Configuring DTE side frame relay
Configuring basic DTE side frame relay
To configure DTE side frame relay:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the interface
encapsulation protocol as
frame relay.
link-protocol fr [ ietf |
nonstandard ]
The default link layer protocol of an
interface is PPP. When frame relay
is configured as the link layer
protocol, the encapsulation format
is defaulted to IETF.
4. Configure the frame relay
interface type as DTE.
fr interface-type dte
Optional.
The default frame relay interface
type is DTE.
5. Configure frame relay LMI
protocol type. fr lmi type { ansi | nonstandard |
q933a }
Optional.
The default frame relay LMI
protocol type is q933a.
6. Configure user side N391. fr lmi n391dte n391-value
Optional.
The default value is 6.
7. Configure user side N392. fr lmi n392dte n392-value
Optional.
The default value is 3.
8. Configure user side N393. fr lmi n393dte n393-value
Optional.
The default value is 4.
9. Configure user side T391. timer hold seconds
Optional.
The default value is 10 seconds.
Configuring frame relay address mappings
Overview
Configure frame relay address mappings in one of the following ways:
• Manually creating static mappings between peer IP addresses and local DLCIs.
Use this approach when the network topology is relatively stable and no new users are expected
in a certain period of time. Because static mappings do not change, the network connections are
stable, and attacks from unknown users are avoided.
• Using InARP to dynamically create mappings between peer IP addresses and local DLCIs.
Use this approach in complicated networks and make sure that the peer router also supports
InARP.
