OSPF v3- neighbors bouncing

I have configured point to multipoint ipv6 frame-relay for OSPF v3 between
R3, R4 and R6. I am unable to form "Full" state neighbor relationship.

For some reason, neighbor relationship is bouncing between init and Exstart.
As soon as it reaches full state, it bounces back to init. Kindly help.

Here sre the configs.

*R6*
interface Serial0/0/0.346 multipoint
 ip address 110.1.0.6 255.255.255.0
