AbstractCurrently, there does not exist a simple and dynamic mechanism for routers running IS-IS to learn about symbolic hostnames. This document defines a new TLV which allows the IS-IS routers to flood their name to system ID mapping information across the IS-IS network.
There are several ways one could build such a table. One is via static configurations. Another scheme that could be implemented is via DNS lookups. In this document we propose a third solution. We hope the proposed solution is easier and more manageable than static mapping or DNS schemes.
subset of it is strongly recommended. The content of this value is a domain name, see RFC 2181. The string is not null-terminated. The systemID of this router can be derived from the LSP identifier. If this TLV is present in a pseudo node LSP, then it should not be interpreted as the DNS hostname of the router. 1] and it is being enhanced within IETF in .
