Re: [nv-l] Netview and OSPF

[Leslie Clark <lclark@us.ibm.com>]

I can confirm that you don't need to
do anything special for Netview to discover large and far-flung OSPF networks.
 Seed nodes are always helpful, however, regardless of the routing
protocol, especially for the impatient.

I think you are expecting way too much here, making it more complicated
than it is.   
I'm not the netmon expert, but I do know that auto discovery is a step-wise
process.  He discovers devices one step at a time, using the closest
first. 

My understanding is that NetView is reading your routing table only to
find the next hop.      He's only looking for a gateway
device that he can add to his database, and that he can then pull the arp
cache from to find new devices.  How the packets get routed to the
end device are not his concern. 
My belief is that he has no knowledge whatsoever of OSPF or any other router
protocol, because he doesn't need it.   

Someone will no doubt chime in if I am mistaken, but if the routing protocol
were important, then (a) it would appear as a filed in the database for
router objects, and (b) we would have a place for you to configure it,
probably in xnmsnmpconf.  Neither of those is the case.

Subject	[nv-l] Netview and OSPF

Question:   is there any type of information about how Netview deals
with the OSPF protocol?   I may be far gone in left field about this,
but if I understand the gist of things links in NV are determined mainly
by the routing tables of routers and the subnets.   How does NV deal
with Summary routes and multiple open routes between devices, and segments?

Any information would be helpful 

Thank you 
Chris Petrina
