Configuration template & loopback

[BenTen]

Hi everybody,

I'm writing a configuration template and i'm trying to fill automatically a Loopback parameter with SNMP request, using the OID of the loopback interface. I have to deploy this configuration template to a lot of devices, and the final OID destination (ip of the loopback) change for each. So i don't always collect the right ip address of the devices.

The loopback ip address i'm trying to collect is the one i use to join the devices.

Some one have an idea about how to do this ?

Thanks a lot.
