Overview
Outlines BGP flowspec concepts, deployment models, configuration methods, verification procedures, advanced redirect scenarios, traffic filtering actions, IPv6 packet length support, and flow-tag propagation for comprehensive traffic control and security in network infrastructures.
This chapter details BGP Flowspec, a routing feature enabling dynamic traffic filtering, policing, and automated threat mitigation, especially against DDoS attacks. It covers configuring client and server roles, verifying operations, and implementing advanced traffic redirection from global VRF to L3VPN or segment routing policies.
BGP flowspec
Introduces BGP flowspec, describing the client-server controller models, feature restrictions, step-by-step configuration for clients and servers, and comprehensive verification procedures covering running configurations, flow details, and operational status on clients
BGP flowspec redirect from global VRF to L3VPN and segment routing policy
Explains BGP flowspec redirect operations from global VRF to L3VPN and segment routing policies, emphasizing traffic redirection mechanisms and integration with advanced network architectures.
How BGP flowspec redirect from global VRF to L3VPN and segment routing policy works
Details the operational workflow of BGP flowspec redirects from global VRF to L3VPN and segment routing policies, illustrating procedural logic and packet-handling processes in complex routing environments.
Configure BGP flowspec redirect from global VRF
Provides instructions for configuring BGP flowspec redirect from global VRF, guiding users through command procedures to enable dynamic traffic redirection within multi-VRF architectures.
Traffic filtering actions: what you need to know about controlling traffic with BGP flowspec
Describes traffic filtering actions available with BGP flowspec, outlining methods and considerations for controlling, classifying, and managing network traffic using advanced flow specifications.
BGP flowspec IPv6 packet length
Introduces BGP flowspec IPv6 packet length functionality and provides instructions for enabling IPv6 packet length support, enhancing traffic filtering capabilities in IPv6 environments.
Flow-tag propagations
Explains flow-tag propagation concepts, including source and destination-based flow tag principles, to support advanced identification and handling of traffic flows across the network.
