n of the IP address for interface vlan3
Switch5(config)# interface vlan 3
Switch5(config-if-vlan3)# ip address 30.1.1.1 255.255.255.0
Switch5(config-if-vlan3)#no shutdown
Switch5(config-if-vlan3)#exit
Enable OSPF protocol, configure the number of the area in which interface vlan2 and vlan3
reside in.
Switch5(config)#router ospf

Typical complex OSPF autonomous system
This scenario is a typical complex OSPF autonomous system network topology. Area1 include
network N1-N4 and Layer 3 SwitchA-SwitchD, area2 include network N8-N10, host H1 and
Layer 3 SwitchH, area3 include N5-N7 and Layer 3 SwitchF, SwitchG SwitchA0 and Switch11,
and network N8-N10 share a summary route with host H1(i.e. area3 is defined as a STUB
area). Layer 3 SwitchA, SwitchB, SwitchD, SwitchE, SwitchG, SwitchH, Switch12 are in-area
Layer 3 switches, SwitchC, SwitchD, SwitchF, Switch10 and Switch11 are edge Layer 3
switches of the area, SwitchD and SwitchF are edge Layer 3 switches of the autonomous
system.
