[j-nsp] OSPFv3 interoperability with another vendor

Hi,

I'm testing OSPFv3 with another vendor and unable to get it UP, the session
is stuck in ExStart. (no MTU mismatch)

On another vendor router I see following error :

%OSPF3-7-NBR: OSPF3-1: 192.168.1.4 EVENT: 
Sequence Mismatch STATE:*
> 
%OSPF3-7-PKT_ERRORS: OSPF3-1
STATE: Exchange NBR fe80::219:e2ff:fe5e:78db bad DD flags: MS,M,I*


Config on Juniper:

jun at AR1-2# show protocols ospf3   
traceoptions {
    file ospf3-debug;
    flag all detail;
}
area 0.0.0.0 {
    interface ge-1/3/0.0;
    interface lo0.0;
}
