Configuring Frame Relay
Use to configure a Frame Relay interface circuit to operate as data
communications equipment (DCE), data terminal equipment (DTE), or NNI.
Frame Relay provides packet-switching data communications between user
devices and network equipment across the interface. User devices are referred
to as DTE.
Network equipment that interfaces with a DTE is referred to as a DCE.
NNI provides a connection between two Frame Relay subnetworks.
If your router is connected to a Frame Relay switch, configure the interface as
a DTE. If your router is connected by a point-to-point line, configure one end as
the DTE and the other as the DCE.
Example
host1(config-if)#frame-relay intf-type dte
Use the no version to set the default of DTE.
See frame-relay intf-type.
Use to enable the LMI on the interface.
You can specify the keepalive interval in seconds.
Make sure the value on the DTE is less than the value set on the DCE.
The default is 10 seconds.
Example
host1#no frame-relay keepalive
Use the no version to disable LMI on the interface.
See frame-relay keepalive.
