IP
address 20.1.2.1); SwitchC is connecting to net work N4 through Ethernet interface VLA N3 (IP address
20.1.3.1). All the three addresses belong to area 1. SwitchC is connecting to layer3 SwitchE through Ethernet
interface VLA N1 (IP address 10.1.5.1); SwitchD is connecting to layer3 SwitchD through Ethernet interface
VLAN1 (IP address 10.1.6.1); both two addresses belong to area 1. Simple authentication is implemented
among layer3 switches in area1, edge layer3 switches of area 1 authenticate with the area 0 backbone layer3
switches by MD5 authentication.
The followings are just configurations for all layer3 switches in area 1, configurations for layer3 switches of the
other areas are omitted. The following are the configurations of SwitchA SwitchB.SwitchC and SwitchD:
1)SwitchA:
Configure IP address for int erface vlan2
SwitchA#config
SwitchA(config)# interface vlan 2
SwitchA(config-If-Vlan2)# ip address 10.1. 1.1 255.255.255.0
SwitchA(config-If-Vlan2)#exit
Enable OSPF protocol, configure the area number for interface vlan2.
SwitchA(config)#router ospf
SwitchA(config-router)#net work 10.1.1.0/24 area 1
SwitchA(config-router)#exit
Configure simple key authentication.
SwitchA(config)#int erface vlan 2
SwitchA(config-If-Vlan2)#ip ospf authentication
SwitchA(config-If-Vlan2)#ip ospf authentication-key DCS
SwitchA(config-If-Vlan2)exit
Configure IP address and area number for interfac e vlan1.
SwitchA(config)# interface vlan 1
SwitchA(config-If-Vlan1)#ip address 20.1.1.1 255.255.255.0
SwitchA(config-If-Vlan1)#exit
SwitchA(config)#router ospf
SwitchA(config-router)#net work 20.1.1.0/24 area 1
SwitchA(config-router)#exit
2)SwitchB:
Configure IP address for int erface vlan2
SwitchB#config
SwitchB(config)# interface vlan 2
SwitchB(config-If-Vlan2)# ip address 10.1. 1.2 255.255.255.0
SwitchB(config-If-Vlan2)#exit
