Hello List.

I'm using a 7201 as a LNS (pppoa), whenever a connection drops or a
new one comes online all ospf routes have their lifetime reset to 0.

cisco-7201>show ip route ospf

O E2
[110/20] via, 00:01:48, GigabitEthernet0/0
[110/20] via, 00:01:48, GigabitEthernet0/1

router ospf 1
 redistribute connected subnets
 redistribute static subnets
 passive-interface default
 no passive-interface GigabitEthernet0/0
 no passive-interface GigabitEthernet0/1
 network area 0
 default-information originate always
 distribute-list 50 in

External flood list length 0
    Area BACKBONE(0)
        Number of interfaces in this area is 729 (4 loopback)
        Area has no authentication
        SPF algorithm last executed 00:00:04.940 ago
        SPF algorithm executed 33927 times
        Area ranges are
        Number of LSA 9. Checksum Sum 0x051A57
        Number of opaque link LSA 0. Checksum Sum 0x000000
        Number of DCbitless LSA 0
        Number of indication LSA 0
        Number of DoNotAge LSA 0
        Flood list length 0

I'm running the same config on a 7206 without any issue's

cisco-7206>show ip route ospf

O E2
[110/20] via, 1d11h, GigabitEthernet0/3.999
[110/20] via, 1d11h, GigabitEthernet0/1.999

Thanks for your time.
