Configuring VRF-Aware Device Interfaces

To give NetMRI access to the routed domain for a mapped VRF, the user must connect NetMRI to one of the interfaces, on the VRF-aware device, that belongs to that virtual network. The user needs to provide visibility on their virtual network to the scan interface that is discovering it.

• If the VRF-aware device is directly connected to NetMRI: If the mapped NetMRI scan interface is a physical SCAN interface, the user must use or configure a physical interface on the target VRF-aware device to communicate with NetMRI without using 802.1Q encapsulation.

If the mapped scan interface is a logical sub-interface using 802.1Q encapsulation, the user configures the directly connected physical interface of the VRF-aware device and subdivides it using a logical subinterface with the same 802.1Q encapsulation. The user may otherwise use a VLAN interface with the same 802.1Q encapsulation and allow its traffic through the physical SCAN interface.

• If the VRF-aware device is not directly connected to NetMRI: No additional configuration is required for these devices. NetMRI can reach different VRFs from the moment these resources are routed by a VRF mapped into a Network View which is accessible from a scan interface mapped on that same Network View.

You may apply different techniques, such as using VLANs all the way down to the desired VRF to discover, or using intermediate devices that are members of the routed domain of that VRF.
