HP-UX Routing Services Administrator's Guide HP-UX 11i v2, HP-UX 11i v3 (B2355-91153, November 2011)

pollinterval must be larger than the value of hellointerval. A sample value for an
X.25 network is 2 minutes.
◦ Default: None (you must specify a value)
◦ Range: 0 – 255
• routers specify the list of routers attached to the non-broadcast network. Routers are defined
by their IP interface addresses. You must define the routers that are eligible to be designated
routers as eligible.
Figure 10 shows an example of a router (A) that is connected to an NBMA network through the
interface 193.2.1.35. Two other routers are also attached to the network: router B is connected
through the interface 193.2.1.33 and C is connected through the interface 193.2.1.46. B and C
are eligible to be designated routers.
Figure 10 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 time interval (in seconds) between the retransmission of link
states, database descriptions, and link state request packets. This value must exceed the
expected round-trip delay between any two routers in the network. A sample value for a LAN
is 5 seconds.
◦ Default: None (you must specify a value)
◦ Range: 0 – 65535
• hellointerval specifies the time interval (in seconds) between transmission of OSPF Hello
packets. Smaller intervals ensure that changes in network topology are detected faster. A
sample value for an X.25 network is 30 seconds. A sample value for a LAN is 10 seconds.
◦ Default: None (you must specify a value)
◦ Range: 0 – 255
