This guide briefly describes the Border Gateway Protocol 4+ (BGP4+) in general terms and how to configure a variety of IPv6 routing scenarios using BGP4+ on AlliedWare Plus™. It is intended for audiences with a good understanding of network routing protocols and device configuration.

The discussion begins with an overview of the BGP4+ protocol and related RFCs, how it operates, and where it is normally implemented. This is followed by a basic set-up guide which also outlines inter-operation with other vendors, basic and advanced set-up instructions for BGP peering, and how to verify BGP settings using appropriate AlliedWare Plus show commands. This section rounds off with a description of BGP and BGP4+ terms used throughout the guide. The guide then provides a variety of BGP4+ configuration scenarios. Each scenario includes a simple network diagram, step-by-step configuration instructions, and examples of command output verifying the configuration.

The configuration examples are grouped into the following areas:

  • BGP4+ Basic setup
  • Redistribution
  • Route Filtering
  • Route Aggregation
  • Path Control
  • Load Sharing Examples
  • Session Management Options
  • Comparison of BGP Session Reset Methods
