This draft describes a limited flooding approach to address the
problem of routing scalability in link state IGPs. The solution is
based on decomposition of a routing area into 'zones' and the
restriction of the exchange of routing information between zones.
This approach introduces an extra level in the isolation of
knowledge within a routing domain. The advantage of this solution is
that it considerably decreases the amount of information flooded in
link state advertisements and reduces the size of the link-state
database (and traffic engineering entries) on network elements
utilizing link state protocols. The technique presented in this
document has been particularized to OSPF in order to make the
discussion practical and concrete. However, the underlying concepts
are very general and similar modifications can be easily applied to
other IGPs, such as ISIS.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
