Target:

Basic Frame Relay Configuration

Lab device:

Router with serial port) 2

V.35 cable DTE/DCE) 1 pair

Tutorial principle:

The frame relay standard can be configured and managed permanent virtual circuit PVC in the frame relay network) for addressing, and the frame relay permanent virtual circuit is identified by the data link connection identifier DLCI.

When frame relay provides multiple methods for multiple Logical Data sessions, the ISP's switching device must first create a table to map different DLCI values to the outbound port. Second, when a data frame is received, the Exchange Device analyzes its connection identifier and sends the data frame to the corresponding port. Finally, a full path to the destination will be created before the first data frame is sent.

Step:

Step 1. Configure the vro.

Router A (config) # interface serial 4/0

Router A (config-if) # ip address 1.1.1.1 255.255.0

Router A (config-if) # exit

Router A (config) # interface Fast Ethernet 1/0

Router A (config-if) # ip address 192.168.1.1 255.255.0

Router A (config-if) # exit

Router B (config) # interface serial 4/0

Router B (config-if) # ip address 1.1.1.2 255.255.0

Router B (config-if) # exit

Router B (config) # interface Fast Ethernet 1/0

Router B (config-if) # ip address 192.168.2.1 255.255.255.0

Router B (config-if) # exit

Step 2 configure frame relay.

Router A (config) # interface serial 4/0

Router A (config-if) # encapsulation frame-relay ietf

Router A (config-if) # frame-relay map ip 1.1.1.2 16

Router A (config-if) # frame-relay lm-type ansi

Router B (config) # interface serial 4/0

Router B (config-if) # encapsulation frame-relay ietf

Router B (config-if) # frame-relay map ip 1.1.1.1 17

Router B (config-if) # frame-relay lm-type ansi

Step 3. Verify the Frame Relay configuration.

Router B # show frame-relay pvc

Note]

When the WAN protocol is encapsulated, the two port encapsulation protocols of the V.35 cable must be consistent. Otherwise, a link cannot be established.
