Vishwas -
	Looking at the MIB, this TC is used
a number of places where the level -is-
well defined, but it is also used in 
Notifications.  If, for example, you 
get a packet with a different version
number, you don't really know the level
of the packet, and would use "none" in
the notification.

RE: draft-ietf-isis-wg-mib-11.txt

Jeff,

Are you saying that a value of "none" would be wrong in this particular
case?

Thanks,
Vishwas

New Version of draft-ietf-isis-restart


Folks -

Mike Shand and I have submitted V3 of draft-ietf-isis-restart (V2 was 
withdrawn from last call at our request). Since we submitted it close to 
the deadline, it may take a while for the official announcement to appear.

In addition to making some clarifications based on review comments from the 
list, the new version includes the following changes:

1)We now make explicit that the LANID must be ignored in IIHs having the RR 
bit set. This is something that implementation experience shows is 
necessary. As it affects the bits on the wire (what is sent as LANID by 
neighbors of the restarting router) it seemed necessary to explicitly state 
this in the draft.

2)New functionality in the case of a starting (NOT restarting) router is 
defined to prevent the potential occurrence of transient blackholes due to 
the presence in the network of LSP fragments from a previous incarnation of 
the starting router.

3)The text in the draft has been restructured to more clearly show the 
commonalities and differences in behavior between the restarting and 
starting cases.

Finally, and MOST IMPORTANT, implementations based on the old version(V2) 
of the draft will interoperate with versions based on the new draft, though 
of course the new functionality will not be supported.

Cheers.

RE: draft-ietf-isis-wg-mib-11.txt

Hi Jeff,

Some minor comments. Does the isisLSPTLVIndex mean the offset in bytes from
the header or the TLV number(like the first/second/nth TLV) in the contents
of the LSP?

I think its the latter. It would be nice if this was clarified further in
the "DESCRIPTION".

Besides I am not sure if I have asked you for this, but can we change
isisLSPTLVSeq to isisLSPTLVLSPSeq and isisLSPTLVChecksum to
isisLSPTLVLSPChecksum.

Also in isisLSPID description you can replace the "Fragment Number" as "LSP
Number" in isisLSPSummaryTable.

Thanks,
Vishwas

draft-noguchi-isis-protocol-topology-01.txt

Hi all,

This is Kay.

I updated our draft, Protocol Topology Support for IS-IS.
You can download it from the ietf site with this URL.

http://ietf.org/internet-drafts/draft-noguchi-isis-protocol-topology-01.txt

The change includes,

 - it makes clear the adjacency section as Jeff suggested.
 - it adds one section which discribes "Migration from Node Oriented
   to Interface Oriented Protocol Support".

I'll make a presentation in the next IETF so hope you guys read the
draft before the meeting.

Thank you,

								kay

Good point.  Is this clearer?

    isisLSPTLVIndex OBJECT-TYPE
        SYNTAX Unsigned32
        MAX-ACCESS read-only
        STATUS current
        DESCRIPTION
            "The index of this TLV in the LSP.  The first TLV has index 1,
		 the Nth TLV has an index on N."

Remind me why is this a good idea.

Nagi -
	Good point.  I have modified the text of the Description clause,
included below.  The isisSysLevelSetOverload object remains read-create.  It
is also included below for reference.
	The LevelState TC includes both overloaded (natural causes) and
waiting (set by administrator) so that a manager can tell why the system's
overload bit is set.

    LevelState ::= TEXTUAL-CONVENTION

            "States of the IS-IS protocol."

wish from them).
