Bolivia hosts South America Technical Training Workshop
The event, to be held on November 2th to 4th, is part of the ALICE2 project Work Package 8, WP8, which aims to achieve the inclusion and connection to RedCLARA of Honduras, Nicaragua, Bolivia, Paraguay and Cuba, countries that are not yet part of the initiative.
As part of Work Package 8, WP8 of the project Latin America Interconnected with Europe 2, (América Latina Interconectada con Europa, ALICE2), on November 2 th to 4th, the Institute of Applied Electronic of the San Andres Mayor University (Universidad Mayor de San Andrés, UMSA) in La Paz Bolivia, will host the South America Technical Training Workshop.
This activity is the last of two workshops devoted to strengthen recent National Research and Education Networks (NRENs).
The coordination of the event in Bolivia is headed by the Executive Director of the Agency for the Development of Information Society in Bolivia, ADSIB, Jorge Alejandro Patino, in the administrative area, and the consultant and teacher of the UMSA, Roberto Zambrana in the technical side; and counts with the participation of Jose Contreras and Javier Tórrez of the Latin American Networking School Foundation, Escuela Latinoamericana de Redes, EslaRed, and Jose Dominguez from the National Science Resources Center, NSRC, as instructors.
After the success of ALICE, in the creation of CLARA and in the connection of the different National Research and Education Networks, ALICE2 has continue the effort, achieving the inclusion and connection to RedCLARA of Honduras, Nicaragua, Bolivia, Paraguay and Cuba, countries that are not yet part of the initiative.
PROGRAM
1. Introduction to Internet routing
Objectives:
- Identify the different topologies in the Internet.
- Distinguish between transit and exchange (peering).
- Understand the different types of interchange points.
- Name the different categories of ISPs.
- Understand the concepts of: Routing vs. Forwarding, Roads, Routes, Policy.
- Define terms such as neighbors, announcements, peers, packet flow, etc.
- Distinguish between IGPs and EGPs.
2. Concepts of Resistant Network Design
- Explain the concept of a well-designed network, modular functionality.
- Describe a good design for a resilient network with two switches in the core, edge routers with redundant connections and access routers.
- Physically separate networks for different traffic types.
- Stressing platform requirements, infrastructure, redundant cable routes.
- Capabilities to resilience, scalability and ease of maintenance.
- Stressing the need for non-Lockable switches, HSRP / VRRP, and other features.
3. Border Gateway Protocol (BGP)
This presentation takes a full day, including exercises.
Objectives:
- Explain the need for an EGP (exchange traffic / routes to other networks, the cost of transit versus peering. Inability to use static routes or IGP.
- Set Autonomous System (AS).
- Describe the key features of BGP4 ( "peering" point to point, TCP, incremental updates, route attributes, eBGP and iBGP).
- List important attributes: AS Path, Next Hop, Local Preference, MED, Communities.
- Describe the typical path selection based on AS Path, and emphasize the use of "prepending" to influence the selection of the way up.
- Explain the recursive search Attribute "Next Hop".
- Using the list selection rules of BGP routes.
- Read the table of "distance" to know what protocol wins.
- Establishing an exchange of BGP session with a supplier.
- Establish a brainstorming session with a BGP Peer.
- Establish "peers" iBGP.
- Use filters "AS Path and prefix list.
- Configure iBGP neighbors.
- Exercise of basic BGP.
- Exercise of Filtering Routes.
