strange csc behaviour// ip expert lab 9

Hi
I am doing lab9 of IP Expert were with we have a CSC scenario
Troubled topology is simple
R6------R2

R6 has vrf with mpls ip activated towards R2,
ospf running between those two routers
I have direct connectivty between them. OSPF is up and running.
After I activate mpls ip on the link on both routers I loose direct
connectivity between them
I mean ping on directly connected ip address does not work anymore !!!
OSPF stays up.
LDP is also fliping a lot:
I did quite a few of CSC scenarios and this is the first time is happening.

R2(config-subif)#do sh run int ser 4/0.206
interface Serial4/0.206 point-to-point
 bandwidth 2000
 ip address 123.2.6.2 255.255.255.0
 mpls ldp discovery transport-address interface
 mpls label protocol ldp
 mpls ip
 no cdp enable
 frame-relay interface-dlci 206
end

R6(config-subif)#do sh run int ser 4/0.602
interface Serial4/0.602 point-to-point
 bandwidth 2000
 ip vrf forwarding VPNA
 ip address 123.2.6.6 255.255.255.0
 mpls ldp discovery transport-address interface
 mpls label protocol ldp
 mpls ip
 no cdp enable
 frame-relay interface-dlci 602
end
I am doing it on dynamips. I did reboot both routers.
R6(config-subif)#do sh ver | i IOS
Cisco IOS Software, 7200 Software (C7200-K91P-M), Version 12.2(25)S14,
RELEASE SOFTWARE (fc2)
R6(config-subif)#
R2(config-subif)#do sh ver | i IOS
Cisco IOS Software, 7200 Software (C7200-K91P-M), Version 12.2(25)S14,
RELEASE SOFTWARE (fc2)
R2(config-subif)#

Any hint is appreciated.
