-Route-Based Redundant Site-to-Site VPN to Azure (BGP over IKEv2/IPsec) ----------------------------------------------------------------------- - -This guide shows an example of a redundant (active-active) route-based IKEv2 -site-to-site VPN to Azure using VTI -and BGP for dynamic routing updates. - -Prerequisites -^^^^^^^^^^^^^ - -- A pair of Azure VNet Gateways deployed in active-active - configuration with BGP enabled. - -- A local network gateway deployed in Azure representing - the Vyos device, matching the below Vyos settings except for - address space, which only requires the Vyos private IP, in - this example 10.10.0.5/32 - -- A connection resource deployed in Azure linking the - Azure VNet gateway and the local network gateway representing - the Vyos device. - -Example -^^^^^^^ - -+---------------------------------------+---------------------+ -| WAN Interface | eth0 | -+---------------------------------------+---------------------+ -| On-premises address space | 10.10.0.0/16 | -+---------------------------------------+---------------------+ -| Azure address space | 10.0.0.0/16 | -+---------------------------------------+---------------------+ -| Vyos public IP | 198.51.100.3 | -+---------------------------------------+---------------------+ -| Vyos private IP | 10.10.0.5 | -+---------------------------------------+---------------------+ -| Azure VNet Gateway 1 public IP | 203.0.113.2 | -+---------------------------------------+---------------------+ -| Azure VNet Gateway 2 public IP | 203.0.113.3 | -+---------------------------------------+---------------------+ -| Azure VNet Gateway BGP IP | 10.0.0.4,10.0.0.5 | -+---------------------------------------+---------------------+ -| Pre-shared key | ch00s3-4-s3cur3-psk | -+---------------------------------------+---------------------+ -| Vyos ASN | 64499 | -+---------------------------------------+---------------------+ -| Azure ASN | 65540 | -+---------------------------------------+---------------------+ -
