• Configure the router to handle oversubscription of lines.

If you do not have enough lines to accommodate the number of circuits, you

can enable an oversubscription timer. This timer determines how often the

router retries a connection so it can send routing updates if the previous

attempt failed. The router keeps a list of circuits requesting connections and

tries to establish these connections when the timer expires.

To configure the oversubscription timer, you must use the Technician

Interface; you cannot do this using Site Manager. The attribute entry is

wfSwservOptsEntry.wfSwservOptsOverSubRetryTimer. The default value is

two minutes; the maximum value is 1440 minutes.

See Configuring IP Services for information about RIP and Configuring IPX

Services for information about RIP/SAP.

IP RIP Triggered Updates and Broadcast Timers

To prevent broadcast messages from keeping the demand circuit active, you can

configure the RIP broadcast timer and triggered updates.

The broadcast timer lets you configure how often the router sends routing updates

to the network. Unlike the broadcast timer, triggered updates are sent immediately

after the router detects a routing change in the network.

If you set the broadcast timer to a high value, for example, several hours, and you

enable triggered updates, you limit the frequency of broadcast traffic while

maintaining the accuracy of the routing tables. By limiting broadcast traffic, you

prevent the demand circuit from remaining active unnecessarily.

For more information about these RIP features, see Configuring IP Services.

IPX RIP and SAP Broadcast Timers

To prevent broadcast messages from keeping the demand circuit active, you can

configure RIP and SAP broadcast timers for IPX transmission. RIP and SAP

broadcast timers enable you to control how often update transmissions occur. You

can even eliminate RIP and SAP broadcasts entirely. By controlling broadcast

traffic, you can prevent the demand circuit from remaining active unnecessarily.

For more information about broadcast timers, see Configuring IPX Services.
