IS-IS is an interior gateway routing protocol developed originally by OSI and used with IP extensions as IGP. This draft describes how to effectively bypass the problem of 255 circuits that IS-IS allows to maintain with minor violations of the specification that however does not prevent interoperability with existing implementations.}, }
