Editor's Note: Minutes received 12/12/92
CURRENT_MEETING_REPORT_
Reported by Matt Mathis/PSC
Minutes of the BGP Deployment Working Group (BGPDEPL)
The immediate Agenda of the BGP Working Group is to expedite BGP-4
deployment in the Internet. At this moment none of the vendors have
BGP-4 code running. Network operators are all waiting on their vendors,
and our task is to encourage the vendors to complete BGP-4 as soon as
possible.
The AS path tree collected from Pittsburgh was discussed (attached below).
Of the approximately 5000 networks which are currently reachable,
almost 3000 are being originated with EGP2. No
single AS originating more than 100 networks is using BGP at all,
including all other US Backbones and large regionals. NSFnet, Ebone,
CAnet, a few mid-sized regionals, and ANS stub customers account for all
deployed BGP in the Internet today. Four mid-level operators
(representing relatively large networks) indicated that they had tested
BGP-3, and had reverted to EGP2 because their vendor's implementations
to be missing some features required in their environment. (Note that
there are several BGP based transit networks including ANS, AlterNet,
Sprint and the EBone, but these originate relatively few networks.)
This situation is pretty bleak. There is only a short time available to
test and deploy BGP-4, and operators whom have not yet deployed BGP-3
will face additional difficulties phasing out EGP2. It is desirable for
all network operators to have BGP experience as soon as possible.
Implementor reports:
ANS Currently has a ``routed'' implementation of BGP-1
and BGP-2 running in the backbone. Will be
converting to ``gated'' in January or early February
(This will deprecate BGP-1). They expect to begin
testing BGP-4 w/CIDR in the production backbone
during 1Q93.
cisco Currently support BGP-2 and BGP-3. Chose not to
announce plans or timetable for BGP-4.
Wellfleet Plans to have BGP-3 in summer of 93 and BGP-4
sometime after. EMPB - PTT Telecom, The
Netherlands). Will have BGP-3 Soon. Uncertain
about schedule for BGP-4.
IBM (Networking Systems at RTP) - BGP-3 has been
announced for 6611 router in 2Q93.
1
3Com Hopes to be testing BGP-4 by March, for possible
release by August.
BBN BGP-3 is currently deployed in T20's. They are
working on BGP-4. Proteon was not represented, but
several of their customers (who were present) have
been promised BGP-4 in April 93.
Claudio Topolcic, from CNRI, presented RFC1366 and RFC1367, the proposed
addressing plan and schedule to deploy CIDR. This served to initiate a
general discussion about timetables.
The consensus was that the following schedule is reasonable:
1/93-3/93 BGP-4 interoperability testing with the ANS testing
facility (See below - all vendors are invited to
participate).
3/93 BGP-4 capable code deployed in the production NSFnet
backbone. Begin testing by propagating some
non-production/non-ABC networks through the
backbone.
6/93 Start aggregating *production* networks in the
backbone.
12/93 Completely phase out all EGP2 on NSFnet DMZs.
There was some discussion about how this interacts with the new network
assignment rules and schedule specified in RFC1366 and RFC1367. It was
noted that 8 of the operators present had already obtained contiguous
blocks of 256 class C addresses in advance of the formal plan. This has
two implications: Since the NIC does not track assignments which are
slated for subsequent reassignment, current growth figures are
exaggerated by at at least 2000 networks and probably more.
Clusters of Class C networks will start appearing before predicted by
RFC1367. This may slightly steepen the growth of the routing tables but
most of the operators were not concerned. Several pointed out that most
mature technology companys already had old network numbers. At the
regional level most of the sites requesting new numbers were new to IP
networking, and even if they had plans for hundreds or thousands of IP
hosts, they currently only needed to announce one or two class C
networks out of their entire block.
The first aggregation of production networks (scheduled for June 1993)
will be a flag day for any site requiring full routing tables and not
running BGP-4. There are only a few sites which may find them selves in
this situation. All others can use default to route to their favorite
2
backbone/mid-level provider. The sites which require full routing
tables are either enforcing AUPs or implement optimal routing to
multiple backbones or mid-levels. In the latter case, not having BGP-4
will result in non-optimal routes for the aggregated networks only.
This is not viewed as a show stopper. However, if some organization has
a mission requirement to enforce an AUP but can not deploy BGP-4 by June
1993, there will be pressure to slip the schedule. This must be
balanced against the cost to everyone else of carrying ever growing
non-CIDR routing tables.
We also considered the scenario where BGP-4 isn't deployed on time for
some reason (e.g., finding a serious bug in the specification.) Our
conclusion was that the above discussion also applies, as long as the
NSFnet backbone can still hold the routing table for the entire
Internet. All other providers can (in principle) use the default to
reach the NSFnet when they can no longer hold the entire routing table
themselves. As a corollary, the Internet will survive the RO+AD crisis,
if and only if, at least one network provider implements a solution. If
no solutions are successful, the network provider of last resort will be
blamed, even if the problem has become intractable.
Jordan Becker (ANS) estimated that full route aggregation will reduce
the current routing tables by about 30%, because the old address
assignment policies tended to allocate addresses in blocks anyhow.
Jordan repeated his invitation for all router vendors to make use of the
ANS test facility for BGP interoperability testing. Vendors can make
arrangements to bring equipment to the test facility, or to do remote
testing through a ``wide areax'' BGP session across the internet.
Contact him for further information (becker@ans.net).
Dennis Ferguson (ANS/gated implementor) announced that he had avoided
implementing the supernet expansion code, which would map BGP-4
supernets into a block of BGP-3 class C networks. He was concerned that
this is difficult to do correctly and unlikely to be useful for very
long. After some discussion it was observed that the 8 blocks of 256
class C networks represented in the room would be announced as 8 BGP-4
routes as soon as prudent. These would in turn map to 2048 class C
BGP-3 routes, which are likely to immediately overwhelm any BGP-3
router. Ergo the supernet expansion code would probably be useful for
less time than it would take to debug it. The BGP Deployment Working
Group concurs that implementing the supernet expansion code would not be
cost effective.
Tony Li of cisco made an interesting point about software release
schedules. Releases are typically on a 6 month cycle with an 8 month
lead time between code freeze and ``first customer ship'' (aka:
beginning of General Availability for some new feature). Cisco's next
scheduled code freeze is February 93, so even if bug-free BGP-4 code
exists today the earliest it will appear in General Availability
products is October 1993. All customers who need BGP-4 before then must
run pre-GA code. Other vendors were in general agreement. Some of the
operators were upset - one was operating under a prohibition against
using non-GA code.

The fields in each line of the AS path tree are:
- dots.. for above listed AS's also traversed to reach this AS.
- AS number
- BGP origin field,
UNKNOWN -> transit across the T1 NSF net (origin is missing)
TRANSIT -> No nets originate in this AS, ergo no origin field
others are as described in the BGP RFCs ;-)
- (net count) Number of networks carried by this AS path
- NIC name - one token from asn.txt
- Merit DB name - Additional name information from Merit's as-as3.now
There are a number of artifacts which limit the completeness of this data:
- It was collected from AS 1206 (PSCnet) which does not appear in the list
- AS 1206 is dual connected, such that most networks (and AS's) should
appear twice - Once via AS 145 and once via AS 690.
- AS 1206 is ``NSFnet AUP compliant'' and does not get CIX or other commercial
routes.
- Some international routes are excluded as well.
- This is collected from a snapshot of live routing tables, and at the time
there were are least 3 open tickets at the Merit NOC.
- This is only the ``spanning tree'' used to reach Pittsburgh. Other links do
not appear.
