Switch A becomes the DR, and Switch C is the BDR. 
The full neighbor state means an adjacency has been established. The  2-way neighbor state 
means the two routers are not the DR or BDR, and they do not exchange LSAs.

Configuration procedure 
1. Configure IP addresses for inte rfaces. (Details not shown.) 
2. Configure OSPF basic functions: 
# Configure Switch A.

Area 0 has no direct connection to Area 2, so the routing table of Switch B has no route to Area 
2. 
3.  Configure a virtual link: 
# Configure Switch B.

Configuring route filtering 
Network requirements 
As shown in Figure 46: 
•   A
ll the switches in the network run OSPF. The AS is divided into three areas.  
•   Switch A and Switch B work as ABRs.  
Configure Switch C as an ASBR to redistribute external  routes (static routes), and configure a filter policy 
on Switch C to filter out redistributed route 3.1.3.0/24.  
Configure a routing policy on Switch A to filter route 10.5.1.0/24.
