    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.

    OSPF RFC is the reference to be checked and it indicates that LS age
    is in seconds
