[c-nsp] OSPF adj cycling FULL to LOADING?

[Ziti Bake]

I've been asked for more detail on the routers and
configs.  
Here are the relative bits of router config for each
end:

At location "A" (Sup720 swrouter):

> interface GigabitEthernet8/1
>  description Location A, Core LAN
>  ip address 10.0.1.200 255.255.255.0
>  ip ospf authentication-key kungpaosquid
>  load-interval 30
>
> interface GigabitEthernet8/16
>  description metro ethernet handoff, Location A
>  no ip address
>  mls qos vlan-based
>  switchport
>  switchport trunk encapsulation dot1q
>  switchport trunk allowed vlan 101-199
>  switchport mode trunk
>  switchport nonegotiate
>
> interface Vlan123
>  description Ethernet MAN to Location B
>  ip address 192.168.1.249 255.255.255.252
>
> router ospf 1
>  log-adjacency-changes
>  network 10.0.1.0 0.0.0.255 area 0.0.0.0

I added one command to enable OSPF over the MAN:
> ! NEW COMMAND:
>  network 192.168.1.248 0.0.0.3 area 0.0.0.0


At location "B" (Sup2 swrouter):

> interface GigabitEthernet2/1
>  description Ethernet MAN handoff, Location B
>  no ip address
>  mls qos vlan-based
>  switchport
>  switchport trunk encapsulation dot1q
>  switchport trunk allowed vlan 101-199
>  switchport mode trunk
>  switchport nonegotiate
>  no cdp enable
>
> interface GigabitEthernet1/1
>  description Location B, remoteLAN
>  ip address 192.168.1.2 255.255.255.0
>  ip route-cache flow
>  ip ospf authentication-key amazingcontraption
>  load-interval 30
>  no cdp enable
>
> interface Vlan123
>  description Ethernet MAN to Location A
>  ip address 192.168.1.250 255.255.255.252
>
> router ospf 1
>  log-adjacency-changes
>  area 10.0.0.0 authentication message-digest
>  network 192.168.1.0 0.0.0.255 area 10.0.0.0

I added the same new command to bring-up area 0 over
the MAN:
> ! NEW COMMAND:
>  network 192.168.1.248 0.0.0.3 area 0.0.0.0


There was no tweaking of timers, etc.

The only odd thing I can see, is that the router in
Location B was not connected to Area 0 before.  It was
only in area 10.  This MAN link  provides a second ABR
between area 10 and area 0.
