The JunosInsights: Exploring Networking with Juniper

In this post, I will guide you through the process of deploying vMX with dual REs and multiple FPCs using EVE-NG. To begin, you will need to download the vMX KVM bundle from the Juniper website. For this lab, we will be using Junos 21.4. Extract the vMX bundle: mkdir /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re0 mkdir /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re1 mkdir /opt/unetlab/addons/qemu/vmxvfp-21.4R3-S1.5-fpc0 mkdir /opt/unetlab/addons/qemu/vmxvfp-21.4R3-S1.5-fpc1 Copy the images to their respective directories: ## RE0 cp /root/vmx/images/junos-vmx-x86-64-21.4R3-S1.5.qcow2 /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re0/virtioa.qcow2 cp /root/vmx/images/vmxhdd.img /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re0/virtiob.qcow2 cp /root/vmx/images/metadata-usb-re0.img /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re0/virtioc.qcow2 ## RE1 cp /root/vmx/images/junos-vmx-x86-64-21.4R3-S1.5.qcow2 /opt/unetlab/addons/qemu/vmxvcp-21.4R3-S1.5-re1/virtioa.qcow2 cp /r...

Recently, I encountered a challenge while assisting a customer who sought a solution for deploying a redundant DHCP service to accommodate DHCP subscribers on two MX routers. Unfortunately, Juniper website currently lacks resources or examples specifically addressing the deployment of a redundant DHCP service for DHCP subscribers. Therefore, I took the initiative to set up a lab environment comprising two vMX routers functioning as BNG routers (BNG-1 and BNG-2), along with an additional MX router operating as the DHCP server. Here is the topology that I have designed and implemented:   BNG-1 set system host-name BNG-1 set system services subscriber-management enable set system services subscriber-management redundancy interface xe-0/0/3.1492 virtual-inet-address 172.16.0.129 set system services subscriber-management redundancy interface xe-0/0/4.1493 virtual-inet-address 172.16.0.1 set system services subscriber-management redundancy protocol vrrp set system servic...
