Networking
I could create a network by adding several interfaces to each VM and connect them to different vmnets to create a topology. This is quite inefficient however since creating a new logical topology would involve reconfiguration of the vmnets. It’s easier to connect one interface from each XRv to the same vmnet and rely on dot1q subinterfaces to create the logical topology.

My intention is to build and test the labs presented in MPLS in SDN Era Book:
As shown in the network diagram the BOM consist of:
Note: H/CE/BR devices can be built also using simple instance-type virtual routers as no additional inside virtualization is needed.
For different labs we might need to duplicate VMs: more IOS XR virtual routers, more vSRX Firewalls, etc.
Here is the procedure needed to multiply IOS XRv VMs. The same procedure can be used for any VM we need to safe or multiply.
The IOS XRv router is allready installed in my MacBook as detailed into my recent article Cisco IOS XRv on VMWare Fusion.
As I need a serial connection every time I want to change my LAB setup, I’ve defined my XRv serial connection into Secure CRT as described in the last section of my recent article SecureCRT to XRv Serial Console
I like to use SecureCRT to connect to my devices in all situations. But there are some exceptions when the things are not so straght forward. Continue reading
This article shows you what are the networks, the IP settings and the connections of the virtual elements.

In this article, I will show how I’ve installed my first IOS XRv router using print screens and step by step procedure. At the end, I’ve added also a problem I’ve encountered after installation. Let’s get started …

The Cisco IOS XRv Router is a Virtual Machine (VM) based platform running 32-bit IOS XR software with the QNX microkernel. This VM contains a single route processor (RP) with control plane functionality, and line card (LC) network interfaces with their associated functionality. It is a representation of the IOS XR software and operating system, including manageability, control plane features, routing and forwarding functionality. The Cisco IOS XRv Router is not an emulation of any physical router or hardware component.
