     RIP(8)                                                     RIP(8)

     NAME
          rip - routing information protocol

     SYNOPSIS
          ip/rip [-2] [-b] [-d] [-n] [ -x mntpt ] [ net ...  ] &

     DESCRIPTION
          Rip implements the Internet RIP routing protocol described
          by RFC1058 and RFC2453.  It watches the network and makes
          appropriate changes to the machine's Internet routing table
          (see iproute in ip(3)), based on routing packets broadcast
          by gateways on the network.  Rip is only used when a single
          default gateway is inadequate, typically because a machine
          sits on a network directly connected to several others, hav-
          ing no common gateway or router.  On networks where there is
          just one gateway, it is usually simpler and more efficient
          to configure that statically using ndb(6) or dynamically
          using DHCP/BOOTP, rather than running rip.

          Rip serves the network on mntpt (default: /net).  When it
          starts, rip learns its own interfaces and directly attached
          networks by reading mntpt/ipifc, and notes any routes cur-
          rently in mntpt/iproute.

          By default, rip neither broadcasts routes nor replies to
          requests for its route table.  If the -b option is given,
          rip periodically broadcasts changes to its routing table to
          each of its interfaces.  If at least one explicit net
          address is given, the broadcasts are restricted to just the
          interfaces listed (and -b is implied).

          The -d option causes routed to record changes it makes to
          the routing tables.  This can be helpful when locating mis-
          leading announcements from rogue gateways.  A second -d will
          include detailed information about every packet.  The -n
          option tells rip not to change the local routing table, but
          only say what changes it would have made.

          Rip understands both version1 and version 2 of the protocol,
          and interprets updates from gateways appropriately.  By
          default, it transmits updates using version 1; if the -2
          option is given, it uses version 2 instead, which is prefer-
          able when the network has subnets.
