We integrated ITNM with TBSM using a policy and the XMLToolkit. The requirement was to represent the MPLS VPNs in a service tree and show the VPN Type, VPN Name, devices used in the VPN and the interfaces on the devices. ITNM does not represent the data this and default import using the DLA didn't give us what we wanted or needed.
We started scouring the ITNM Oracle database and found the entityID's for the devices and worked from there to find the devices, interfaces and vpn names and types and then built the service tree hierarchy based on the SQL query. This process created book that the XMLtoolkit read (API data).
We can provide innovative solutions for you, too. Contact Tony Delgross at tony@gulfsoft.com to get the ball rolling.
