What exactly are ou trying to do? I'll guess.
Guess 1: You want to do things with these smart sets (like threshold
snmp data), and you want NetView to use the loopback interfaces to query
the router (since it will always be a reachable destination should at
least one interface be reachable). It that's true, you can't get
there by doing this. You can create a collection of lopopback
interfaces, but they are not nodes from which you can collect data.
The solution is to control the discovery process so that NetView uses
the correct interface (loopback) to talk SNMP to the router. To do
1. Make sure that the loopback interfaces resolve to the router name,
and that this name resolves to the loopback address. This forward
and reverse resolution is critical for NetView to function
correctly. If the name doesn't resolve to an address that resolves
back to the name, you'll have problems.
2. Create a seedfile with the loopback IP addresses.
3. Delete all 600 routers and re-read the seedfile. (I know this is
drastic - but take heart - you'll never have to do it again).
Guess 2: You just want to create a collection of Cisco Routers. Look
at the fields of the routers and see if you can find something common:
Look at the vendor field. Do you have a field called isCisco? So maybe
your rule could be: "(('vendor' = 'Cisco') && ('isRouter'='TRUE'))"
or "((isCisco= TRUE) && (isRouter=TRUE))".
