H3C S7500 Series Ethernet Switches Chapter 3 OSPF Configuration Commands
3-44
Description
Use the ospf timer poll command to configure the poll interval on an NBMA and p2mp
interface.
Use the undo ospf timer poll command to restore the default value.
When an NBMA or P2MP interface finds its neighbor is dead, it will send hello packets
at the poll interval. The poll interval is at least three times the hello interval.
Examples
# Set the poll timer interval on interface VLAN-interface 20 to 120 seconds.

[H3C] interface Vlan-interface 20
[H3C-Vlan-interface20] ospf timer poll 120
3.1.40 ospf timer retransmit
Syntax
ospf timer retransmit interval
undo ospf timer retransmit
View
Interface view
Parameters
interval: LSA retransmit timer interval in seconds, in the range 1 to 3600. The default is
5.
Description
Use the ospf timer retransmit command to set the LSA retransmit interval on an
interface.
Use the undo ospf timer retransmit command to restore the default.
After sending a LSA, an interface waits for an acknowledgement packet. If the interface
receives no acknowledgement when the retransmit interval elapses, it will retransmit
the LSA.
The retransmit interval should not be too small to avoid unnecessary retransmissions
(See RFC 2328).
Examples
# Set the LSA retransmit interval on the interface VLAN-interface 10 to 12 seconds.
