cef + vrf bug in 12.3 ios?

i configured cef and vrf routing:

ip cef

!

ip vrf lan

rd 300:1

route-target export 300:1

route-target import 300:1

route-target import 200:1

!

ip vrf vrf1

rd 100:1

route-target export 100:1

route-target import 100:1

route-target import 300:1

!

ip vrf vrf2

rd 200:1

route-target export 200:1

route-target import 200:1

route-target import 300:1

!

interface GigabitEthernet0/0

ip vrf forwarding lan

...

!

interface GigabitEthernet0/1

ip vrf forwarding vrf1

...

!

interface GigabitEthernet1/0

ip vrf forwarding vrf2

...

!

ip route vrf lan 0.0.0.0 0.0.0.0 GigabitEthernet0/1

ip route vrf lan 0.0.0.0 0.0.0.0 GigabitEthernet1/0

when i send ping from vrf lan to vrf1, it doesn't work so well:

!.!.!

if i disable cef, it work fine.

i tried to delete vrf 2 and just route to vrf1, still no luck.

i used 3825 with ios 12.3, ip base. i upgraded to 12.4 spservices, and now it works.

same thing happend to me with 3845.

by the way, it does work with 3845 12.4 ipbase ios.
