## What it is
FRRouting (FRR) is a free, open-source IP routing protocol suite for Linux and Unix platforms, descended from Quagga. It implements and manages IPv4/IPv6 routing protocols including BGP, OSPF, RIP, IS-IS, PIM, LDP, BFD, Babel, PBR, VRRP, and more, integrating with the native kernel networking stack.

## Use cases
- run a BGP route reflector or Internet peering router on Linux
- turn a Linux box into an OSPF or IS-IS core router
- advertise network services and anycast prefixes with BGP
- connect hosts, VMs, and containers to the network with dynamic routing
- implement VRRP failover for LAN gateways
- set up multicast routing with PIM and MSDP
- build MPLS/EVPN fabrics with LDP and BGP EVPN
- replace commercial router software with an open-source routing stack

## When to choose
- you need a full-featured, actively maintained open-source routing suite on Linux/BSD
- you want BGP, OSPF, IS-IS, PIM, and MPLS support in one package
- you need RFC-compliant routing daemons with YANG-based centralized configuration
- you are building ISP, datacenter, or cloud network infrastructure on commodity hardware

## When to avoid
- you only need simple static routing, which the OS can handle natively
- you need EIGRP or NHRP as first-class, production-grade features (still alpha)
- you require a GUI-driven network management platform rather than a CLI/config-based daemon suite
- you need routing on non-Unix platforms like Windows
