SD-WAN support for ADVPN  6.2.1

With this feature, SD-WAN service rules can utilize the shortcut VPN to forward traffic between spokes. Previously, spoke to spoke traffic could only be forwarded by the hub, and could not take advantage of the ADVPN feature.

This user ADVPN with SD-WAN scenario uses two hubs, and each spoke connects to two ISPs and establishes VPN tunnels with each hub.

SD-WAN is configured on the spokes, and uses two VPN interfaces as members with rules to control traffic to other spokes via the ADVPN shortcut VPN interfaces.

To configure a hub:
  1. Configure the IPsec phase1 and phase2 interfaces:
    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 firewall policies:

            set srcaddr "all"
            set dstaddr "11.11.11.0"
            set action accept
            set schedule "always"
