Hello Pramod,
post the router isis config
RP/0/5/CPU0:Jul 9 21:46:06.828 : netio[294]: %ROUTING-CLNS-3-ETHERENCAP : Incorrect MAC address length 0
it looks like it is not able to correctly encapsulate the IS-IS PDU on an ethernet frame.
To be noted also that if you are trying to run IS-IS on a management interface this can be part of the problem you shouldn't use it to route user traffic but only for management
Hope to help
