Title : IS-IS Multi-Instance
Author(s) : S. Previdi, et al.
Filename : draft-ietf-isis-mi-04.txt
Pages : 10

This draft describes a mechanism that allows a single router to share
one or more links among multiple Intermediate System To Intermediate
System (IS-IS) routing protocol instances.
Multiple instances allow the isolation of resources associated with
each instance. Routers will form instance specific adjacencies,
exchange instance specific routing updates and compute paths
utilizing instance specific Link State Database (LSDB) information.
Each Protocol Data Unit (PDU) will contain a new Type Length Value
(TLV) identifying the instance to which the PDU belongs. This allows
a network operator to deploy multiple IS-IS instances in parallel,
using the same set of links when required and still have the
capability of computing instance specific paths. This draft does not
address the forwarding paradigm that needs to be used in order to
ensure data PDUs are forwarded according to the paths computed by a
specific instance.
