ip route via interface when loopback in bind mode

[dijix1990]

How can I make default route via interface with loopback in bind mode?

interface Loopback1
  tunnel-interface
   encapsulation ipsec
   color red
   bind GigabitEthernet1
   no allow-service bgp
   allow-service dhcp
   allow-service dns
   allow-service icmp
   no allow-service sshd
   no allow-service netconf
   no allow-service ntp
   no allow-service ospf
   no allow-service stun
   allow-service https
   no allow-service snmp
  exit
exit

ip route 0.0.0.0 0.0.0.0  GigabitEthernet1

I think I would use this scenarios:

Lo1 - bind to Ge1.100
Lo2 - Bind to Ge2.200
Lo3 - Bind to Vlan100

Lo1
ip address 10.10.10.1/32

Lo2
ip address 20.20.20.1/32

Lo3
ip address 10.10.10.2/32

Lo1 and Lo2 transport + nat dia for vpn 1

Lo3 nat dia for vpn 2 (custom color and policy)

It difficult config, but it because of cisco doesn't fit to use as isp border in controlled mode
