In order to push the IKE and ESP packets for the IPsec, the tunnel needed to be refreshed so removed the crypto map from the physical interface and then reapply it again. Doing this IPsec packets reach to the other end in sync and tunnel reformed hence EIGRP neighbour came up.

Please avoid this solution as can cause reachability issue
