vRouter - Manage vRouter
Manager → Layer 3 → vRouter
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.
vRouters are virtual constructs that handle all Layer-3 traffic in NetVisor OS switches and fabrics.
NetVisor UNUM automatically configures vRouters based on the type of playbook chosen when a fabric is built.
In Layer-2 Fabrics, vRouters are created on the spines and the Virtual Router Redundancy Protocol (VRRP) is configured between the spines.
In Layer-3 Fabrics, vRouters are created on the leafs and the Virtual Router Redundancy Protocol (VRRP) is configured between the leafs.
In most white-box switching environments, one vRouter will be configured per switch. There are exceptions for this in large environments, or where powerful switches with extra resources are available.
A Virtual Router (vRouter) is an integral part of fabric functionality. For example, for a VLAN to communicate with other VLANs, or networks external to the fabric, it may need a vRouter that spans the internal and the external network.
Fabric-wide vRouter commands can only be executed at the fabric level by the fabric administrator.
Note: For switches with NetVisor OS, the only available vNET is a global vNET created when creating a fabric for the first time. However, some switches support multiple vNETs based on the platforms. Please refer to the Release Notes for the supported platforms.
Routing protocols essentially work the same way on virtual routers as physical routers.
Note: In the event you need to create a new vRouter, chose the “Hardware” option.
Create a vRouter Example
Example: A vrouter is connected to another vrouter which is mapped to Physical router with port number 48 along with two virtual interfaces for VLAN 10 and VLAN 20
Layer 3 Configuration - vRouter
Manage vRouters
Selecting Manager → Layer 3 → Manage vRouters displays the Manage vRouters dashboard with a list of any existing vRouter settings.
Select the applicable Fabric from the left-hand navigation bar and the dashboard updates showing all vRouter 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.
This feature table displays data based on the fabric's default Collector Switch. If no data displays in the dashboard, either select a switch from the Left-hand Navigation (LHN) pane or perform a Search by selecting an FRG (Fabric Resource Group) and a specific Attribute from the drop-down lists, as required.
The dashboard displays a list of existing vRouter entries by Fabric.
The Advanced Search function provides a rapid method to search across Fabrics, Fabric Resource Groups and feature Attributes.
Additional parameters include: Switch, Name, Type, Scope,Vnet, State, Router-Type, HW MAC, A-A Routing, HW VR. ID, HW VRRP ID, BGP-AS, Router ID, and EVPN Border.
The vRouter information is scope dependent meaning either Fabric or Local.
Manager vRouter Fabric Dashboard
Select the applicable switch from the fabric and the dashboard updates automatically with vRouter settings.
Manager vRouter Switch Dashboard
Select the applicable switch from the fabric. The dashboard displays a list of existing vRouter entries by Name.
Additional parameters include: Type, Scope,Vnet, State, Router-Type, HW MAC, A-A Routing, HW VR. ID, HW VRRP ID, BGP-AS, Router ID, and EVPN Border.
Create vRouters
Hardware and software vRouters are created by selecting either Create H/W vRouter or Create H/W vRouter for Fabric Communication.
