Configuring gated
Configuring the RIP Protocol
yes (or on) tells gated to enable the RIP protocol at this node and
process RIP packets coming in from other nodes. no (or off) tells gated
to disable the RIP protocol at this node. If gated finds fewer than two
network interfaces, the node only listens to RIP information. If gated
finds two or more network interfaces, the node both listens to and
broadcasts or multicasts RIP information. If you do not specify a RIP line
in your configuration file, rip on is assumed.
broadcast specifies that RIP packets are always generated. If the RIP
protocol is enabled and more than one interface is specified, broadcast
is assumed. Specifying broadcast with only one interface is useful only
when propagating static routes or routes learned from other protocols.
nobroadcast specifies that RIP packets are sent only to routers listed in
the sourcegateways clause. If the RIP protocol is enabled, but only one
interface is specified, nobroadcast is assumed.
nocheckzero specifies that theRIP protocol should not check to see if the
reserved fields in the RIP packets are zero. In RIP version 1 (as described
in RFC 1058), certain reserved fields should be zeroed out; however, this
may vary in RIP implementations.
preference determines the order of routes from other protocols to the
same destination in the routing table. gated allows one route to a
destination per protocol for each autonomous system. In the case of
multiple routes, the route used is determined by the value of
preference.
Default: 100
Range: 0 (most preferred) - 255 (least preferred)
defaultmetric is the default metric used when propagating routes
learned from other protocols.
Default: 16
Range: 1 - 16
query authentication [none|[[simple|md5] password ]] specifies
the authentication, if any, that is required for query packets that do not
originate from routers. If authentication consisting of only a password is
required, specify simple password or just password . If the required
authentication consists of a key that was created with the MD5
algorithm, specify md5. The default is none.
interface is specified as one of the following (in order of precedence): an
