Arista NetVisor UNUM 6.3.2

Layer 3 Configuration - Manage VRF Route

Fabric VRFs are lightweight distributed atomic constructs created without the need for a local vRouter, and they do not currently support any routing protocols on VRF instances. This choice enables very high scalability and very low overhead in managing the distributed segmentation and routing function.

You can connect fabric VRFs to third party VRF routers or gateways either directly using static routing or through a redundant group of border leaf switch(es) running the vRouter function mapping 1:1 to the Fabric VRF instances. In the latter case, border leaf switches can run any supported IGP protocol to interconnect with third-party VRF routers or gateways.

Use Static routing to install more than two routes or change the VRF exit point for specific destination prefixes.

There are features and functions used in Arista NetVisor UNUM and Insight Analytics that are common throughout the user interface (UI). Please refer to the Common Functions section for more information on the use of these functions and features.

Selecting Manager → Layer 3 → Manage VRF Route displays the Manage VRF Route dashboard with a list of any existing VRF Route settings. 

Note: This feature is supported only on Dell, Edgecore, and Freedom series switches.

Select the applicable Fabric from the left-hand navigation bar and the dashboard updates showing all VRF Route entries from all switches within the Fabric.

Note: If no entries exist a "No Data Exists" message is displayed. You must first configure an entry on a switch. Prerequisite settings and configuration may be required.

The dashboard displays a list of existing VRF Routes entries by Switch. Additional parameters include: Switch, vrfs, Network, Netmask, Gateway-ip, Scope, and Active.
