Configuring Lsa Transmission Delay Time - 3Com MSR 50 Series Configuration Manual

Configuring LSA
Transmission Delay Time
LSA retransmit timer: Interval within which if the interface receives no
■
acknowledgement packets after sending a LSA to the neighbor, it will
retransmit the LSA.
Follow these steps to configure timers for OSPF packets:
To do...
Enter system view
Enter interface view
Specify the hello interval ospf timer hello seconds
Specify the poll interval
Specify the dead
interval
Specify the
retransmission interval
The hello and dead intervals restore to default values after you change the
■
network type for an interface.
The dead interval should be at least four times the hello interval on an
■
interface.
The poll interval is at least four times the hello interval.
■
The retransmission interval should not be so small for avoidance of unnecessary
■
LSA retransmissions. In general, this value is bigger than the round-trip time of
a packet between two adjacencies.
Since OSPF packets need time for traveling on links, extending LSA age time with
some delay time is necessary, especially for low speed links.
Follow these steps to configure the LSA transmission delay time on an interface:
To do...
Enter system view
Enter interface view
Set the LSA transmission delay

Optional
The hello interval on P2P, Broadcast
interfaces defaults to 10 seconds
and defaults to 30 seconds on
P2MP and NBMA interfaces.
Optional
The poll interval defaults to 120
seconds.
