The output of "show ip ospf database" looks like this:
Link ID ADV Router Age Seq# Checksum Link count
172.18.0.61 172.18.0.61 347 0x80000290
0x0084A6 1
172.22.241.106 172.22.241.106 1174 0x80000063
0x007C52 1
172.22.241.107 172.22.241.107 785 0x80000130
0x00EB11 1
How is the "Age" to be interpreted?
Seconds or Minutes seem most likely, but the Cisco IOS IP command reference doesn't clearly specify the units of Link-state age.
