Customizing Frame Relay for Your NetworkConfiguring Frame Relay2. If the CSA is not available, compression is performed in the software installed on the VIP2 card(distributed compression).3. If the VIP2 card is not available, compression is performed in the main processor of the router(software compression).Configuring FRF.9 Compression Using Map StatementsYou can control where you want compression to occur by specifying an interface. To enable FRF.9compression on a specific CSA, VIP CPU, or host CPU, use the following commands beginning in globalconfiguration mode:CommandConfiguring FRF.9 Compression on the SubinterfacePurposeStep 1 Router(config)# interface type number Specifies the interface.Step 2 Router(config-if)# encapsulation frame-relay Specifies Frame Relay as encapsulationtype.Step 3Router(config-if)# frame-relay map payload-compression frf9stac [hardware-options]Enables FRF.9 compression.To configure FRF.9 compression on the subinterface, use the following commands beginning in globalconfiguration mode:CommandConfiguring Data-Stream CompressionPurposeStep 1 Router(config)# interface type number Specifies the subinterface type andnumber.Step 2 Router(config-subif)# encapsulation frame-relay Specifies Frame Relay as encapsulationtype.Step 3Router(config-subif)# frame-relay payload-compression frf9stac [hardware-options]Enables FRF.9 compression.Data-stream compression is a proprietary hardware and software compression protocol that can be usedon the same VC or interface and IP header compression. Data-stream compression is functionallyequivalent to FRF.9 compression and must be used with Cisco-proprietary encapsulation. Frame Relayfragmentation can also be used with data-stream compression.To configure data-stream compression with IP header compression, perform the tasks in the followingsections:• Configuring Data-Stream Hardware Compression and IP Header Compression on a Point-to-PointSubinterface• Configuring Data-Stream Hardware Compression and IP Header Compression on a MultipointSubinterface44
Configuring Frame RelayCustomizing Frame Relay for Your NetworkConfiguring Data-Stream Hardware Compression and IP Header Compression on a Point-to-Point SubinterfaceTo configure data-stream hardware compression and TCP or Real-Time Transport Protocol (RTP) headercompression on a point-to-point subinterface, use the following commands beginning in globalconfiguration mode. Note that when you specify data-stream hardware compression, Cisco-proprietaryencapsulation is automatically enabled.CommandPurposeStep 1 Router(config)# interface type number point-to-point Configures a subinterface type and enterssubinterface configuration mode.Step 2 Router(config-subif)# ip address address mask Sets the IP address for an interface.Step 3 Router(config-subif)# frame-relay interface-dlci dlci Assigns a DLCI to a specified Frame Relaysubinterface on the router or access server.Step 4Step 5Router(config-subif)# frame-relay payload-compressiondata-stream stac [hardware-options]Router(config-subif)# frame-relay ip tcpheader-compression [passive]orEnables hardware compression on an interface orsubinterface that uses Cisco-proprietaryencapsulation.Configures an interface to ensure that theassociated PVCs carry outgoing TCP headers incompressed form.Router(config-subif)# frame-relay ip rtpheader-compression [passive]Enables RTP header compression on the physicalinterface.For an example of data-stream compression and IP header compression configured on a point-to-pointsubinterface, see the section “Data-Stream Hardware Compression with TCP/IP Header Compression ona Point-to-Point Subinterface Example” later in this chapter.Configuring Data-Stream Hardware Compression and IP Header Compression on a Multipoint SubinterfaceTo configure data-stream hardware compression and TCP or RTP header compression on a multipointsubinterface, use the following commands beginning in global configuration mode. Note that when youspecify data-stream hardware compression, Cisco-proprietary encapsulation is automatically enabled.CommandPurposeStep 1 Router(config)# interface type number multipoint Configures a subinterface type and enterssubinterface configuration mode.Step 2 Router(config-subif)# frame-relay interface-dlci dlci Assigns a DLCI to a specified Frame Relaysubinterface on the router or access server.45
