<div>I suspect kernel having some internal settings as I don't see any debug message when I do a ping6 to the other node.</div>

<div>If I change the ip -6 route on both nodes to /48 it works fine.</div>

You should be able to add any route with any prefix just fine. But can<br>
you show us the output of "ip -6 route show" and the exact command that<br>
you tried that fails?<br>
