# Frame Relay and Multilink Frame Relay Options

After you configure an interface for Frame Relay encapsulation in the interface's Basic Properties, you can configure Frame Relay options.

- To configure Frame Relay options, click FR.

  To configure Frame Relay options:

  1. Enter the following:

  No-Keepalive: Select this option to disable the sending of keepalives on the interface.

  Type: Select the type of Local Management Interface (LMI) keepalive packets:

  - Ansi is ANSI T1.617 Annex D

  - Itu is ITU Q933 Annex A

  DTE Full Status Polling Interval: Enter the frequency at which status inquiries expect a full status report.

  DTE Error Threshold: Enter the number of errors required to bring down the link. This number must be within the DTE Monitored Event Count value.

  DTE Monitored Event Count: Enter the number of DTE monitored events.

  DTE Keepalive Interval: Enter the interval, in seconds, at which the DTE sends out a keepalive response request to the DCE.

  2. Click Apply.

After you create a bundle (also referred to as a multilink interface) and configure it for Multilink Frame Relay (MLFR) encapsulation, you can configure MLFR options for the bundle.

- To configure MLFR options for a bundle, click MLFR.

  To configure MLFR options for a bundle:

  1. Enter the following:

  No-Keepalive: Select this option to disable the sending of keepalives on the interface.

  Type: Select the type of Local Management Interface (LMI) keepalive packets:

  - Ansi is ANSI T1.617 Annex D

  - Itu is ITU Q933 Annex A

  DTE Full Status Polling Interval: Enter the frequency at which status inquiries expect a full status report.

  DTE Error Threshold: Enter the number of errors required to bring down the link. This number must be within the DTE Monitored Event Count value.

  DTE Monitored Event Count: Enter the number of DTE monitored events.

  DTE Keepalive Interval: Enter the interval, in seconds, at which the DTE sends out a keepalive response request to the DCE.

  Drop Timeout: Enter the timeout, in seconds, if links in the bundle drop one or more packets. A value of 0 means that drop timeout is disabled.

  Minimum Links: Enter the minimum number of bundle links that must be up for the bundle to be considered to be up.

  2. Click Apply.

After you assign a bundle link to a bundle, you can configure MLFR options for each bundle link.

- To configure MLFR options for a bundle link, click MLFR.

  To configure MLFR options for a bundle link:

  1. Enter the following:

  LIP Retransmission Count before Link-Down: Enter the number of retransmission attempts to be made for consecutive hello or remove link messages after the expiration of an acknowledgement timer.

  Maximum Period to Wait for an Acknowledgement: Enter the maximum period, in milliseconds, to wait for an add link, hello, or remove link acknowledgement..

  Bundle-link Fragmentation Threshold: Enter the maximum size, in bytes, for packet payloads transmitted across the bundle links.

  LIP Hello Keepalive Interval: Enter the rate, in milliseconds, at which hello messages are sent.

  2. Click Apply.
