The Summaries tab (Network Explorer > Summaries) lists routes, subnets, VLANs, Route Targets, HSRPs/VRRP groups, ports, NIOS grids, network views, and VRFs (virtual routing and forwarding instances) in the network.
- To list inventoried items, click the desired category in the left panel.
- To restrict the center panel table to a specific device group, click the group name in the Select Device Groups panel (on the right side of the window).
- To view details about any item in the left panel, click the row for that item. Details appear in the center panel.

The Routes section lists routes reported by all devices in the network, from each of their interfaces, during the last network polling cycle by NetMRI. It displays only Best Origin routes from the network. That is, NetMRI filters all collected routes to find a route with a minimal Administrative Distance for each CIDR and displays only this one.

Click the View All Routes link to list all routes in the center panel. Then apply a filter, such as an IP address, to isolate them for a device. This effectively allows you to view the routing table for a device in NetMRI. |
Routes are listed by the protocol (proto), the route's IP, the VRF Name containing the interface, its VRF route distinguisher, and the Count. The count is the number of devices reporting that particular route during the last polling period. All IPv4 and IPv6 routes are listed for all router and switch-router devices.
- To list devices comprising the route, click a route in the left panel. The center panel refreshes to show the device reporting the route, the route's interface from which it was reported, the Network View for the management IP of the device reporting the route, and the route's Next Hop. The list also shows each device's Route Distinguisher. This feature can be helpful in tracing a path.
- To view detailed data for a device, click the IP address hyperlink in the center panel. The Device Viewer opens.
The Subnets section lists subnets found in the network, the Network View for the management IP of the device reporting the subnets, and its VRF Name (if any). The list of subnets is compiled from all router and switch-router devices discovered and cataloged by NetMRI, including any virtual device contexts (VDC).
- For subnets, the Count is the number of devices discovered as part of the subnet during the last polling period.
- To list all devices in the subnet, click a subnet in the left panel.
- To view detailed data for any device in a subnet, click the IP address hyperlink in the right panel. The Device Viewer opens, listing any current Issues associated with the selected device.
The Device Viewer is not limited to this information. Seven categories of detailed information are provided by the Device Viewer for the displayed network entity. For more information, see Inspecting Devices in the Network.

After virtual routing and forwarding (VRF) networks are discovered and mapped to network views, you can use the VRFs summary to view the complete list of VRF instances throughout the managed network. You can sort the VRF information by any data column to see the relationships between VRF instances in virtual networks.
To view the complete list of VRF instances, click the View all VRFs link at the top of the list. By default, the VRFs are listed by VRF name. Data columns include the following:
- VRF Name: Displays the name of the VRF instance.
- VRF Description: Displays a description if the VRF instance is configured with a description on the device.
- Route Distinguisher: VRFs use route distinguishers to distinguish one set of routes (one VRF) from another. The route distinguisher is a unique number pre-pended to each route within a VRF to identify it as belonging to that particular VRF. The discovered route distinguisher value is listed here if a virtual network instance uses this value. For more information, see Summarizing Route Targets.
- Device Name: The discovered name of the device hosting the VRF instance.
- IP Address: The IP address of the managed VRF-hosting device. This value is a hotlink to the Device Viewer.
- Network View: The network view of the managed VRF-hosting device. This value is a hotlink to the Network Viewer window.
- VRF Network View: The network view to which the VRF is assigned. This value is a hotlink to the Network Viewer window. Note that this value may differ from the Network View identifier.
