Reset map table and clears all inverse arp entries. Router no debug frame relay lmi.

Lmi types are the signaling standards between a router cpe and fr switch telco.

. For example if branch 1 sends an update to headquarter then headquarter can t send that update to branch 2 because they are received and sent on the same interface. We also verify that we can ping. In this example we use show frame relay mapping to verify that r4 has learned about the other links via inverse arp. Ip 131 108 122 2 dlci 20 0x14 0x0440 dynamic cisco bw 56000 status defined active table 9 3 describes significant fields shown in the display.Ip 10 4 4 3 dlci 403 0x193 0x6430 dynamic broadcast. Router debug frame relay lmi. This value is. Basic frame relay configuration with both inverse arp and frame relay map command here we will talk about two options for configuring frame relay maps.
The table contains both dynamic mapped and static mapped entries. Used to view the status of all pvcs configured. R4 config if do sh frame map serial0 0 up. To show this in a basic topology we will use the below topology configured with three cisco 3600 series routers.
Dlci 20 0x14 0x0440 dlci that identifies the logical connection being used to reach this interface. We should use the broadcast keyword here because by default split horizon will prevent routing updates from being sent back on the same interface it received. Show frame relay map field descriptions. Sample show frame relay map output.
Displays lmi statistics including types and exchanged messages. The ip map has inherited passive tcp ip header compression. Testing connectivity on our hosts is the last thing we need to do in this lab we can verify that all the three routers have the routes learnt via eigrp as shown from the output of r3 below. R1 sh frame mapserial0 0 up.
The show frame relay map privileged exec mode command shows the contents of the next hop protocol address to dlci mapping table on the router. This command verifies the dlci mappings that the router has learned about. Access server show frame relay map serial 1 administratively down. Show frame relay map on each of the routers as shown below for r1 and r3.
One is inverse arp and the other is with frame relay map command. It serves as the heartbeat of the link between the two devices which verifies the flow of data on that link. Identifies a frame relay interface and its status up or down. Enable debug process on lmi.
Router show frame relay map. Ip 10 4 4 1 dlci 401 0x191 0x6410 dynamic broadcast status defined active serial0 0 up. Ip 172 30 177 177 dlci 177 0xb1 0x2c10 static broadcast cisco tcp ip header compression inherited passive inherited this example also applies to dynamic mappings achieved with the use of inverse arp on point to point subinterfaces where no. Router show frame relay map serial2 up.
Used to view ip dlci map entries. To verify the static frame relay mapping use the command. Frame relay lmi specifications are ansi q933a and cisco though the question is about the output of show frame relay map not show frame relay lmi. Use of the show frame relay map command will display the resulting compression and encapsulation characteristics.
Lmi specifications differ with encapsulation types. Example 4 32 sample output of show frame relay map command. Encapsulation types deal with the framing of a frame relay packet. Ip 10 4 4 1 dlci 401 0x191 0x6410 dynamic broadcast status defined.
By using the broadcast. Headquarter config if frame relay map ip 1 1 1 1 23 broadcast headquarter config if frame relay map ip 2 2 2 2 51 broadcast. Clears all frame relay counters. Ieee and 802 1q trunking has.
Example 4 32 shows a sample output of the show frame relay map command.
