BGP Routing Implementation

Project Overview

This project implements BGP (Border Gateway Protocol) routing in a Mininet environment based on a specified network topology consisting of three Autonomous Systems (AS).

Network Topology

Screenshot 2024-10-24 155734

The network consists of three Autonomous Systems interconnected through eBGP, with internal routers using iBGP and OSPF.

Autonomous System Details

AS 100

  • Routers: R11, R12, R13, R14
  • Devices:
    • Client: C11
    • Switch: S11 (connects C11 to R11)
  • Internal Structure:
    • Forms a full mesh topology between all routers
    • R14 serves as the edge router for eBGP connection
  • Connections:
    • R14 connects to R22 (AS200) via eBGP
    • All internal routers connected via iBGP
    • OSPF running internally

AS 200

  • Routers: R21, R22, R23, R24
  • Devices:
    • Client: C22
    • Switch: S2 (connects C22 to R21)
  • Internal Structure:
    • Forms a full mesh topology between all routers
    • R22 and R23 serve as edge routers
  • Connections:
    • R22 connects to R14 (AS100) via eBGP
    • R23 connects to R34 (AS300) via eBGP
    • All internal routers connected via iBGP
    • OSPF running internally

AS 300

  • Routers: R31, R32, R33, R34
  • Devices:
    • Client: C33
    • Switch: S33 (connects C33 to R33)
  • Internal Structure:
    • Forms a full mesh topology between all routers
    • R34 serves as the edge router
  • Connections:
    • R34 connects to R23 (AS200) via eBGP
    • All internal routers connected via iBGP
    • OSPF running internally

Protocol Implementation

  1. External BGP (eBGP):

    • Connection between AS100 and AS200: R14 - R22
    • Connection between AS200 and AS300: R23 - R34
    • Shown as red dashed lines in the topology

  2. Internal BGP (iBGP):

    • Full mesh iBGP connections within each AS
    • Shown as black dashed lines in the topology

  3. OSPF:

    • Running within each AS
    • Used for internal routing

Client Connectivity

  • C11: Connected to AS100 through switch S11 and router R11
  • C22: Connected to AS200 through switch S2 and router R21
  • C33: Connected to AS300 through switch S33 and router R33

Project Requirements

  1. Implement the complete network topology in Mininet environment
  2. Configure all routing protocols:
    • eBGP for inter-AS communication
    • iBGP for intra-AS routing
    • OSPF for internal routing within each AS
  3. Ensure proper connectivity between all clients

Development Status

🚧 Note: This repository is currently under development.

To-Do List

  • Network topology implementation
  • OSPF configuration for each AS
  • iBGP mesh configuration within AS
  • eBGP peering configuration
  • Client connectivity setup
  • Testing and validation
  • Documentation completion
