hello,

i'm not sure what to think now :( i have done the following.

set ospf enable
save all
reboot

add area 30
set ospf area 30 range 204.71.56.0/24
save all
reboot

(save all, reboot, ad nauseam :)

here is output of a few applicable commands

pm-ftc-b> sh tab ospf
Stub
Authentication Area Default
Area Network Range Type ID Key Type Cost
--------------- ------------------ ---- --- ---------------- -------- -------
0.0.0.30 *204.71.56.0/24 None Stub 1

pm-ftc-b> sh ospf nei
Inter- Last MD5
face Area Neighbor State Pri IP Address Hello ID
------ --------------- --------------- -------- --- --------------- ----- ---
ether0 0.0.0.30 208.146.241.37 Full/DR 1 204.71.56.254 1 N/A

pm-ftc-b> sh rout
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------
0.0.0.0 0 204.71.56.254 local NS 1 ether0
208.146.243.20 32 208.146.243.20 local HL 1 ptp1

here, the 208.146.243.20/32 address is the one in question. it is not
getting advertised by the portmaster.

what are we missing?
