In a IS-IS network, each IS router advertises one or more IS-IS Link State Protocol Data Units (LSPs) with
routing information. Within each LSP, there is a fixed header and a number of TLVs with encoded
information. The following command is used to show details of a LSP in detail to a specific neighbor
displaying the encoded information in the TLVs.
