Macro names must start with a letter, digit, or underscore, and may contain any of those characters. Macro names may not be reserved words (for example, .Ic cost ) . Macros are not expanded inside quotes. .Pp For example: .Bd -literal -offset indent hi="2" interface em0 { cost $hi } .Ed .Sh GLOBAL CONFIGURATION Global settings concerns the main behaviour of the daemon. .Pp .Bl -tag -width Ds -compact .It Ic fib-priority Ar prio Set the routing priority to .Ar prio . The default is 40. .Pp .It Xo .Ic fib-update .Pq Ic yes Ns | Ns Ic no .Xc If set to .Ic no , do not update the Forwarding Information Base, a.k.a. the kernel routing table. The default is .Ic yes . .Pp .It Ic rdomain Ar tableid Specifies the routing table .Xr ripd 8 should modify. Table 0 is the default table. .Pp .It Xo .Op Ic no .Ic redistribute .Sm off .Po Ic static Ns | Ns Ic connected Ns | Ns .Ic default Pc .Sm on .Xc .It Xo .Op Ic no .Ic redistribute Ar prefix .Xc .It Xo .Op Ic no .Ic redistribute rtlabel Ar label .Xc If set to .Ic connected , routes to directly attached networks will be announced over RIP. If set to .Ic static , static routes will be announced over RIP. If set to .Ic default , a default route pointing to this router will be announced over RIP. It is possible to specify a network range with .Ar prefix ; networks need to be part of that range to be redistributed. Additionally it is possible to redistribute based on route labels using the .Ic rtlabel keyword. By default no additional routes will be announced over RIP. .Pp .Ic redistribute statements are evaluated in sequential order, from first to last. The first matching rule decides if a route should be redistributed or not. Matching rules starting with .Ic no will force the route to be not announced. .Pp .It Xo .Ic split-horizon .Sm off .Po Ic simple Ns | Ns Ic poisoned Ns | Ns .Ic none Pc .Sm on .Xc If set to .Ic simple , do not redistribute routes to the interface from which they were learned. If set to .Ic poisoned , redistribute routes to the interface from which they were learned, by forcing the metric to infinity. Both these behaviours can resolve routing loops when a router goes down. The default is .Ic poisoned . .Pp .It Xo .Ic triggered-updates .Pq Ic yes Ns | Ns Ic no .Xc Immediately trigger responses when a route changes. The default is .Ic no . .El .Sh INTERFACES Each interface can have several parameters configured individually, otherwise they are inherited. .Bd -literal -offset indent interface em0 { cost 9 auth-type none } interface ix1 .Ed .Pp Interface-specific parameters are listed below. .Bl -tag -width Ds .It Ic auth-key Ar key Set the authentication key for .Ic simple authentication. Up to 16 characters can be specified. .It Ic auth-md Ar key-id key Set the authentication .Ar key-id and .Ar key for .Ic crypt authentication. The valid range for .Ar key-id is 0\-255. Up to 16 characters can be specified for .Ar key . Multiple keys may be specified. .It Ic auth-md-keyid Ar key-id Configure the .Ar key-id to use for .Ic crypt authentication. The valid range for .Ar key-id is 0\-255. The default key-id is 1. .It Xo .Ic auth-type .Po Ic none Ns | Ns .Ic simple Ns | Ns Ic crypt Pc .Xc Set the authentication type. The default is .Ic none . Simple authentication uses a plaintext password, up to 16 characters. Crypt authentication uses an MD5 hash. .It Ic cost Ar number Cost of the network connected through this interface. Values must be between 1 and 16, inclusive. .It Ic demote Ar group Increase the .Xr carp 4 demotion counter by 1 on the given interface group, usually .Ar carp , when the interface state is going down. The demotion counter will be decreased when the interface state is active again. .It Ic passive Prevent transmission and reception of RIP packets on this interface. .El .Sh FILES .Bl -tag -width /etc/examples/ripd.conf -compact .It Pa /etc/ripd.conf .Xr ripd 8 configuration file. .It Pa /etc/examples/ripd.conf Example configuration file. .El .Sh SEE ALSO .Xr rc.conf.local 8 , .Xr ripctl 8 , .Xr ripd 8 .Sh HISTORY The .Nm file format first appeared in .Ox 4.1 .
