Having an issue with Tunnel in up/down state, preventing RIPng to work properly.

 As per DOC-Cd the new address remains in a tentative state while
duplicate address detection is performed.

R4#sh ipv6 interface tunnel0
Tunnel0 is up, line protocol is down
  IPv6 is enabled, link-local address is FE80::9601:404 [TENTATIVE]
  Global unicast address(es):
    2001:CC1E:1:4545::4, subnet is 2001:CC1E:1:4545::/64 [TENTATIVE]

R5#sh ipv6 interface tunnel0
Tunnel0 is up, line protocol is down
  IPv6 is enabled, link-local address is FE80::9601:505 [TENTATIVE]
  Global unicast address(es):
    2001:CC1E:1:4545::5, subnet is 2001:CC1E:1:4545::/64 [TENTATIVE]

Ping to 183.1.0.4 is success so frame relay is fine.
