    What is the switch model? You may be hitting the maximum number of routed interfaces, so check the release notes for your switch model and firmware version. Our C3/G3/B5 switches have a maximum of 24 routed interfaces, where our C5 has 48 maximum routed interfaces.

    Thanks Ryan for your answer.

    It is correct, reviewing the configuration I have 24 virtual interfaces.
    The model of the switch is B5K125-48P2

    I will look for information about it to present to my superiors, thank you very much for your help.
