Matching DLCIs ensures that a backup exists for each PVC 117376 B Rev 00 2 29 Configuring Frame Relay Services The most important part of configuring multiline is setting the PVC DLCI number This number identifies each PVC thereby specifying a path for the router to direct data to the network For each frame relay PVC that you configure check that PVCs with the same destination have the same DLCI number Note If you use multiline packets traveling on the two paths may arrive at their destination out of sequence Some protocols do not tolerate packets arriving out of sequence and as a result you may experience poor performance or failures For instructions about grouping service records for multiline see Chapter 3 Customizing Frame Relay Traffic Distribution Between Data Paths To distribute traffic between multiline data paths you can use one of two methods e Random distribution e Address based distribution Random Distribution Random distribution means that as the router sends out each packet it alternates between the lines This option determines which line the packet uses based on a randomly assigned number For each outbound packet the router generates a random number and this number designates the line to use Random balancing evenly distributes traffic and lets the router use the two lines efficiently Because packets travel on different paths they arrive at the destination out of sequence a

The sum of the B and the B is the maximum amount of traffic that can travel across the network per T when there is no congestion If you set the B to a value greater than zero the router can send traffic exceeding the CIR To enforce the CIR that is to limit traffic that the router can send to the amount of the CIR set the B to 0 If you enable congestion control and set the congestion method to throttle the VC sends only B bits of data over the time interval T when congestion occurs even if you have configured the B to a value greater than 0 It queues the excess data until congestion abates If you set the congestion method to throttle then shutdown the VC first queues traffic when congestion occurs and then terminates the VC if throttling does not alleviate congestion Quality of Service Quality of Service QoS is the second major component of Bay Networks traffic shaping It uses protocol prioritization with traffic shaping You configure a prioritization filter on the default service record for the entire frame relay interface and CIR enforcement per VC QoS operates over Synchronous HSSI T1 El and ISDN lines for backup demand and for leased lines Although the HSSI driver does not support protocol prioritization VCs on an HSSI interface do 117376 B Rev 00 2 19 Configuring Frame Relay Services Using protocol prioritization with traffic shaping creates two levels of queues For traffic shaping the queues ar

24. PVCs Frame relay provides a link redundancy feature called multiline which works with frame relay PVCs Multiline is a Bay Networks proprietary implementation that lets you group two or more physical lines that back each other up in case of a failure This ensures that information arrives at its destination on the network In addition if both lines are up the router uses both lines simultaneously Two or more physical lines must be available for a multiline configuration Figure 2 11 illustrates a multiline configuration DLCI 200 DLCI100 j ineA Frame relay network Router Router DLCI100 Line B DLCI 200 FR0009A Figure 2 11 Multiline Network In this example when the router receives traffic destined for the network it alternates or randomizes depending on how you configure it between line A and line B to transmit the data The router uses both lines simultaneously to balance the traffic between each path If one of these lines goes down the router uses the remaining line You can create a multiline configuration of up to four service records Each service record must be on a different physical line on the router Each line should be on a different slot to provide fault tolerance You must also match DLCIs in each service record of the multiline
