Figure 8-7 Non-Broadcast Router Interface Example
The following is an example of the non-broadcast interface definition in
router A’s /etc/gated.conf file:
interface 193.2.1.35 nonbroadcast cost 5 {
routers {
193.2.1.33 eligible ;
193.2.1.46 eligible ;
} ;
priority 15 ;
hellointerval 5 ;
routerdeadinterval 20 ;
retransmitinterval 10 ;
pollinterval 20 ;
} ;
Point-to-Point Interfaces. On point-to-point networks, an OSPF
router dynamically detects its neighbor router by sending OSPF Hello
packets. The following statements are defined for a point-to-point
interface:
retransmitinterval is the number of seconds between
retransmission of link states, database description, and link state
request packets. This value should exceed the expected round-trip delay
between any two routers in the network. A sample value for a LAN is 5
seconds.
