ADVPN with BGP as the routing protocol

This is a sample configuration of ADVPN with BGP as the routing protocol. The following options must be enabled for this configuration:

  • On the hub FortiGate, IPsec phase1-interface net-device disable must be run.
  • IBGP must be used between the hub and spoke FortiGates.
  • bgp neighbor-group/neighbor-range must be reused.

Because the GUI can only complete part of the configuration, we recommend using the CLI.

To configure ADVPN with BGP as the routing protocol using the CLI:
  1. Configure hub FortiGate's WAN, internal interface, and static route.
    config system interface
        edit "port9"
            set alias "WAN"
            set ip 22.1.1.1 255.255.255.0
        next
        edit "port10"
            set alias "Internal"
            set ip 172.16.101.1 255.255.255.0
        next
    end   
    config router static
        edit 1
            set gateway 22.1.1.2
            set device "port9"
        next  
    end  		
  2. Configure the hub FortiGate.
    1. Configure the hub FortiGate IPsec phase1-interface and phase2-interface.
      config vpn ipsec phase1-interface

              set interface "port9"
              set peertype any
              set net-device disable
              set proposal aes128-sha256 aes256-sha256 3des-sha256 aes128-sha1 aes256-sha1 3des-sha1

          next
      end

ADVPN with BGP as the routing protocol

This is a sample configuration of ADVPN with BGP as the routing protocol. The following options must be enabled for this configuration:

  • On the hub FortiGate, IPsec phase1-interface net-device disable must be run.
  • IBGP must be used between the hub and spoke FortiGates.
  • bgp neighbor-group/neighbor-range must be reused.

Because the GUI can only complete part of the configuration, we recommend using the CLI.

To configure ADVPN with BGP as the routing protocol using the CLI:
  1. Configure hub FortiGate's WAN, internal interface, and static route.
    config system interface
        edit "port9"
            set alias "WAN"
            set ip 22.1.1.1 255.255.255.0
        next
        edit "port10"
            set alias "Internal"
            set ip 172.16.101.1 255.255.255.0
        next
    end   
    config router static
        edit 1
            set gateway 22.1.1.2
            set device "port9"
        next  
    end  		
  2. Configure the hub FortiGate.
    1. Configure the hub FortiGate IPsec phase1-interface and phase2-interface.
      config vpn ipsec phase1-interface
          edit "advpn-hub"
              set type dynamic
              set interface "port9"
              set peertype any
              set net-device disable
              set proposal aes128-sha256 aes256-sha256 3des-sha256 aes128-sha1 aes256-sha1 3des-sha1
              set add-route disable
              set dpd on-idle
              set auto-discovery-sender enable
              set tunnel-search nexthop
              set psksecret sample
              set dpd-retryinterval 5
          next
      end
      config vpn ipsec phase2-interface
          edit "advpn-hub"
              set phase1name "advpn-hub"
              set proposal aes128-sha1 aes256-sha1 3des-sha1 aes128-sha256 aes256-sha256 3des-sha256
          next
      end
    2. Configure the hub FortiGate firewall policy.
      config firewall policy
          edit 1
              set name "spoke2hub"
              set srcintf "advpn-hub"
              set dstintf "port10"
              set srcaddr "all"
              set dstaddr "172.16.101.0"
              set action accept
              set schedule "always"
              set service "ALL"

              set ip 10.10.10.254 255.255.255.255
              set remote-ip 10.10.10.253 255.255.255.0
          next
      end
