OSPF area 10.0.1.1
configured as stub area
It doesn't matter if I set stub-default-cost to something or not.

One person was logged in at this point in time, he was using one of
the dynamically assigned addresses out of this PM3's assigned pool
(meaning: no extra routing table entries generated outside of
the PM3).
On the Linux 2.2.5 gated 3.11-Alexey I have in gated.conf:
routerid 1.2.3.27;
ospf yes {
defaults {
router-prio;
};
backbone {
interface 10.0.0.27 {
enable;
priority 2;
auth simple "hi";
};
};
area 10.0.1.1 {
stub cost 1;
interface 10.0.1.6 {
auth simple "ho";
};
};
area 10.0.1.9 {
stub cost 1;
interface 10.0.1.14 {
auth simple "ha";
};
};
}
static {
default gateway 194.183.100.65;
};
export proto ospfase type 1 {
proto rip;
proto ospf;
proto ospfase;
proto direct;
proto kernel;
};
export proto ospfase type 2 {
proto static {
default metric 1;
};
};
Now, if we check the routing table on the PM3, we see that
it does *not* adopt the default route which my gated is
advertising (or at least, seems to be):
> sh route
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------
111.22.3.178 32 111.22.3.178 local HL 1 ptp0
10.0.1.8 29 10.0.1.6 ospf/IA ND 2 ether0
10.0.1.0 29 10.0.1.1 local NL 1 ether0
10.0.0.0 27 10.0.1.6 ospf/IA ND 2 ether0
The topology here roughly is:
PM3 10.0.1.1 ---------------- 10.0.1.6 Linux gated 10.0.0.27 ----\
10.0.1.0/29 10.0.1.14 |
| |
| Rest of the world
10.0.1.8/29 /
__________________/
Whereas the routerid of the 10.0.1.1 PM3 is equal to 10.0.0.13
and the routerid of the Linux gated box is 1.2.3.27
I've tried different stub cost settings (higher in the PM3,
higher in gated), nothing seems to convince the PM3 to create a
default route to the Linux gated box.
Any insight would be appreciated.
