Technical Summary

Increasing use of IS-IS for the flooding of information not directly used
by the primary protocol function has created a need for a generalized
method for incorporating said new information without impacting the primary
IS-IS protocol function. This specification provides this method.

Working Group Summary

There consensus was strong for this specification. Discussions regarding
this specification primarily involved which extensions the specification
would apply to.

Document Quality

There are currently no implementations of this specification. This
specification is required to be in place so that new applications may then
utilize it in their design. 


Chris Hopps ( is the Document Shepherd for this document.
Stewart Bryant ( is the Responsible Area Director?  

The Document Shepherd is one of the IANA Experts, thus we can assume the IANA 
review expert review has already taken place. The new registry created needs an expert 
and this should be the same expert as for the other ISIS registries.

L1/L2 Router in every area of the domain MUST support the GENINFO TLV.

   given Application MAY introduce new security issues.
