Area 0 has no direct connection to Area 2, so the OSPF routing table of Router B has no route to
Area 2.
3. Configure a virtual link:
# Configure Router B.
[RouterB] ospf
[RouterB-ospf-1] area 1
[RouterB-ospf-1-area-0.0.0.1] vlink-peer 3.3.3.3
[RouterB-ospf-1-area-0.0.0.1] quit
[RouterB-ospf-1] quit
# Configure Firewall.
[Firewall] ospf
[Firewall-ospf-1] area 1
[Firewall-ospf-1-area-0.0.0.1] vlink-peer 2.2.2.2
[Firewall-ospf-1-area-0.0.0.1] quit
# Display OSPF routing information on Router B.
[RouterB] display ospf routing
OSPF Process 1 with Router ID 2.2.2.2

Router B has learned the route 10.3.1.0/24 to Area 2.
Route filtering configuration example
Network requirements
• In Figure 277, all the routers in the network run OSPF. The AS is divided into three areas.
• Router A works as the ABR between Area 0 and Area 1. Router B works as the ABR between Area
0 and Area 2.
• Configure Firewall as an ASBR to redistribute external routes (static routes), and configure a filter
policy on Firewall to filter out route 3.1.3.0/24.
• Configure a routing policy on Router A to filter route 10.5.1.0/24.
