Specifying Lsa Transmission Delay - HP MSR Series Configuration Manual

Poll timer—Interval for sending hello packets to a neighbor that is down on the NBMA network. The
•
poll interval is at least four times the hello interval.
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 a 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.
3. Specify the hello
interval.
4. Specify the poll
interval.
5. Specify the dead
interval.
6. Specify the
retransmission
interval.

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. Therefore, 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.

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.
