Hello Manoj,
First step would be to remove ip ospf priority 0 on R6 Serial interface,
this is not needed, because ospf is configured with a point-to-multipoint
network type. Its only needed where when you trying to prevent the router
from becoming a DR in a broadcast, non-broadcast or point-to-multipoint
non-broadcast network type. Also check your MTU settings to see if you have
set the mtu on the interface. Also if you may want to remove ospf protocol
reload the router, and reenter the ospf configuration.
Sincerely,
John
