IPv6: 

IPv6 @RCTS2 cfriacas@fccn.pt 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 Portugal

Addressing: 

Addressing 2001:690::/32 for RCTS2 2001:07f8:000a::/48 for GIGAPIX (IXP)

Addressing Plan: 

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+: 

BGP4+ Over 12 Tunnels and Native (RNP & Gigapix) Getting around 430 prefixes (3FFE:: and 2001::) from peers Filtering (using prefix-lists)

BGP4+ Map: 

BGP4+ Map

External Routing: 

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: 

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: 

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: 

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: 

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: 

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: 

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: 

Testing Equipments: Cisco, 6WIND, PC/Zebra Native connections over IPv6: ATM (E3 and STM-1) Giga/Fast/Ethernet Serial/V.35 Packet Over Sonet E1 HSSI

Transition Mechanisms: 

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: 

Gigapix 18 Members IPv6: Started March 2003, with 3 members peering natively.

Gigapix: 

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)
