VMware Smart Assurance applications require unique instance name in their repositories. The conventional IP instance naming method, which is adding a prefix "IP-" to the IP address to create the name of the instance (for example, "IP-10.0.1.14"), is not applicable for overlapping IP addresses.
The Name of an overlapping IP instance will be in the following format:
IP-<IP address>/<route distinguisher>
The DisplayName attribute will be in the following format:
<route distinguisher>:<IP address> [host system name]
For example, router R1 has a VRF named “red.” Interface 15, which is associated with this VRF, has a duplicated IP address 10.0.1.14 and is part of the subnet 10.0.1.12/30. The route distinguisher of VRF “red” is “4445:401.” The name of this IP instance will be:
And its DisplayName will be:
In addition, the Tag attribute of the IP instance will have a value of “4445:401.”
