Please Input the code of command to be excute(0-1): 1
Subinterfaces can be configured for multipoint or point-to-point communication. (There is no default.)
2. Specify Subinterface Address
For frame relay subinterface, the particular subinterface DLCI value can be configured by set
frame-relay local-dlci command if the main interface work in the DCE mode. The target end can be
dynamic resolve through reverse ARP or static mapping by map command
5.4.5 Configure DLCI
Use following command to configure DLCI value of subinterface:
Command
Frame-relay (undo) local-dlci
dlci [cir speed]
Key Word:
Q(quit)
......
(14)fair-queue
(15)frame-relay
......
Please Input the code of command to be excute(0-32): 15
Key Word:
U(undo) D(default)
......
(03)lmi-type
(04)local-dlci
......
Please Input the code of command to be excute(0-10): 4
Key Word:
Q(quit)
(00)<16-1007>
Please Input the code of command to be excute(0-0): 0
Please input a digital number:Please input a string:100 （input the DLCI number）
Key Word:
Q(quit)
(00)cir
(01)<cr>
Please Input the code of command to be excute(0-0): 1
Note:
This command can use for both subinterface and main interface. Only one DLCI can be configured for point-to-point
subinterface.
5.4.6 Configure Inverse ARP for Dynamic Address Mapping on Subinterfaces
Dynamic address mapping uses Frame Relay Inverse ARP to request the next-hop protocol address
for a specific connection, given a DLCI. Responses to Inverse ARP requests are entered in an
address-to-DLCI mapping table on the router; the table is then used to supply the next-hop protocol
address or the DLCI for outgoing traffic.
Since the physical interface is now configured as multiple subinterfaces, you must provide information
that distinguishes a subinterface from the physical interface. Inverse ARP must be enabled in main
interface so that the interface can create Dynamic Address Mapping by Inverse ARP .
To associate a subinterface with a specific DLCI, perform the following command:
Command
Model Name
[delete/specify]DLCI of subinterface
enable fair queue on interface
Set parameters for Framerelay
Q(quit)
Set LMI type(q933a/ansi/lmi)
Set local DLCI parameters
Local DLCI
Set committed information rate
