Border Gateway Protocol (BGP) Configuration

Objective

This focuses on implementing and verifying Border Gateway Protocol (BGP) routing on network routers.

Overview

Configure BGP on multiple routers across different Autonomous Systems (AS).
Establish BGP neighbor relationships.
Advertise and verify network routes using BGP.
Troubleshoot BGP connectivity issues.

Network Topology

Router A (AS 100) ↔ Router B (AS 200)
Router B (AS 200) ↔ Router C (AS 300)
Router C (AS 300) ↔ Router D (AS 400)

Configuration Steps

Set Up the Lab Environment
- Connect routers according to the given topology.
- Assign IP addresses to router interfaces.
Configure BGP on Each Router
- Enter BGP mode: router bgp [AS number]
- Set up BGP neighbors: neighbor [IP] remote-as [AS]
Advertise Networks
- Use network [network IP] mask [subnet mask].
Verify BGP Configuration
- Check neighbor status: show ip bgp summary
- View BGP routes: show ip bgp
Test and Troubleshoot
- Verify connectivity with ping.
- Debug issues using show ip bgp neighbors and show ip route.

Tools Required

Cisco Packet Tracer
