VRF aware VPN

Question

Hi,
I'm trying to set up different types of VRF-aware VPN and I have a problem with below one:
FVRF=VRF1 and IVRF=global, no VRF
there  are 2 routers with Loopback1 (global VRF) and gig0/0 (vrf FVRF). When I  ping between Loop1's I see ISAKMP and IPsec SAs are up but I don't  receive echo reply
Loop1 (global vrf) -- gig0/0 (vrf=FVRF) <-> gig0/0 (vrf=FVRF) -- Loop1 (global vrf)
11.11.11.11                 10.0.0.1                             10.0.0.2              22.22.22.22

I added static routes on r1 and r2 but apparently I missed something else:
r1:
ip route 22.22.22.22 255.255.255.255 GigabitEthernet0/0 10.0.0.2
r2:
ip route 11.11.11.11 255.255.255.255 GigabitEthernet0/0 10.0.0.1
Any suggestions?

Hi,
yes, I have the static route:
r1#sh run | i route
ip source-route
ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0 10.0.0.2
r1#sh ip ro
r1#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, + - replicated route
Gateway of last resort is 10.0.0.2 to network 0.0.0.0
S*    0.0.0.0/0 [1/0] via 10.0.0.2, GigabitEthernet0/0
      11.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        11.11.11.0/24 is directly connected, Loopback1
L        11.11.11.11/32 is directly connected, Loopback1
r1#sh ip route vr
r1#sh ip route vrf FVRF
Routing Table: FVRF

Gateway of last resort is not set

The problem is I can't specify 'global' vrf in the route statement. When I tested a bit different case scenario everything worked fine:
a) Loop1 (vrf=IVRF) -- gig0/0 (global vrf) <-> gig0/0 (global vrf) -- Loop1 (vrf=IVRF)
  11.11.11.11                 10.0.0.1                             10.0.0.2              22.22.22.22
I just added:
ip route vrf IVRF 22.22.22.22 255.255.255.255 GigabitEthernet0/0 10.0.0.2 global
b) With 2 VRFs:
Loop1 (vrf=IVRF) -- gig0/0 (vrf=FVRF) <-> gig0/0 (vrf=FVRF) -- Loop1 (vrf=IVRF)
11.11.11.11                 10.0.0.1                             10.0.0.2              22.22.22.22
I added:
ip route vrf FVRF 0.0.0.0 0.0.0.0 10.0.0.1
ip route vrf IVRF 0.0.0.0 0.0.0.0 FastEthernet0/0 10.0.0.1
So, the problem I have, is only when Loopback interfaces are in global VRF and physical interfaces vrf=FVRF:
Loop1 (global vrf) -- gig0/0 (vrf=FVRF) <-> gig0/0 (vrf=FVRF) -- Loop1 (global vrf)
11.11.11.11                 10.0.0.1                             10.0.0.2              22.22.22.22
I wonder if Cisco supports such scenario.
