[j-nsp] MX IRB & SRX cluster OSPFv3 problem

Folks,

Here's my situation.

I have an MX5 configured to dual-homed to two sets of SRX240 in a cluster with the intention of running OSPF + BGP between them.

The links are straight point to points with no switch in between.

OSPF between the two works alright, so does static. BGPv4 and BGPv6 (static routing) works OK.

My problem is with OSPF3, no matter what I configured, the session just won't come up.

Curiously, the link-locals are not seen on both sides.

        Destination: fe80::/64, Local: fe80::210:dbff:feff:1000

ihsan at b1> show interfaces irb.0 | match fe80 
        Destination: fe80::/64, Local: fe80::aad0:e5ff:fe52:f828

The OSPF3 hellos are sent out on both sides but only the MX is not receiving hence the current state of OSPF3 Init on the SRX.

The config is just plain routing. No fancy MPLS, CoS stuff etc.

I have another MX5 and SRX240, plain routing with IPv6, without cluster and IRBs. OSPFv3 works alright.

So I'm guessing it's either the cluster setup or the IRB or maybe combo of both.

I'm on 11.4R3.7.
