[c-nsp] Question on OSPF Routing Table

[Raymond Leung]

 Dear Gents / Madam :

I'm sorry that I may sent out twice on this issue.

I've a OSPF question and would like to know any idea from yours

Currently I've builded a network as follow :

We all are inside the area 0.0.0.3

RT1 < > RT2 < > RT3

RT3 annouce the 0.0.0.0/0 to RT2

Anything can make RT2's 0.0.0.0 route refresh suddenly as 23:57:42 ago
beside the OSPF or link down ?

RT2>sh ip route 0.0.0.0
Routing entry for 0.0.0.0/0, supernet
  Known via "ospf 141", distance 110, metric 3, candidate default path
  Tag 141, type extern 1
  Last update from 1.2.3.4 on FastEthernet2/1, 23:57:42 ago
  Routing Descriptor Blocks:
  * 5.6.7.8, from 6.7.8.9, 23:57:42 ago, via FastEthernet2/1
      Route metric is 3, traffic share count is 1

Thanks very much
Raymond
