  RFC 3034 (rfc3034) - Use of Label Switching on Frame Relay Networks Specif   (Site not responding. Last check: 2007-10-14)
The DLCI for the LDP VC is assigned a value by way of configuration, similar to configuring the DLCI used to run IP routing protocols between the switches.
With the exception of this configured value, the DLCI values used for MPLS in the two directions of the link may be treated as belonging to two independent spaces, i.e., VCs may be half-duplex, each direction with its own DLCI.
Maximum DLCI This 23 bit field is the binary value of the upper bound of a block of Data Link Connection Identifiers (DLCIs) that is supported by the originating FR-LSR.

 RFC 2590 (rfc2590) - Transmission of IPv6 Packets over Frame Relay Network
Since DLCIs are local to a Frame Relay node, it is possible to have Frame Relay distinct virtual circuits within a Frame Relay network identified with the same DLCI values.
In other words, the DLCI that identifies the Frame Relay virtual circuit at the sender may be different than the DLCI that identifies the virtual circuit at the receiver node.
The passing of the DLCI value from the Frame Relay module to the Neighbor Discovery preprocessing module is an implementation choice.

 Cisco Systems Configuring Frame Relay
You must associate the Frame Relay DLCI with a subinterface to use subinterfaces in the Frame Relay network for point-to-point communication.
The incoming DLCI is examined, and the outgoing interface and DLCI are determined.
Frames with DLCI 100 received on serial 1 will be transmitted with DLCI 200 on serial 2 (see Figure 1-3).

 CONFIGURING FRAME-RELAY SUB-INTERFACES (DLCI BUNDLING)
Learning DLCIs from the Frame Relay switch (using LMI or Annex-d polling) works only on the primary interface and not on the sub interface.
Currently the add dlci command is used for both the primary and sub interfaces.
Verify that the local IP address for the sub interface is in the same subnet or IP network as all other Frame Relay interfaces of the other routers and that all the netmasks match.

 Annex G (X.25 over Frame Relay)
Each Frame Relay DLCI can only be configured for one Frame Relay service at a time.
This command allows the option of restarting an Annex G connection per DLCI number, clearing all X.25 connections, or clearing a specific X.25 logical circuit number on that Annex G link.
A Frame Relay DLCI configured for Annex G can be thought of as a single logical X.25/LAPB interface.

 Emerging Technologies
A DLCI is a channel number (the technical term is "data link connection identifier") which is attached to data frames to tell the network how to route the data.
The DLCI allows the data to be logically tied to one of the connections so that once it gets to the network it knows where to send it.
As explained before, each remote location is connected to the hub location with a DLCI, and all of the DLCIs are aggregated on a single T1, all of which is just fine and dandy.

 Frame Relay, DLCI, CIR
DLCI 1023 is the LMI control DLCI at the switch.
IP addresses are assigned to the interface and configuration applies to the interface and therefore all PVCs associated with that interface.
The ARP packet is sent to all active DLCIs and the network address is mapped to the local DLCI through which the reply was received.

 DLCI - Data Link Connection Identifier
The DLCI is the Data Link Connection Identifier and is used to identify a unique virtual point to point connection via a Frame Relay network.
The DLCI number is local to the frame access device and frame relay switch it connects to, and it is generally changed by the switch within the network, because the receiving switch uses a different DLCI for the same connection.
Each DLC from a given station has a different DLCI, but the same DLC can be identified by different DLCIs by the two stations at each end of the DLC.

 Sangoma - Frame Relay Tutorial   (Site not responding. Last check: 2007-10-14)
Most Virtual Circuits are Permanent Virtual Circuits or PVCs, which means that the network provider sets up all DLCI connections at subscription time.
Sangoma's WANPIPE® and APIs support up to 250 DLCIs per physical link, allowing servers to be used as substantial network hubs.
Until the first FS exchange has occurred, the CPE does not know which DLCIs are active, and so no data transfer can take place.

 DLCI (10-24 bits) (Frame Relay)   (Site not responding. Last check: 2007-10-14)
DLCI numbers identify a point-to-point link, not an end-to-end (DTE-to-DTE) service connection.
The Frame Relay header is 2 bytes in length at least with a minimum DLCI length of 10 bits.
Using the address extension function, the DLCI may be 10 (2 header octets), 17 (3 header octets), or 24 bits (4 header octets) in length.

 Setting Up Frame Relay in RADIUS
A DLCI is a number between 16 and 991 that the frame relay administrator assigns.
A DLCI is not an address, but a local label that identifies a logical link between a device and a frame relay switch.
If any one of the DLCIs in a PVC becomes inactive because of disconnect or failure, the PVC using that DLCI becomes inactive.

 DLCI Assignments
Because the Cisco 90i IDSL Channel Unit performs a DLCI translation for Frame Relay traffic both to and from a subscriber, this appendix lists the network DLCI assignments and corresponding subscriber DLCI assignments for every possible slot and port in a 64-slot D4 channel bank digroup.
Port A on the Cisco 90i corresponds to port 0, port B to 1, port C to 2, and port D to 3.
The Network DLCI table is arranged by slot and port number.

 Frame Relay
The Frame Relay protocol uses a frame structured similar to that of LAPD, except that the frame header is replaced by a 2-byte Frame Relay header field.
This information is transmitted using the reserved DLCI 1023 or DLCI 0, depending on the standard used.
Multicasting is where a router sends a frame on a reserved DLCI known as a multicast group.

 Sem 4 Frame Relay
DLCI numbers are not unique identifiers on the network; instead, they have only local significance, which means they are important only to the local router and Frame Relay switch.
DLCI numbers are mapped, or assigned, to a specific interface.
The router uses the Frame Relay map to determine the DLCI of the next hop.

 DLCI Allocation in Client/Server Applications 1
Logically these 2 DLCI connections are mapped on the same server channel value (DLC) 1.
In simple terms server application on the non-initiating device are allocated DLCIs 2,4,6,…,60 (even numbers); and server applications on the initiating device are allocated DLCIs 3,5,7,…,61 (odd numbers).
This DLCI value is valid only within the device itself.

 Frame relay - Standards: DLCI   (Site not responding. Last check: 2007-10-14)
By assigning different DLCI values to different frames, we can create several simultaneous logical connections on the same physical circuit.
The DLCI value has only local significance (between two nodes) so it might have to be changed on its way through the network.
If a LAN is to set up a frame-relay connection to another LAN, the router will interpret the address of the packet (an IP address, for instance) and place the appropriate DLCI value(s) in the address field of the frame-relay frame, so the PVC reaches the address indicated.

 Global DLCI addressing
When the router constructs the header of an outbound frame, it inserts the DLCI value of the destination (rather than a DLCI value from the local pool of unused numbers).
The downside is that it has a size ceiling, because of the limited size of the DLCI field.
If you are involved in setting up DLCIs for your frame rely sites, it can be helpful to ask your carrier which approach to addressing is supported in the carrier's switches - local or global - so that you use the scheme supported by your provider.

 Cisco CCIE Certification and CCNP Certification FAQs: How do I disable frame relay inverse arp?
Whatever set of DLCI's you have attached to the physical or multipoint subinterface - by default there is an inverse arp.
If you want to disable it on all DLCIs that are terminated on the interface or a multipoint subinterface - use no frame inverse-arp under that interface.
InARP is not enabled for a DLCI assigned to a P2P subinterface as layer 3 to layer 2 mapping is automatic for a P2P subinterface.

 Cisco Frame Relay Configurations   (Site not responding. Last check: 2007-10-14)
In this example, the local referenced DLCI of the VC at hub router R3 and spoke router R4 are 304 and 403, respectively.
For instance, in the configuration examples in Example 4-22, DLCIs 301, 302, and 304 are automatically associated with the physical interface serial 3/1 on the hub router R3.
When a multipoint subinterface is created on a physical interface, the DLCIs of virtual circuits are always assigned to the physical interface until they are specifically assigned to the subinterfaces using the frame-relay interface-dlci dlci command or the frame-relay map protocol protocol-address dlci [broadcast] command.

 TIP: Use the Learned DLCI Display as a Troubleshooting Aid
This display will show the DLCI's reported from the frame relay service and their corresponding state.
Across both links, only five DLCIs are presently considered up and operational, communicating with a partner in their respective remote location.
Since this information is derived from the LMI Full Status Report, this display can be used as a validation of the information the Frame Relay service provider has given you.

Are you asking to remove that dlci from the router, if so.
once the interface with the dlci or at least the dlci is removed use 'no frame-relay interface-dlci 98' cmd from within the interface, then end and write, copy run config to startup config.
It's not configured, I believe it is a test dlci discovered when the telco was testing.
