Juniper Route based VPN wth Failover VPN

This example was taken from the Juniper Concepts and Examples guide located here:
http://kb.juniper.net/kb/documents/public/VPN/Interface_Failoverv14.pdf

set interface "tunnel.1" zone "Untrust"
  Tunnel.1 should be the next available tunnel interface. Untrust represents the interface that terminates the VPN

set interface "tunnel.2" zone "Untrust"
   This is the failover tunnel

set interface tunnel.1 ip unnumbered interface ethernet0/2
   Physical interface that terminates the tunnel

set interface tunnel.2 ip unnumbered interface ethernet0/2
set ike gateway "ssg140gw primary" address 3.3.3.1 Main outgoing-interface "ethernet0/2"
