10.2.4.4Blocking Transmission of Route Information Database

OSPF routing communicates through the LAS. Each routing information is saved internal router as a datebase, but user can configure the specific interface to block the transmis- sion of routing information saved in database to other router.

To block the transmission of routing information to other router, use the following com- mand.

Command	Mode	Description
ip ospf database-filter all out		Blocks the transmission of routing information to other
	Interface
ip ospf A.B.C.D database-filter
		router.
all out

To release a blocked interface, use the following command.

Command	Mode	Description
no ip ospf database-filter
	Interface	Releases a blocked interface.
no ip ospf A.B.C.D database-
filter

10.2.4.5Routing Protocol Interval

Routers on OSPF network exchange various packets, about that packet transmission, time interval can be configured in several ways

The following lists are sort of time interval which can be configured by user:

•Hello Interval

OSPF router sends Hello packet to notify existence of itself. Hello interval is that packet transmission interval.

•Retransmit Interval

When router transmits LSA, it is waiting for approval information come from receiver. In this time, if there is no answer from receiver for configured time, the router trans- mits LSA again. Retransmit-interval is configuration of the time interval between transmission and retransmission.

•Dead Interval

If there is no hello packet for the configured time. The router perceives other router is stopped working. Dead interval is configuration of the time interval which perceives other router is stopped operating.

•Transmit Delay

When a router transmits LSA, the traffic can be delayed by status of communications.
