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.
