2002 - cesnet

Within the informative part, we required the presentation of the function implementationand other possible configurations, which can be offered by therouters in question:• Presentation of features and characteristics that may require the use ofexperimental versions of operating system or which are not fully standardized,• Verification of Ethernet over MPLS,• Support of multicast in VPN,• IPv6,• Possibility of connection to CESNET2 IPv6 backbone,• Verification of basic functions and routing protocols (RIP6, BGPv6, IC-MPv6,…)The tested devices were attached to the backbone network. According to theresults of the tender, we selected the Cisco 7206 routers with the NPE-G1 processorfor small nodes, and Cisco 7609 for medium and large nodes. The offeredOSR 7609 configurations fulfilled the requirements; however, it turned out thatthe manufacturer is planning some radical technical innovations during the firsthalf of the year 2003 and it makes no sense for us to purchase non-perspectivedevices. These are the following components:• GE-WAN modules, Type I – to be replaced with modules of Type II, with thesupport of ATOM (Any Transport Over MPLS),• Supervizor2/MSFC2 – a new type, Supervizor3/MSFC3, will soon be available,with an integrated switch matrix and, mainly, with hardware supportfor IPv6 routing.According to our negotiations with the supplier, the entire supply was dividedinto two stages. Within first stage (to be completed before the end of 2002), wewill purchase the 7206 routers with NPE-G1 for GigaPoP Ústí nad Labem andZlín, as well as OSR 7609 routers without the modules mentioned above. In addition,we will borrow the modules of the current design for a necessary periodof time. As soon as modules of the new generation are introduced, we will purchasethem and upgrade the device.We expect new PE routers to be gradually put into operation in January andFebruary 2003. PE routers in the backbone network will provide the basic functions:MPLS VPN, support of QoS, multicast, ATOM (EoMPLS), IPv6 in IOS, possibilityof configuring input/output filters and traffic shaping/CAR at all links tothe backbone network, together with NetFlow export version 5 and 7.The P and PE routers will be connected through two GE interfaces with loadballancing. In the large GigaPoPs (Prague and Brno), we will make use of 2 × POSSTM-16 in order to reach sufficient capacity, also with load ballancing.High-speed National Research Network and its New Applications 200227
