An information processing apparatus includes a first port coupled to a first network, a second port coupled to a second network, a first memory, and a first processor coupled to the first memory and configured to execute first routing processing related to communication performed by the information processing apparatus and a first information processing apparatus coupled to the first port through the first network, execute second routing processing related to communication performed by the first information processing apparatus and a second information processing apparatus coupled to the second port through the second network, when a failure occurs in the first port, cause a third information processing apparatus coupled to both of the first and second networks to execute the first routing processing, and when a failure occurs in the second port, cause the third information processing apparatus to execute the second routing processing.
