Description
Use the
ospf timer poll
command to configure the poll interval at which the interface sends hello
packets to the neighbor in the Down state.
Use the
undo ospf timer poll
command to restore the default.
By default, the poll interval is 40 seconds.
On an NBMA network, if a neighbor becomes invalid, Hello packets will be transmitted at intervals of
poll
seconds
. You can configure the
poll
seconds
to specify how often the interface transmits Hello
packets before it establishes neighbor relationship with the router. The poll interval should be no less
than 4 times the Hello interval.
Examples
# Configure to transmit poll Hello packet through interface VLAN-interface 20 every 130 seconds.

Parameters
interval:
Interval, in seconds, for retransmitting LSA on an interface. It ranges from 1 to 3600.
Description
Use the
ospf timer retransmit
command to configure the interval for retransmitting an LSA on an
interface.
Use the
undo ospf timer retransmit
command to restore the default.
By default, the interval for retransmitting an LSA is 5 seconds.
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 retransmission interval, this LSA will be retransmitted.
The LSA retransmit between adjacent routers should not be set too short; otherwise, unexpected
retransmission will occur (See RFC2328).
Examples
# Set the interval for retransmitting LSA between the interface VLAN-interface 10 and the adjacent
routers to 12 seconds.
