Hi Mates,

Bit confussed for some of the routes get the timer period changed . show ip ospf output provided below:

Routing entry for 10.107.0.0/16

  Known via "ospf 300", distance 110, metric 1, type extern 2, forward metric 1

  Last update from 10.120.105.34 on GigabitEthernet1/0/11, 1d00h ago

  Routing Descriptor Blocks:

  * 10.120.106.230, from 10.130.240.62, 1d00h ago, via GigabitEthernet1/0/12

      Route metric is 1, traffic share count is 1

    10.120.105.34, from 10.130.240.62, 1d00h ago, via GigabitEthernet1/0/11

      Route metric is 1, traffic share count is 1

**************************

WANEDGE-#sh ip route 10.136.118.0  ……………….

Routing entry for 10.136.118.0/24

  Known via "ospf 300", distance 110, metric 1

  Tag 65527, type extern 2, forward metric 1

  Last update from 10.120.105.34 on GigabitEthernet1/0/11, 1d00h ago

  Routing Descriptor Blocks:

  * 10.120.106.230, from 10.130.240.62, 1d00h ago, via GigabitEthernet1/0/12

      Route metric is 1, traffic share count is 1

      Route tag 65527

    10.120.105.34, from 10.130.240.62, 1d00h ago, via GigabitEthernet1/0/11

      Route metric is 1, traffic share count is 1

      Route tag 65527

Does it mean that the Ospf routes has been got flushed for the mention destinaion network. Need a small help for my understanding and what may be reason to get those timer value reset again.

Ospf routes timer get reset

The route time that you're seeing is how long the route has been valid in the table. If it's dropping from say, 20 days to 1 day, then the route is dropping out of the table somehow. You can go to the router in question and do a 'show ip ospf neighbor

' to see how long the neighbors have been up to verify which neighbor it's having a problem with.

Neighbor 10.124.0.12, interface address 10.124.0.12

    In the area 4 via interface FastEthernet0/1

    Neighbor priority is 1, State is FULL, 6 state changes

    DR is 10.124.0.4 BDR is 10.124.0.12

    Options is 0x52

    LLS Options is 0x1 (LR)

    Dead timer due in 00:00:36

    Neighbor is up for 23:40:49

    Index 1/2, retransmission queue length 0, number of retransmission 4

    First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)

    Last retransmission scan length is 1, maximum is 1

    Last retransmission scan time is 0 msec, maximum is 4 msec
