GEANT-TF, Rome, 31/03/2003
Portugal
PORTUGAL
+ Small Country
+ 10 million people
+ Lisbon: 2 million
+ Oporto: 1 million
+ Few Telcos = Circuits very expensive!
+ But GSM did great!
+ FCCN manages Research Network
+ STM-4 Connection to Geant (in Madrid)
+ One IXP, Gigapix, managed by FCCN
+ ccTLD .pt also managed by FCCN
History – 6bone
History - Linux
Addressing
• 2001:690::/32 for RCTS2
• 2001:07f8:000a::/48 for GIGAPIX (IXP)
Addressing Plan
• /48s for each Access Point. (Universities, Labs, …)
• /56s for each of the 12.000 schools and libraries
connected to the Internet@School Network
• /126 for point-to-point backbone links
• We reserved some bits for future use
• We did preemptive allocations to each access
(94 /48s), can be seen on RIPEdb.
BGP4+
• Over 12 Tunnels and Native (RNP &
Gigapix)
• Getting around 430 prefixes (3FFE:: and
2001::) from peers
• Filtering (using prefix-lists)

External Routing
• Access to
prefixes through
• Access to
: difficult, due to
topology: high roundtrips
• M40 will connect to GEANT, one C3640 is
connecting to RNP natively (Brazil)
Cantino Link
• Dual-Stack (IPv4/IPv6)
• 2Mbps Circuit (E1)
• First direct connection between Europe and
South America (Lisbon-Rio) for R&D
purposes
• RNP has several ASes, and already got a
2001:: prefix from ARIN
• Traffic Testing over IPv6 using MGEN6
Internal Routing
• Current IGP: IS-IS
• Running on 4 Junipers (3xM10 and 1xM40)
and around a dozen Ciscos (1x12xxx,
3x75xx, 3x36xx, 6x26xx, …)
• OSPFv3, in the future (3Q 2003?)
• The network is basically «two stars», with
its centers located in Lisbon and Oporto.
Topology
• Core (Lisbon-Oporto) running on
GigEthernet over a Lambda, and using a
POS STM-1 as a backup.
• Two Tunnel Gateways (in Lisbon and
Oporto).
• Members joining the IPv6 network establish
a tunnel to both tunnel gateways.
Keepalives are configured on all ends.

Topology - Known Problems #1
• Our Cisco 72xx (Access Routers) are not
running an IOS version with IPv6 support:
Main reason is T family not being accepted
as best solution in terms of stability
Topology - Known Problems #2
• Some Academic Network members don’t
have support contracts with some Vendors
(ex:Cisco).
This way they can’t get newer/improved
IOS version with IPv6 support
Testbed
• ~50% of our IPv6 routers are
part of the TESTBED
• Not easy to get memory
upgrades for Cisco routers!!!
(but already got some!)
• Old PCs (i586/i686) reassigned
to IPv6 testing are running
Linux (Redhat)
Testing
• Equipments: Cisco, 6WIND, PC/Zebra
• Native connections over IPv6:

Transition Mechanisms
• We are providing a 6to4 gateway to the
world (2002:C188:2F6::1).
• We will focus on NAT-PT.
• Battery of tests being written (delayed due
to backbone upgrade).
Gigapix
• 18 Members
• IPv6: Started March 2003, with 3 members
peering natively.
Gigapix
• 3 more LIRs in Portugal already have a
RIPE allocation (KPN, ONI and NFSI)
• The first two are already on the IXP, but
only on IPv4.
• NFSI is planning to connect soon (both on
IPv4 and IPv6)
Work to do!
