## What it is
ExaBGP is a Python-based BGP protocol implementation that lets network engineers control and interact with BGP sessions through a JSON API and external scripts. Unlike traditional BGP daemons, it does not manipulate the FIB, focusing instead on protocol flexibility for automation and monitoring.

## Use cases
- inject and withdraw BGP routes from scripts for traffic engineering
- mitigate DDoS attacks by announcing blackhole routes or FlowSpec filters
- build cross-datacenter failover by migrating service IPs via BGP
- collect network topology data using BGP-LS or Add-Path
- automate anycast network control
- run a BGP looking glass or route collector for monitoring

## When to choose
- you need to script or programmatically control BGP announcements
- you want a lightweight BGP speaker without FIB manipulation
- you need broad address family support like FlowSpec, EVPN, BGP-LS, or SRv6 in a test lab
- you are building DDoS mitigation or anycast automation

## When to avoid
- you need a production router that installs routes into the kernel FIB (use FRRouting or BIRD)
- you need maximum performance, in which case the Go successor Ze is recommended
- you want a GUI or turnkey routing solution rather than a scriptable toolkit
