-This document walks you through a complete HA setup of two VyOS machines. 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. - -The aim of this document is to walk you through setting everything up so you -and up 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, in 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. This as an added bonus, 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 to 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 AS65551. - -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 wll 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 is able to 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.

This is an IPv6 alternative for DHCP (though - DHCPv6 can still be used). With RAs, Your devices will automatically find the - information they need for routing and DNS. - -Multiple LAN/DMZ Setup -====================== - -In this, you use the `Routed /48` information.

The local zone is -the firewall itself. - -If your computer is on the LAN and you need to SSH into your VyOS box, -you would need a rule to allow it in the LAN-Local ruleset. If you want -to access a webpage from your VyOS box, you need a rule to allow it in -the Local-LAN ruleset. - -In rules, it is good to keep them named consistently.

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.

Build out the rulesets for each -zone-pair-direction which includes at least the three state rules. Then -I setup the zone-policies. - -Zones do not allow for a default action of accept; either drop or -reject. It is important to remember this because if you apply an -interface to a zone and commit, any active connections will be dropped. -Specifically, if you are SSH’d into VyOS and add local or the interface -you are connecting through to a zone and do not have rulesets in place -to allow SSH and established sessions, you will not be able to connect. - -The following are the rules that were created for this example (may not -be complete), both in IPv4 and IPv6.
