IPV6 BGP flapping caused by duplicate OSPFV3 router ID

[Herlianto]

Hi All,

We have deployed IPV6 over IPV4 tunnel, but at some site we facing the
problem for BGP and OSPFV3.

The BGP Flapping and at the log there is command as shown below :
Aug  9 08:08:39.089: %OSPFv3-4-DUP_RTRID_AREA: Detected router with
duplicate router ID x.x.x.x in area 0
Aug  9 08:09:46.644: %OSPFv3-4-DUP_RTRID_AREA: Detected router with
duplicate router ID x.x.x.x in area 0

for OSPF V3  with the command : #show ipv6 ospf neighbor there is some
different interface tunnel but the neighbor ID is same

Is there any experience and any suggestion to solve it ?

Thanks for your kind attention and cooperation.
