Dial-on-Demand Implementation Notes
114062 Rev. A 4-5
Dial Optimized Routing
Dial optimized routing lets you exchange IP RIP and IPX RIP/SAP routing
updates only when a connection is active for data transmission. By limiting when
the router can send updates, dial optimized routing reduces unnecessary
connections and line costs.
For each dial-on-demand circuit, you have the choice of enabling dial optimized
routing. If you enable dial optimized routing, the router establishes a demand
connection only for outbound data packets or through requests from the protocol.
The presence of IP RIP and IPX RIP/SAP packets alone will not trigger a dial
connection. If you disable dial optimized routing, any packets can initiate demand
connections.
Version 11.0 supports dial optimized routing only for IP and IPX. For all other
protocols, the router activates a demand connection for any type of routing packet,
regardless of dial optimized routing. To avoid this problem, you can configure
traffic filters that prevent specific types of packets from activating a connection.
Refer to Configuring Traffic Filters and Protocol Prioritization for information
about configuring filters.
What Happens When You Enable Dial Optimized Routing
When there is data to send, the router activates a demand connection. The router
software then alerts the IP and IPX protocols that a connection is active and they
can broadcast routing updates. The protocols can also send triggered updates, if
any occur while the connection is up.
The connection remains active for a user-defined Minimum Duration Time. As the
name indicates, this timer specifies the minimum amount of time the connection is
active. This timer must be set long enough to send complete routing updates to the
remote routers. The inactivity timer, which starts at the same time as the minimum
duration timer, determines how long the connection remains active by monitoring
data inactivity. When there is no more data going across the line, the inactivity
time expires and the router brings down the connection.
