[Idr] Configuration objects in BGP MIB v2: Call for consenus
by Jeffrey Haas 06 Jul '08

06 Jul '08

Please pardon this intrusion in the usual operational chatter. I have been working on the successor to the BGP MIB within IETF over the last several years. As part of a review of the current draft of this MIB (http://tools.ietf.org/html/draft-ietf-idr-bgp4-mibv2-07) I have been requested to gather operational consensus regarding being able to configure your BGP peering sessions from within the MIB. Please see the forward below for the details. The BGP MIBv2 is attempting to address some operational holes with regards to the current BGP MIB. These issues include IPv6 support and also better counters for your peering session. In addition to feedback on the configuration objects issue I'd appreciate general feedback on the MIB on or off the list. My goal is to resolve all remaining open issues with the MIB within the next few months and get it into working group last call. A reference implementation in Quagga will likely follow. -- Jeff ----- Forwarded message from Jeffrey Haas <jhaas(a)pfrc.org> ----- Date: Sun, 6 Jul 2008 21:50:00 -0400 From: Jeffrey Haas <jhaas(a)pfrc.org> To: idr(a)ietf.org Subject: [Idr] Configuration objects in BGP MIB v2: Call for consenus Working Group, Back around 2005 I had a number of discussions with people who had provided input for the BGP MIBv2 work. These conversations were specifically regarding the configuration objects in the MIB. draft-ietf-idr-bgp4-mibv2-05 was the last version of the MIB that contained the proposed configuration objects. The results of those discussions were effectively that the configuration mechanisms in that MIB were too complex and had some potential issues. In particular: - Modern BGP implementations tend to be more complex than the feature set covered by the proposed MIBs. It was not possible to configure all session specific features from the MIB. Since the base MIB is not intended to cover all possible current and future features this is problematic. - Configuration of peering sessions are not sufficient to fully implement BGP in an operational network. BGP fundamentally requires policy for the population of the Ribs. Policy elements and algebra vary considerably among vendors. Providing a general policy engine for BGP in the MIB is likely out of scope of this work. Presume that the structural issues from draft-05 may be addressed. Should they be addressable, do we wish to pursue including configuration objects in the BGP MIB? Given the operational impact of this issue, I would appreciate it if this call for consensus was distributed within and without IETF. I will be forwarding this to NANOG as a first step. -- Jeff

Jim, ATM I have exchange set to dis-allow outbound mail, just to be safe. I want to have something more then just a simple home-level nat box before I allow anything more out, pending a full while and re-load. The damage done was to the box itself. The few pieces of email that needed to go out this weekend (seven or eight, I think) used my personal mail server as the outbound. Forgive me if I'm not making any sense, I've been burning the candle at both ends... ~Nick -----Original Message----- >From: Jim Popovitch <yahoo(a)jimpop.com> >Sent: Jul 6, 2008 11:55 AM >To: nanog <nanog(a)nanog.org> >Subject: Re: tacid.org > >On Sun, Jul 6, 2008 at 11:09 AM, Nick Shank <nick(a)laststop.net> wrote: >> After doing a bit of digging, it doesn't appear the any of the tacid.org ip-space is blacklisted (one less >> battle I have to fight).

Greetings, My name is Nick, and I have inherited admin duties for tacid.org. For an un-known amount of time (A month or more?) mail.tacid.org has been an open-relay, and sending out large amounts of spam. This should now be fixed.

Re: REJECT-ON-SMTP-DATA (Re: Mail Server best practices - was: Pandora's Box of new TLDs)
by Jean-François Mezei 05 Jul '08

05 Jul '08

one note about whether to filter at receiving SMTP server or later. The receiving SMTP server is the one that has the conversation with the sender. Rejecting mail from servers having an un-backtranslatable IP is best done right away by the receiving server right after the HELO command by issuing error message about the IP being unbacktranslatable. Reduces the load. later on (for instance at the client level), you need to parse the RFC822 text header and there are some bits that are missing, notably the RCPT TO: commands. This is especially true when the "TO" in the 822 header is faked. Blocking messages as early as possible also greatly reduces the load on your system, disk storage requirements etc.

Replacement for Avaya CNA/RouteScience
by Drew Weaver 05 Jul '08

05 Jul '08

Howdy for reasons it might be inappropriate to discuss on this list we've decided that we're going to replace our Avaya/RouteScience box and we're looking for recommendations on different solutions for 'BGP management appliances'. We're aware of the Internap FCP product, but is there anything else out there besides 'oy, hire a BGP admin ya tool!' that anyone can offer? As always, comments are appreciated. -Drew

ICANN opens up Pandora's Box of new TLDs
by Jim Popovitch 05 Jul '08

05 Jul '08

Two years ago I posed the question here about the need for TLDs (http://www.mcabee.org/lists/nanog/May-06/msg00110.html) I summerizsed that companies IP (Intellectual Property) guidelines would never allow domain.org to exist if they owned domain.com (ibm.org vrs ibm.com) I felt that TLDs really represented a monetary harvesting scheme as every new TLD forced companies to "pay for yet another domain name" (slowly milking businesses). At that time several knowledgeable folks commented that TLDs were necessary in the beginning due to the need to distribute queries. Now it seems, ICANN has decided to add a new paradigm :-) How will a TLD like .ibm be handled now, and how is this different than what I proposed in 2006? -Jim P.
