This -design is based on a VM as the primary router and a physical machine as a -backup, using VRRP, BGP, OSPF, and conntrack sharing. - -This document aims to walk you through setting everything up, so -at a point where you can reboot any machine and not lose more than a few -seconds worth of connectivity. - -## Design - -This is based on a real-life production design. One of the complex issues -is ensuring you have redundant data INTO your network. We do this with a pair -of Cisco Nexus switches and using Virtual PortChannels that are spanned across -them. As a bonus, this also allows for complete switch failure without -an outage. How you achieve this yourself is left as an exercise to the reader. -But our setup is documented here. - -### Walkthrough suggestion - -The `commit` command is implied after every section. If you make an error, -`commit` will warn you and you can fix it before getting too far into things. -Please ensure you commit early and commit often. - -If you are following through this document, it is strongly suggested you -complete the entire document, ONLY doing the virtual router1 steps, and then -come back and walk through it AGAIN on the backup hardware router. - -This ensures you don't go too fast or miss a step. However, it will make your -life easier to configure the fixed IP address and default route now on the -hardware router. - -### Example Network - -In this document, we have been allocated 203.0.113.0/24 by our upstream -provider, which we are publishing on VLAN100. - -They want us to establish a BGP session to their routers on 192.0.2.11 and -192.0.2.12 from our routers 192.0.2.21 and 192.0.2.22. They are AS 65550 and -we are AS 65551. - -Our routers are going to have a floating IP address of 203.0.113.1, and use -.2 and .3 as their fixed IPs. - -We are going to use 10.200.201.0/24 for an 'internal' network on VLAN201. - -When traffic is originated from the 10.200.201.0/24 network, it will be -masqueraded to 203.0.113.1 - -For connection between sites, we are running a WireGuard link to two REMOTE -routers and using OSPF over those links to distribute routes. That remote -site is expected to send traffic from anything in 10.201.0.0/16 - -### VLANs - -These are the vlans we will be using: - -- 50: Upstream, using the 192.0.2.0/24 network allocated by them. -- 100: 'Public' network, using our 203.0.113.0/24 network. -- 201: 'Internal' network, using 10.200.201.0/24 - -### Hardware - -- switch1 (Nexus 10gb Switch) -- switch2 (Nexus 10gb Switch) -- compute1 (VMware ESXi 6.5) -- compute2 (VMware ESXi 6.5) -- compute3 (VMware ESXi 6.5) -- router2 (Random 1RU machine with 4 NICs) - -Note that router1 is a VM that runs on one of the compute nodes. - -### Network Cabling - -- From Datacenter - This connects into port 1 on both switches, and is tagged - as VLAN 50 -- Cisco VPC Crossconnect - Ports 39 and 40 bonded between each switch -- Hardware Router - Port 8 of each switch -- compute1 - Port 9 of each switch -- compute2 - Port 10 of each switch -- compute3 - Port 11 of each switch - -This is ignoring the extra Out-of-band management networking, which should be -on totally different switches, and a different feed into the rack, and is out -of scope of this. - -:::{note} -Our implementation uses VMware's Distributed Port Groups, which allows -VMware to use LACP. This is a part of the ENTERPRISE licence, and is not -available on a free licence. If you are implementing this and do not have -access to DPGs, you should not use VMware, and use some other virtualization -platform instead. -::: - -## Basic Setup (via console) - -Create your router1 VM. So it can withstand a VM Host failing or a -network link failing. Using VMware, this is achieved by enabling vSphere DRS, -vSphere Availability, and creating a Distributed Port Group that uses LACP. - -Many other Hypervisors do this, and I'm hoping that this document will be -expanded to document how to do this for others. - -Create an 'All VLANs' network group, that passes all trunked traffic through -to the VM. Attach this network group to router1 as eth0. - -:::{note} -VMware: You must DISABLE SECURITY on this Port group. Make sure that -`Promiscuous Mode`, `MAC address changes` and `Forged transmits` are -enabled. All of these will be done as part of failover. -::: - -### Bonding on Hardware Router - -Create a LACP bond on the hardware router.

Is recommended to -take special consideration while designing route-targets and its application as -it can minimize future interventions while creating a new VRF will automatically -take the desired

-IP/MPLS technology is widely used by various service providers and large -enterprises in order to achieve better network scalability, manageability -and flexibility. It also provides the possibility to deliver different -services for the customers in a seamless manner. -Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered -through OSI layer 3 networking technologies. Often the border gateway -protocol (BGP) is used to send and receive VPN-related data that is -responsible for the control plane. L3VPN utilizes virtual routing and -forwarding (VRF) techniques to receive and deliver user data as well as -separate data planes of the end-users. It is built using a combination of -IP- and MPLS-based information. Generally, L3VPNs are used to send data -on back-end VPN infrastructures, such as for VPN connections between data -centres, HQs and branches. - -An L3VPN consists of multiple access links, multiple VPN routing and -forwarding (VRF) tables, and multiple MPLS paths or multiple P2MP LSPs. -An L3VPN can be configured to connect two or more customer sites. -In hub-and-spoke MPLS L3VPN environments, the spoke routers need to have -unique Route Distinguishers (RDs). In order to use the hub site as a -transit point for connectivity in such an environment, the spoke sites -export their routes to the hub. Spokes can talk to hubs, but never have -direct paths to other spokes. All traffic between spokes is controlled -and delivered over the hub site. - -To deploy a Layer3 VPN with MPLS on VyOS, we should meet a couple -requirements in order to properly implement the solution. -We'll use the following nodes in our LAB environment: - -- 2 x Route reflectors (VyOS-RRx) -- 4 x Provider routers (VyOS-Px) -- 3 x Provider Edge (VyOs-PEx) -- 3 x Customer Edge (VyOS-CEx) - -The following software was used in the creation of this document: - -- Operating system: VyOS -- Version: 1.4-rolling-202110310317 -- Image name: vyos-1.4-rolling-202110310317-amd64.iso - -**NOTE:** VyOS Router (tested with VyOS 1.4-rolling-202110310317) -– The configurations below are specifically for VyOS 1.4.x. - -General information can be found in the -{ref}`configuration/vrf/index:L3VPN VRFs` chapter. - -## Topology - -```{image} /_static/images/L3VPN_hub_and_spoke.webp -:align: center -:alt: Network Topology Diagram -:width: 80% -``` - -## How does it work? - -As we know the main assumption of L3VPN “Hub and Spoke” is, that the -traffic between spokes have to pass via hub, in our scenario VyOS-PE2 -is the Hub PE -and the VyOS-CE1-HUB is the central customer office device that is responsible -for controlling access between all spokes and announcing its network prefixes -(10.0.0.100/32). VyOS-PE2 has the main VRF (its name is BLUE_HUB), its -own Route-Distinguisher(RD) and route-target import/export lists. -Multiprotocol-BGP(MP-BGP) delivers L3VPN related control-plane information to -the nodes across network where PEs Spokes import the route-target 60535:1030 -(this is export route-target of vrf BLUE_HUB) and export its own route-target -60535:1011(this is vrf BLUE_SPOKE export route-target). Therefore, the -Customer edge nodes can only learn the network prefixes of the HUB site -[10.0.0.100/32]. For this example VyOS-CE1 has network prefixes -[10.0.0.80/32] / VyOS-CE2 has network prefixes [10.0.0.90/32]. -Route-Reflector devices VyOS-RR1 and VyOS-RR2 are used to simplify network -routes exchange and minimize iBGP peerings between devices. -

I do this by adding two rules -to every ruleset. 1 allows established and related state packets through -and rule 2 drops and logs invalid state packets. We place the -established/related rule at the top because the vast majority of traffic -on a network is established and the invalid rule to prevent invalid -state packets from mistakenly being matched against other rules.
