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, having
no common gateway or router. On networks where there is just one gate‐
way, it is usually simpler and more efficient to configure that stati‐
cally 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 currently 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 broad‐
casts 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 misleading 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 inter‐
prets 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 preferable when the network has subnets.
