ISTF – The Bulgarian NREN

Main objectives

provision of high-quality networking services to Bulgarian
academic & research institutions

interconnection with the Pan-European and world research
networks (GÉANT2, Abilene, TEIN2, etc.)

Quick Summary(1)
Simplified transition
methodology strategy as implemented in Bulgarian NREN:







Get an IPv6 address space allocation (2001:4b58::/32 )
Deploy an IPv6-enabled router - yes
Arrange external IPv6 connectivity - yes – to GEANT2 network
Enable internal routing – partially - over three major links
Deploy security measures and enable basic networking services
– using the same ACLs as for IPv4
– no IPv6 specific security measures undertaken so far – work in progress;
– only DNS and web services are IPv6 enabled
Enable IPv6 to end-systems – partially on the NOC LAN – FreeBSD, Linux,
Windows XP
Active IPv6 to applications – future work in progress

RIPE IPv6 allocations for Bulgaria

Currently only three IPv6 prefixes are allocated by
RIPE to Bulgarian LIRs

bg.mtelnet
20040331
2001:1ac8::/32

bg.nat
20040406
2001:1ae0::/32

bg.unicom-b
20050201
2001:4b58::/32

The first two allocations are for major Bulgarian ISPs
(MTel and Evolink)

The third allocation is for the Bulgarian NREN (ISTF)

Native international IPv6 connectivity in
Bulgaria

So far, from these three allocated IPv6
prefixes only ISTF advertises its own one
(2001:4b58::/32, origin AS6802) worldwide:

through the SEEREN link Sofia-Athens (01/Feb/2005 – 17/Mar/2005)

through the GÉANT2 link Sofia-Budapest (from 17/Mar/2005 onward)

IPv6 deployment in ISTF’s network
Several ISTF routers have dual-stack configuration:
sofia-broder:
cisco7301-ios C7301-JS-M, Version 12.3(11)T3
sofia-access:
cisco7206-ios C7200-JS-M, Version 12.3(11)T2
tarnovo-access:
cisco2691-ios C2691-ADVIPSERVICESK9-M, Version 12.4(4)T1
plovdiv-access:
cisco2691-ios C2691-ADVIPSERVICESK9-M, Version 12.4(4)T1
pleven-access:
cisco2621xm-ios C2600-IS-M, Version 12.3(3)

IPv6 deployment in ISTF’s network

The central node at IPP-BAS is fully IPv6 enabled,
including the NOC and part of the LAN of IPP-BAS
(most internal traffic is actually IPv6)

IPv6 traffic is also carried over three major links in
the ISTF internal backbone:

Sofia – Veliko Tarnovo

Sofia – Plovdiv

Veliko Tarnovo – MU Pleven (link configured yesterday)

IPv6 enabled services at ISTF


Primary/secondary DNS for acad.bg domain:

ns6-a.acad.bg IN AAAA 2001:4b58:acad::3

ns6-b.acad.bg IN AAAA 2001:4b58:acad::9
Several WWW sites:

http://netmon.acad.bg (network monitoring tools portal)

http://bis-21pp.acad.bg (site of the Bulgarian IST Centre of
Competence in 21 Century – BIS-21++)

http://webmail.acad.bg (web access to local mailboxes)

ISTF’s international IPv6 traffic volume



ISTF’s international IPv6 traffic
December 2005 amounted to:

170 MB transmitted to GÉANT2

470 MB received from GÉANT2
volume
for
When compared to ISTF’s international IPv4 traffic,
it accounts for:

~ 0,0027 % of the total egress traffic

~ 0.0087 % of the total ingress traffic
IPv6 traffic is rather low, but … what is the IPv4/IPv6
traffic ratio in other NRENs !!??

14
IPv6 deployment in ISTF’s network

Setbacks:

Still not enough resources for end-user deployment at
other places
No enough qualified staff
No sufficient motivation to deploy IPv6 ( not found The
IPv6 killer application … yet )


While we are working on the first two, we can hardly
influence the lack of The ‘Killer Application’

IPv6 deployment in ISTF’s network

Little Tricks !

In order to stimulate IPv6 deployment in the
Regional Centres we announced and provide
unlimited IPv6 traffic bandwidth to the Regional
Centres (whereas IPv4 traffic bandwidth is limited
according to the respective contracts with the RC)

16
The future

Further deployment at the national backbone is planned,
eventually to cover it completely

Making IPv6 available to a larger portion of the end-users,
especially where the protocol shows its strengths (e.g. the
integrated security)

Establishment of IPv6 peerings with Bulgarian ISPs is foreseen,
possibly marking the beginning of a true nation-wide IPv6
backbone

The progress depends very much on the available hardware and
software, which is still inadequate – have a router to spare? ;-)
