Configuring a RIP Interface for Dial-Optimized Routing
Dial-optimized routing is a method for reducing costs on dialed lines. Under
dial-optimized routing, RIP exchanges routing information on the interface only
when the router or a peer has activated the connection for a data transmission. RIP
does not initiate a connection on a dialed line solely for the purpose of issuing a
routing update.
For information about enabling dial-optimized routing, see Configuring Dial
Services.
After you enable dial-optimized routing, you can set RIP timers to control the way
RIP generates updates on interfaces to dialed lines. Setting RIP timers allows you
to specify the following:
• The frequency at which RIP broadcasts full RIP updates on the interface
• The timeout period that RIP waits before considering a network unreachable
• The holddown period that unreachable routes are retained in the routing table
and advertised
Specifying the Full Update Interval
By default, RIP generates a full update every 30 seconds on each interface
configured with RIP. If you enabled dial-optimized routing on this interface, the
default is 1 hour.
You can use the BCC or Site Manager to specify an update interval for the
interface. If you change the value of the update interval from the default value,
you should also change the timeout period and the holddown period to a value
equal to three times the update interval (see “
Specifying a Timeout Period” on
page 5-20 and “Specifying a Holddown Period” on page 5-21).
