• The 6NET-NRN (6680:10) community identifies prefixes that belong directlyto partner NREN.• The 6NET-OTHER (6680:99) community identifies all other prefixes thatNREN advertise to 6NET.Our autonomous system 2852 may therefore advertise prefixes identified by the6NET-NRN community to all other autonomous systems, with which we peer;however, all prefixes identified with the 6NET-OTHER community always haveto be filtered.So far, our AS 2852 has agreed on IPv6 peering with the following autonomoussystems (in all cases with the use of a tunnel):1. AS 6680, 6NET: connection to 6NET, this link should be transferred to thenative circuit STM-1 in early 2003.2. AS 2200, Renater: this connection to the GTPv6 network is used for testingwithin TF-NGN 4 .3. AS 1299, Telia International Carrier: quality transit connectivity.4. AS 25336, 6COM: the first national IPv6 peering in the Czech Republic.Our objective is to maintain the number of links to other autonomous systemsat a reasonable level, either in the form of native circuits or high-quality tunnelswith low delay. This way, we want to avoid problems that have completely degradedthe 6Bone experimental network.5.2.6 IPv6 Network MonitoringAt present, connectivity and basic IPv6 services are monitored from the standardmonitoring system saint.cesnet.cz. The monitoring is carried out with theuse of modified modules supplied together with the Nagios 5 monitoring software,or newly developed modules. This system is linked to the IPv6 networkdirectly at the second layer. The following areas are monitored:• Availability of backbone routers,• Availability of border routers for peering neighbours,• Status of significant services within IPv6,• Router information in BGP protocol.We monitor the network load with the use of the GTDMS 6 software. For the mapof the current load, see http://www.cesnet.cz/provoz/zatizeni6/.4http://www.dante.net/tf-ngn/5http://www.nagios.org/6http://www.cesnet.cz/doc/zprava2001/sled.html68 High-speed National Research Network and its New Applications 2002
5.2.7 Connecting End Site NetworksIn order to increase the number of IPv6 subscribers, it is necessary to supportthis network protocol in the local network routers of linked institutions.Subscribers only need to activate IPv6 in their operating system, and all thenecessary configuration details (IPv6 address, mask and default gateway) willbe acquired through stateless autoconfiguration.IPv6 is currently available, to some extent, in the local networks of all connectednodes. Due to the considerable variety of router hardware and software inlocal networks and the understandable caution of local network administrators,IPv6 is usually routed with the use of a separate router that does not route IPv4.It is connected either directly, or through virtual LANs, according to the IEEE802.1Q standard.For all the important details concerning the IPv6 backbone networks and internationallinks, see Figure 5.2.Telia, AS 12992001:6c0:800:2002::3/64213.248.74.2026NET, AS66802001:718:0:b000::2/6462.40.98.1422001:6c0:800:2002::/642001:718:0:b000::/642001:660:1102:400a::/64GÉANT, AS22002001:660:1102:400a::1/64193.51.207.243Ústí nad Labem2001:718::9195.113.144.322001:718:9:4000::/642001:718:0:11::/646COM, AS 253362001:718:0:4000::2/6462.24.64.272001:718:0:2::/642001:718:0:3::/64R1-PRG2001:718::8195.113.144.1giga0.cesnet.cz2001:718::1195.113.156.183Plzeň2001:718::5195.113.157.36Liberec2001:718::3195.113.156.2132001:718:0:4::/642001:718:0:9::/642001:718:0:5::/64Hradec Králové2001:718::6195.113.144.812001:718:0:1::/64České Budějovice2001:718::4195.113.157.522001:718:0:6::/642001:718:0:7::/642001:718:0:8::/64Ostrava2001:718::7195.113.157.5Brno2001:718::2193.84.209.2Figure 5.2: IPv6 backbone of CESNET2 – detailed viewHigh-speed National Research Network and its New Applications 200269
