Karl,
It's all perspective.
From the 192.168.1 subnet perspective, the node is OK - working just fine on this subnet
Form the 10.253 subnet perspective, the node is Critical - Dead on this subnet
From the Internet perspective, the "router" is marginal.

Hi,
 
Maybe I'm loosing it/too late, but I'm seeing something simple/weird I can't explain....
Using RedHat 7.2, nv 7.1.3 fp1
 
I've got a node (w2k) with two interfaces (one real 192.168.1 and one a loopback adapter 10.253 with static ipaddr). 
The status propagation doesn't seem right to me;
 
Internet (yellow)
->192.168.1 (green)
-->> Segment1 (green)
--->>> MyNode (green)
---->>>> 10.253.1.50 (red)
---->>>> 192.168.1.10 (green)
->10.253 (red)
-->> Segment1 (red)
--->>> MyNode (red)
---->>>> 10.253.1.50 (red)
---->>>> 192.168.1.10 (green)
 
 
The map is the default and is set (unchanged) to default propogation.
 
The status of MyNode seems wrong under both networks - shouldn't it show marginal since only one interface is down?
The status of the two networks also seems wrong - shouldn't they both be marginal too - they would be cascading the severity up?
The root Internet seems right - at least one contained object is down so it is marginal.
 
Anyone got any views - I've just been doing this with multiple nested submaps on AIX and I know it worked ok - I've got screenshot to prove it (that being the only way to stave off madness I reckon...).  I'm sure I didn't change any status propogation there....
 
Thanks in advance
 
 
Karl
