• For IPv4: Define an OSPF router. Define Area 1 as a stub. Enable OSPF for IPv4 on interfaces 10, 5, and 17 by globally defining the range of IP addresses associated with each interface, and then associating those ranges with Areas 1, 0, and 17, respectively. Then, configure a metric cost to associate with static routes when they are redistributed via OSPF: router ospf router-id 2.2.2.2 area 0.0.0.1 stub area 0.0.0.2 nssa network 10.1.2.0 0.0.0.255 area 0.0.0.1 network 10.2.3.0 0.0.0.255 area 0.0.0.0 network 10.2.4.0 0.0.0.255 area 0.0.0.2 redistribute static metric 1 subnets exit • For IPv6: Define an OSPF router. Define Area 1 as a stub and area 2 as a Not-So-Stubby-Area (NSSA). Configure a metric cost to associate with static routes when they are redistributed via OSPF: ipv6 router ospf router-id 2.2.2.2 area 0.0.0.1 stub area 0.0.0.2 nssa redistribute static metric 105 metric-type 1 exit exit Example 3: Configuring a Virtual Link In this example, Area 0 connects directly to Area 1. A virtual link is defined that traverses Area 1 and connects to Area 2. Figure 4-5 illustrates this example OSPF configuration. 74 Routing Configuration

Routing Configuration
•
For IPv4: Define an OSPF router. Define Area 1 as a stub. Enable OSPF for IPv4 on interfaces 10, 5,
and 17 by globally defining the range of IP addresses associated with each interface, and then
associating those ranges with Areas 1, 0, and 17, respectively. Then, configure a metric cost to associate
with static routes when they are redistributed via OSPF:
router ospf
router-id 2.2.2.2
area 0.0.0.1 stub
area 0.0.0.2 nssa
network 10.1.2.0 0.0.0.255 area 0.0.0.1
network 10.2.3.0 0.0.0.255 area 0.0.0.0
network 10.2.4.0 0.0.0.255 area 0.0.0.2
redistribute static metric 1 subnets
exit
•
For IPv6: Define an OSPF router. Define Area 1 as a stub and area 2 as a Not-So-Stubby-Area (NSSA).
Configure a metric cost to associate with static routes when they are redistributed via OSPF:
ipv6 router ospf
router-id 2.2.2.2
area 0.0.0.1 stub
area 0.0.0.2 nssa
redistribute static metric 105 metric-type 1
exit
exit
Example 3: Configuring a Virtual Link
In this example, Area 0 connects directly to Area 1. A virtual link is defined that traverses Area 1 and
connects to Area 2.
Figure 4-5 illustrates this example OSPF configuration.
