The IP tagging feature, which was introduced in IP Manager 7.0, enables IP Availability Manager to discover and create IP objects for both VPN Routing and Forwarding (VRF) and non-VRF overlapping IP addresses, where a non-VRF overlapping IP address is defined as an overlapping IP address that is not part of an MPLS VPN.
Network Protocol Manager for BGP and Network Protocol Manager for OSPF are able to understand VRF and non-VRF IP objects that have been tagged by IP Availability Manager.
IP Availability Manager also creates a corresponding IPNetwork object and tags it with the same value that is used to tag the IP object. And, for both tagged IP and IPNetwork objects, IP Availability Manager sets the object’s Tag attribute to the tag value that is used to tag the object.
The Route Distinguisher (RD) IP tagging policy is used in versions 8.1.x and 9.x of the IP Manager. These features are described in the IP Manager documentation.
