Frame Relay <strong>Configuration</strong> ExamplesConfiguring Frame RelayIP Map with Inherited TCP/IP Header Compression ExampleThe following example shows an interface configured for TCP/IP header compression and an IP map thatinherits the compression characteristics. Note that the Frame Relay IP map is not explicitly configuredfor header compression.interface serial 1encapsulation frame-relayip address 131.108.177.178 255.255.255.0frame-relay map ip 131.108.177.177 177 broadcastframe-relay ip tcp header-compression passiveUse of the show frame-relay map command will display the resulting compression and encapsulationcharacteristics; the IP map has inherited passive TCP/IP header compression:Router> show frame-relay mapSerial 1 (administratively down): ip 131.108.177.177dlci 177 (0xB1,0x2C10), static,broadcast,CISCOTCP/IP Header Compression (inherited), passive (inherited)This example also applies to dynamic mappings achieved with the use of Inverse ARP on point-to-pointsubinterfaces where no Frame Relay maps are configured.Using an IP Map to Override TCP/IP Header Compression ExampleThe following example shows the use of a Frame Relay IP map to override the compression set on theinterface:interface serial 1encapsulation frame-relayip address 131.108.177.178 255.255.255.0frame-relay map ip 131.108.177.177 177 broadcast nocompressframe-relay ip tcp header-compression passiveUse of the show frame-relay map command will display the resulting compression and encapsulationcharacteristics; the IP map has not inherited TCP header compression:Router> show frame-relay mapSerial 1 (administratively down): ip 131.108.177.177dlci 177 (0xB1,0x2C10), static,broadcast,CISCONoteShut down the interface or subinterface prior to adding or changing compression techniques. Althoughshutdown is not required, shutting down the interface ensures that it is reset for the new data structures.Disabling Inherited TCP/IP Header Compression ExampleIn this example, the following is the initial configuration:interface serial 1encapsulation frame-relayip address 131.108.177.179 255.255.255.0frame-relay ip tcp header-compression passiveframe-relay map ip 131.108.177.177 177 broadcast74
Configuring Frame RelayFrame Relay <strong>Configuration</strong> Examplesframe-relay map ip 131.108.177.178 178 broadcast tcp header-compressionEnter the following commands to enable inherited TCP/IP header compression:serial interface 1no frame-relay ip tcp header-compressionUse of the show frame-relay map command will display the resulting compression and encapsulationcharacteristics:Router> show frame-relay mapSerial 1 (administratively down): ip 131.108.177.177 177dlci 177(0xB1, 0x2C10), static,broadcastCISCOSerial 1 (administratively down): ip 131.108.177.178 178dlci 178(0xB2,0x2C20), staticbroadcastCISCOTCP/IP Header Compression (enabled)As a result, header compression is disabled for the first map (with DLCI 177), which inherited its headercompression characteristics from the interface. However, header compression is not disabled for thesecond map (DLCI 178), which is explicitly configured for header compression.Disabling Explicit TCP/IP Header Compression ExampleIn this example, the initial configuration is the same as in the preceding example, but you must enter thefollowing set of commands to enable explicit TCP/IP header compression:serial interface 1no frame-relay ip tcp header-compressionframe-relay map ip 131.108.177.178 178 nocompressUse of the show frame-relay map command will display the resulting compression and encapsulationcharacteristics:Router> show frame-relay mapSerial 1 (administratively down): ip 131.108.177.177 177dlci 177(0xB1,0x2C10), static,broadcastCISCOSerial 1 (administratively down): ip 131.108.177.178 178dlci 178(0xB2,0x2C20), staticbroadcastCISCOThe result of the commands is to disable header compression for the first map (with DLCI 177), whichinherited its header compression characteristics from the interface, and also explicitly to disable headercompression for the second map (with DLCI 178), which was explicitly configured for headercompression.75
