Configuring gated

 

Configuring the OSPF Protocol

 

Figure 3-9 shows an example of an area border router that is connected

 

to area 0.0.0.2 through interface 193.2.1.20. Because all traffic in and out

 

of the area 0.0.0.2 must pass through router A, it is not necessary for the

 

area’s internal routers, such as router B, to receive inter-area routing

 

information.

The following is an example of the stub area definition in the router’s /etc/gated.conf file:

OSPF yes { area 0.0.0.2 {

stub cost 5 ; networks {

193.2.1.16 mask 0xfffffff0 ;

};

interface 193.2.1.20 nonbroadcast cost 5 { enable ;

routers {

193.2.1.17eligible ;

};

priority 5 ; hellointerval 5 ; routerdeadinterval 20 ; retransmitinterval 10 ; pollinterval 20 ;

} ; } ;

};
