(PM) OSPF confusion

I'm a little confused about one small issue with OSPF. We were recently
assigned two new class C's by our upstream provider, and this was my first
chance to implement OSPF. Everything seems to be working properly--i.e. I
haven't received any calls from people complaining about service problems,
but I'm confused as to why our Cisco 4000's route table shows routes learned
from our PM3 as external type 2s, instead of internal LSAs. Here are the
commands I used to configure OSPF on both boxes:

Assume 2 C classes, 192.168.10.0 and 192.168.20.0.

Cisco 4000: (ethernet interface is network 192.168.10.1, on network
192.168.10.0/24)

conf t
router ospf 100
network 192.168.10.0 0.0.0.255 area 0
^Z
write mem
conf t
int e0
ip ospf priority 50
ip ospf hello-interval 10
ip ospf dead-interval 40
ip ospf authentication-key blah
^Z
write mem
conf t
router ospf 100
area 0 authentication

PM3: (first assigned address 192.168.20.16, pool size 48, ether0 address is
192.168.10.8)
set ospf enable
save all
reboot
set ospf priority 0
add ospf area 0
set ospf area 0 range 192.168.10.0/24 range 192.168.20.16/28 range
192.168.20.32/27
set ether0 ospf on
save all
reboot

Now, on the Cisco, a "sh ip route" shows the PM3's announced routes as:
192.168.20.0/24 is variably subnetted, 2 subnets, 2 masks
O E2 192.168.20.16/28 [110/2] via 192.168.10.8, 21:19:45, Ethernet0
O E2 192.168.20.32/27 [110/2] via 192.168.10.8, 21:19:45, Ethernet0

Shouldn't these be announced as type "O IA", or am I really screwing it up?
At any rate, it all works, so I really don't have a problem. I just want to
make sure that I don't have a problem waiting to bite me down the road.
