define Package/frr/description
  FRRouting is free software that implements and manages various IPv4 and IPv6
  routing protocols.

  Currently FRRouting supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, RIPng,
  IS-IS, PIM-SM/MSDP, LDP, VRRP and Babel as well as very early support for EIGRP and
  NHRP.
