This causes the contents of many critical TLVs to exceed the currently supported limit of 255 octets. Extensions such as {[}RFC7356{]} require significant IS-IS changes that could help address the problem, but a less drastic solution would be beneficial. This document codifies the common mechanism of extending the TLV space through multiple TLV instances.}, }
