Hmm...okay. How old is this book? They are using 'Network boundary' to refer to the classful major network supernet.
I'm still confused by their use of NIC number and that's because they are NOT referring to the Network Interface Card like most of us would expect. They appear to be referring to an allocated network prefix from the Network Information Center which, as far as I know, isn't around anymore. You get allocations from ARIN, RIPE, and APNIC now. So, knowing that, let me translate: "BGP-4 and EIGRP summarize at the major classful network boundary automatically. [This behavior can be disabled by use the 'no auto-summary' command.] Summarization to a non-classful boundary must be done manually."

Here are a couple of quotes from the Cisco Press book I am reading to show the context in which they use the terms: "BGP-4 and EIGRP summarizes at the network boundary automatically. Summarization within the NIC number boundary must be configured manually." Then when talking about the characteristics of a classless routing protocol: "Some routes can be summarized within the major NIC number. This is done manually." Confused? I am! Regards, James.
