Parameter
seconds Enter the the poll Hello interval in seconds, in the range 1 to 65535. The
default value is 120 seconds.
Description
Using the ospf timer poll command, you can configure the poll Hello packet
interval.
Using the undo ospf timer poll command, you can restore the default poll
interval.
The Poll interval should be at least three times the Hello interval.
Example
To set the transmit poll Hello packet interval to 130 seconds for interface
Vlan-interface 2, enter the following:

Parameter
interval Enter the interval allowed before LSA re-transmission. This time is set for
an interface, in seconds, in the range 1 to 65535. The default value is 5 seconds.
Description
Using the ospf timer retransmit command, you can configure the interval
before LSA re-transmission on an interface.
Using the undo ospf timer retransmit command, you can restore the default
interval value for LSA re-transmission on an interface.
When a router transmits a Link State Advertisement (LSA) to the peer, it waits for
the acknowledgement packet. If no acknowledgement is received from the
neighbor within the time you set using this command, the LSA is re-transmitted.
According to RFC2328, the LSA retransmit between adjacent routers should not
be set too short. Otherwise, unexpected re-transmission will be caused.
Example
To set the retransmit interval between the interface Vlan-interface 1 and the
adjacent routers to 12 seconds, enter the following:
[SW7700]interface Vlan-interface 1
[SW7700-Vlan-interface1]ospf timer retransmit 12
