• Dead timer-Interval within which if the interface receives no hello packet from the neighbor, it declares the neighbor is down. The dead interval must be at least four times the hello interval on an interface. • LSA retransmission timer-Interval within which if the interface receives no acknowledgement packets after sending an LSA to the neighbor, it retransmits the LSA. An interval setting that is too small can cause unnecessary LSA retransmissions. This interval is typically set bigger than the round-trip time of a packet between two neighbors. To configure timers for OSPF packets: Step 1. Enter system view. 2. Enter interface view. Command system-view interface interface-type interface-number 3. Specify the hello interval. ospf timer hello seconds 4. Specify the poll interval. ospf timer poll seconds 5. Specify the dead interval. ospf timer dead seconds 6. Specify the retransmission interval. ospf timer retransmit interval Remarks N/A N/A Optional. The hello interval defaults to 10 seconds on P2P and broadcast interfaces, and defaults to 30 seconds on P2MP and NBMA interfaces. The default hello interval is restored when the network type for an interface is changed. Optional. The poll interval defaults to 120 seconds. Optional. The default dead interval is 40 seconds on P2P and broadcast interfaces and 120 seconds on P2MP and NBMA interfaces. The default dead interval is restored when the network type for an interface is changed. Optional. The retransmission interval defaults to 5 seconds. Specifying LSA transmission delay Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change during transmission. It is necessary to add a transmission delay into the age time especially for low-speed links. To specify the LSA transmission delay on an interface: Step 1. Enter system view. 2. Enter interface view. 3. Specify the LSA transmission delay. Command system-view interface interface-type interface-number ospf trans-delay seconds Remarks N/A N/A Optional. 1 second by default. 79
