+      FRRouting (FRR) is a free and open source Internet routing protocol suite
+      for Linux and Unix platforms. It implements BGP, OSPF, RIP, IS-IS, PIM,
+      LDP, BFD, Babel, PBR, OpenFabric and VRRP, with alpha support for EIGRP
+      and NHRP.
+
+      FRR’s seamless integration with native Linux/Unix IP networking stacks
+      makes it a general purpose routing stack applicable to a wide variety of
+      use cases including connecting hosts/VMs/containers to the network,
+      advertising network services, LAN switching and routing, Internet access
+      routers, and Internet peering.
+
+      FRR has its roots in the Quagga project. In fact, it was started by many
+      long-time Quagga developers who combined their efforts to improve on
+      Quagga’s well-established foundation in order to create the best routing
+      protocol stack available. We invite you to participate in the FRRouting
+      community and help shape the future of networking.
+
+      Join the ranks of network architects using FRR for ISPs, SaaS
+      infrastructure, web 2.0 businesses, hyperscale services, and Fortune 500
+      private clouds.
