Configure LAPB
parameters
Quit to system view

Create a VC
Apply the X.25 template to
the DLCI

CAUTION:
With FR address mapping configured in FR interface view, packets destined for
■
the destination are transmitted through specific DLCI. With X.25 address
mapping configured in X.25 template view, a call to the specific X.25 address is
launched before a packet is sent to the destination IP address. IP packets can
be transmitted correctly only when the both types of address mappings are
configured.
The configuration performed in X.25 template view is similar to that performed
■
in X.25 interface view. To establish an X.25 link successfully, the configurations
on the routers of both sides need to be consistent with each other.
Follow these steps to configure DCE side frame relay:
To do...
Enter system view
Enter interface view
Configure interface

Remarks
Required
This command also leads you to
X.25 template view.

Required
This command also leads you to
interface DLCI view.
By default, no VC is created on
an interface.
Optional
By default, a DLCI has no X.25
template applied to it.
Remarks

Required
The link layer protocol for
interface encapsulation is PPP
by default. When frame relay
protocol is used for interface
encapsulation, the default
operating mode is IETF.
