• Nonstandard—The nonstandard encapsulation type is compatible with dedicated
encapsulation types of mainstream routers.
If a VC is enabled with STAC compression, its encapsulation type can only be IETF.
When a Frame Relay interface is configured with an encapsulation type:
• The interface sends packets encapsulated in this type.
• The interface can recognize packets encapsulated in either type.
For the local end and the peer to communicate:
• If the peer can recognize packets in either type, you can set different encapsulation types on the
two ends.
• If the peer cannot recognize packets in either type,, you must set the same encapsulation type
on the two ends.
By default, a VC uses the encapsulation type configured on i ts Frame Relay interface. The
encapsulation type configured for a VC takes precedence over the encapsulation type configured on
its Frame Relay interface.
Examples
# Enable Frame Relay encapsulation on Serial 2/1/0, and set the encapsulation type to nonstandard.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] link-protocol fr
[Sysname-Serial2/1/0] fr encapsulation nonstandard
# Set the Frame Relay encapsulation type to IETF on the VC with DLCI 200.
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] fr dlci 200
[Sysname-Serial2/1/0-fr-dlci-200] fr encapsulation ietf
fr fragment enable
Use fr fragment enable to enable Frame Relay FRF.12 fragmentation on a Frame Relay interface.
Use undo fr fragment enable to disable Frame Relay FRF.12 fragmentation on a Frame Relay
interface.
Syntax
fr fragment enable
undo fr fragment enable
Default
Frame Relay FRF.12 fragmentation is disabled on a Frame Relay interface.
Views

Usage guidelines
This command enables FRF.12 fragmentation on all PVCs of an interface and its subinterfaces.
FRF.12 fragmentation enabled by using this command is end-to-end type.
