This draft is a work item of the IS-IS for IP Internets Working Group of the IETF.
Title : Restart signaling for IS-IS
Author(s) : M. Shand, L. Ginsberg

The IS-IS routing protocol (RFC 1142 [2], ISO/IEC 10589 [3]) is a
link state intra-domain routing protocol. Normally, when an IS-IS
router is re-started, the neighboring routers detect the restart
event and cycle their adjacencies with the restarting router through
the down state. This is necessary in order to invoke the protocol
mechanisms to ensure correct re-synchronization of the LSP database.
However, the cycling of the adjacency state causes the neighbors to
regenerate their LSPs describing the adjacency concerned. This in
turn causes temporary disruption of routes passing through the
restarting router.
In certain scenarios such temporary disruption of the routes is
highly undesirable.

In the body type:
"FILE /internet-drafts/draft-ietf-isis-restart-03.txt".
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
Internet-Draft.
