IS-IS, originally designed for Open System Interconnection (OSI) routing, uses TLV parameters to carry information in Link State Packets (LSPs). The TLVs make IS-IS extendable. IS-IS can therefore carry different kinds of information in the LSPs. Several routing protocols use TLVs to carry a variety of attributes. Cisco Discovery Protocol (CDP), Label Discovery Protocol (LDP), and Border Gateway Protocol (BGP) are examples of protocols that use TLVs. BGP uses TLVs to carry attributes such as Network Layer Reachability Information (NLRI), Multiple Exit Discriminator (MED), and local pReference: The IP header of the EIGRP packet specifies IP protocol number 88 within it, and the maximum length of the packet will be the IP MTU of the interface on which it is transmitted, most of the time "Pass Any Exam.

These TLVs will not only carry the route entries but also provide fields for the management of the DUAL process, multicast sequencing, and IOS software versions from the router.
