User-defined IP tagging occurs when you create an IP tag filter group in IP Availability Manager or IP Performance Manager based on specific deployment and specifies a tag value and an overlapping IP address range for the group. The user-specified tag may be applied to both non-VRF overlapping IP addresses and VRF IP addresses, where a non-VRF overlapping IP address is defined as an overlapping IP address that is not part of an MPLS Layer 3 VPN. In addition, users can configure an IP tag filter group to double-tag the name of the objects created for discovered VRF IP addresses, or to replace the route distinguisher tag in the name of these objects with the user-specified tag.
For every IP address that falls within the overlapping IP address range of an IP tag filter group, the IP Manager creates an IP object and tags its name with the user-specified value. 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.)
