ISIS over FR-FR L2VPN

I have setup a FR to FR layer 2 VPN (l2tpv3).

CE1----fr---PE1--------PE2----fr----CE2

L2TP tunnel is showing up on both the PE routers. I am able to ping remote
interface from both the CE routers as well. MPLS Neighborship is also
getting established between CE1 and CE2. I have tired configuring OSPF and
OSPF neighborship comes up with out any issue.

But when I try to configure ISIS on CE1 and CE2 it's not working.
neighborship is not coming up at all. pls find below the config of both the
CE router. Am I missing something here for ISIS config ???? . There is not
mismatch of interface type. I can't make out with anything in debug as well
