Chapter 3 OSPF Configuration Commands

Description
Using
ospf timer poll
command, you can configure the poll Hello packet interval on
NBMA and
p2mp
network. Using
undo ospf timer poll
command, you can restore the
default poll interval.
On the NBMA and
p2mp
network, if a neighbor is invalid, the Hello packet will be
transmitted regularly according to the
poll
seconds
. You can configure the
poll
seconds
to specify how often the interface transmits Hello packet before it establishes
adjacency with the adjacent router. Poll seconds should be no less than 3 times of
Hello.
Example
# Configure to transmit poll Hello packet from interface Vlan-interface 2 every 120
seconds.
[Quidway-Vlan-interface2] ospf timer poll 120
3.1.42 ospf timer retransmit
Syntax
ospf timer retransmit
interval
undo ospf timer retransmit
View
Interface view
Parameter
interval:
Interval in second for re-transmitting LSA on an interface. It ranges from 1 to
3600. The default value is 5 seconds.
Description
Using
ospf timer retransmit
command, you can configure the interval for LSA
re-transmitting on an interface. Using
undo ospf timer retransmit
command, you can
restore the default interval value for LSA re-transmitting on the interface.
If a router running OSPF transmits a "link state advertisement" (LSA) to the peer, it
needs to wait for the acknowledgement packet from the peer. If no acknowledgement is
received from the peer within the LSA retransmit, this LSA will be re-transmitted. This
command can change the interval of re-transmitting LSA. However, according to
RFC2328, the LSA retransmit between adjacent routers should not be set too short.
Otherwise, unexpected re-transmission will be caused.
