We study the reaction cross sections of ^<11>Li projectile on various targets at high projectile enery E_<lab>/A=800 MeV. The cross section due to the nucleonic interaction is calculated by using a simple Glauber model, while that due to the electromagnetic interaction is obtained by assuming the break-up process through the giant dipole resonance of the projectile. The small separation energy of two neutrons outside ^9Li core enhances significantly both the cross sections of ^<11>Li projectile, especially on heavy targets. The calculated cross sections reproduce fairly well the experimental data except Pb case. The calculations are also performed in a medium energy case with E_<lab>/A=40 MeV taking into account both the electric dipole and quadrupole contributions.
