Configuring Active RIP
The following section assumes that you have read the sections on active and
passive RIP in the Remote Annex Administrator’s Guide for UNIX. Active RIP is
enabled by default. Once active RIP is enabled, both passive and active RIP run on
all operational interfaces.
Defining Routes
Once you have enabled active RIP, you do not need to define the default and static
routes in most configurations. The network nodes learn about the routes to each
other and to other networks through RIP updates they exchange, provided that all
of the following conditions are met:
• For subnetted networks, the
rip_sub_advertise
parameter on the Remote
Annex is set to Y (the default).
• You have configured subnet masks correctly.
• The gateway is configured to handle the same type of RIP updates.
Although the routes required for passive RIP need not be defined after you enable
active RIP, you may want to define a default route and one or more static routes
for other purposes. For example, a default router can act as a bottleneck through
which all traffic to and from a network must pass. You can also use static routes to
reach routers that are not running active RIP.
To define default and static routes that remain across Annex boots, enter them in
the config.annex file. You can define routes anywhere in the configuration file, but
routes not defined in an “annex...end” or “subnet...end” block are discarded and
not cached if their interfaces are not operational when the Annex is booted.
Typically, the Ethernet interface is operational immediately, but SLIP and PPP
interfaces may take longer to come up.
Configuring the Annex to Advertise RIP Updates
By default, active RIP sends RIP Version 2 updates to the IP broadcast address, so
that both RIP 1 and RIP 2 systems can receive them. This assumes that the
rip_send_version parameter is set to compatibility, which is the default. It also
assumes that the routers on your network accept both RIP 1 and RIP 2 updates.
