Technical Tip: VPN4 ,VPN6 and EVPN Address Family for BGP in FortiOS

[Jackie_T]

Description	This article describes that the most common address families are IPv4 and IPv6. For BGP and MPLS, it is possible to have VPN-IPV4/IPv6 as well. EVPN, VPNv4  and VPNv6 address family configuration tells what the supported routing information in a single BGP session is. As of v7.2.0, the VPNv4 address family has been added to the supported address families. As of v7.4.0, the EVPN and VPNv6 address families have been added to the supported address families.
Scope	FortiGate v7.2.x, v7.4.x and v7.6.x
Solution	Starting from v7.2.0 VPN-IPv4 and from v7.4.0 EVPN and VPN-IPv6 are supported by default and this feature is enabled by default. Below are the command line settings: In v7.2.0+: config router bgp     config neighbor         edit <neighbor>             set activate-vpnv4 enable  end In v7.4.0+: config router bgp     config neighbor         edit <neighbor>             set activate-vpnv4 enable              set activate-vpnv6 enable                  set activate-evpn enable       end        If the remote BGP neighbor does not support EVPN ,VPNv4 and VPNv6 address family, it is necessary to disable the feature by setting it to disable: config router bgp     config neighbor         edit <neighbor>             set activate-vpnv4 disable             set activate-vpnv6 disable             set activate-evpn disable end
