Automatic IP tagging works as enumerated below:

  1. For every MPLS-related VRF IP address collected for a discovered system, the IP Manager creates an IP object and tags its name with the route distinguisher (RD) tag value that is associated with the VRF to which the VRF IP address belongs. The IP Manager obtains the RD tag by reading the vendor VPN MIB on the discovered system.

  2. The IP Manager tags the name of the IP object with a route distinguisher value regardless of whether the VRF IP is — or is not — an overlapping IP address.

    The IP Manager also creates a corresponding IPNetwork object and tags it with the same value that is used to tag the IP objects. The IP objects have a ConnectedVia relationship with the IPNetwork object.


    Automatic IP tagging is also known as VRF IP tagging.
