BNG Redundancy for DHCP Subscribers on Juniper MX

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:

Deployment of vMX with Dual REs and Multiple FPCs using EVE-NG

Image
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...

Juniper EVPN-VXLAN Data Center Interconnection

Image
In this post, I will walk you through the deployment process of EVPN-VXLAN Data Center Interconnection. Data Centers are interconnected via WAN links and BGP has been enabled as both the Overlay and Underlay routing protocols. Each device within the IP fabric is assigned a unique Autonomous System Number (ASN) The underlay routing configuration ensures seamless reachability between all devices in the underlay the IP fabric. Overlay routing with VXLANs are reachable between VTEP across underlay IP fabric. EVPN-VXLAN configuration is established between DC1 and DC2 data centers, and Extended VLANs are configured to span between the two data centers, enhancing the scope and flexibility of the network. Here is the topology that I have designed and implemented: DC1-SW1 set interfaces ge-0/0/0 description TO-DC1-R1 set interfaces ge-0/0/0 unit 0 family inet address 192.168.253.2/30 set interfaces ge-0/0/1 description TO-DC1-SW2 set interfaces ge-0/0/1 unit 0 family inet ...
