 FRRouting implements the routing protocols commonly used in the
 internet and private networks to exchange information between routers.
 Both IP and IPv6 are supported, as are BGP, OSPFv2, OSPFv3, IS-IS, BABEL,
 EIGRP, RIP, RIPng, LDP, BFD, PIM, VRRP, PBR, and NHRP.
 .
 These protocols are used to turn your system into a dynamic router,
 exchanging information about available connections with other routers
 in a standards-compliant way. The actual packet forwarding
 functionality is provided by the OS kernel.
 .
 FRRouting is a fork of Quagga with an open community model. The main
 git lives on https://github.com/frrouting/frr.git and the project name
 is commonly abbreviated as "FRR."
