Deafult route propagation in MPLS

Hi,

(Default Route <------) CE1------PE1---P----PE2---CE2(--->Default Route)

In  above, Let CE1 and CE2 have default static route monitored with IP SLA.  CE and PE ospf running OSPF. The target is, if IPSLA on CE1 becomes  invalid, the static default route shuld disappear from CE1 and it should  get default route via CE2 and so on viceversa for IPSLA of CE2 is  down...

I tried above scenario on GNS3 it worked but when i  tried on real environment, i always needed to clear OSPF process of PE. I  have IOS-XR with v3.9.2. If is do not clear OSPF process, i will still  see PE pointing  default route towards CE ( where static default route  is invalid) but in CE, i see default route towards PE .

I guess it is bug of IOS-XR V  3.9.2.
