/*
 * The Zebra Protocol is the protocol used between the Zebra routing daemon and
 * other protocol daemons (ones for BGP, OSPF, etc.) within the Zebra, Quagga,
 * and FRRouting open-source routing suites.
 * Zebra itself (https://www.gnu.org/software/zebra) is discontinued,
 * and its successor is Quagga (http://www.nongnu.org/quagga).
 * The successor to Quagga is FRRouting (https://frrouting.org/).
 *
 * All three use the "Zebra Protocol" (or ZAPI), but starting with Quagga v0.99
 * there are different versions, with different header formats and more
 * commands/types.
 *
 * http://www.nongnu.org/quagga/docs/docs-info.html#Zebra-Protocol
 * http://docs.frrouting.org/projects/dev-guide/en/latest/zebra.html
 *
 * Version 0 (implicit): Zebra, Quagga up to version 0.98
 * Version 1: Quagga 0.99.3 through 0.99.20
 * Version 2: Quagga 0.99.21 though 0.99.23
 * Version 3: Quagga 0.99.24 and later
 * Version 4: FRRouting 2.0 through 3.0.3
 * Version 5: FRRouting 4.0 though 5.0.1
 * Version 6: FRRouting 6.0 and later
 *
 * FRRouting versions 4 and 5 have partially incompatible commands.
 * This dissector uses the commands of FRRRouting version 5.
 * FRRouting versions 6 and 7 have partially incompatible commands.
 * This dissector uses the commands of FRRRouting version 7.
