Yes ,
This unicast route is or ISIS learned or OSPF learned ( I even configured
this RP address as an static route and it didn't help ).

So the problem is that when you had OSPF configured, your S-DR sent
registers and everything worked fine. But when you switched to ISIS, it
stopped sending registers?

Can you send me your config before and after the change, as well as the
'show pim join <group> extensive' and 'sho route <rp address>' and 'sho
chassis hardware'.

Feel free to send this to me directly if you prefer.
