    which one is valid

    The entire bridged LAN uses a single spanning tree instance. When the network is large, a longer convergence time is required or the topology changes frequently.
    Suggested:

    Is this fine? Will the meaning change with or and otherwise?

    Re: which one is valid

    To answer your question, yes it does change the meaning; but I think neither version is right.

    I think what they're trying to say in the second sentence is 'When the network is large, or the topology changes frequently, a longer convergence time is necessary.' This is different from both the original and your suggestion, but it makes more sense (because, if the topology changes frequently, the routing nodes have to do more work storing, updating, transmitting, and maintaining the routing tables).
