Configuring the Frequency of RST Messages on Low Priority Routes

This procedure is used to configure the frequency that signaling-route-set-test messages are sent for routes of lower priority than the current route. The frequency is configured with these parameters of the chg-stpopts command.

:on=mtplprst - to turn on the routeset test message for lower priority routes capability. The EAGLE sends routeset test messages at intervals specified by the value of the mtpt10alt parameter.

:off=mtplprst - to turn off the routeset test message for lower priority routes capability. The EAGLE does not send routeset test messages for the lower priority routes.

:mtpt10alt – the timer to control the frequency that the routeset test messages are sent. The values for this parameter are from 20000 to 10,000,000 milliseconds (20 - 10,000 seconds).

The value of the mtpt10alt parameter must be equal to or greater than the value of the level 3 T10 timer.

When the on=mtplprst parameter is specified for the chg-stpopts command, the value yes is shown in the MTPLPRST field of the rtrv-stpopts output. When the off=mtplprst parameter is specified for the chg-stpopts command, the value no is shown in the MTPLPRST field of the rtrv-stpopts output.

The system default values, shown in the rtrv-stpopts output, for these parameters are:

MTPLPRST - yes
MTPT10ALT - equal to the value of the level 3 T10 timer. The value of the level 3 T10 timer is shown in the T10 field of the rtrv-l3t command output

If the Origin-Based MTP Routing feature is enabled and turned on, the off=mtplprst parameter cannot be specified with the chg-stpopts command. The status of the Origin-Based MTP Routing feature is shown in the rtrv-ctrl-feat command output.

These parameters of the chg-stpopts command are optional. For any parameters not specified with the chg-stpopts command, the values for these parameters are not changed.

For this example, the sending the signaling-route-set-test messages for the low priority routes is turned on, and the frequency of sending these messages is changed from 30,000 milliseconds to 120,000 milliseconds (30 seconds to 120 seconds).

Display the current MTPLPRST and MTPT10ALT values by entering the rtrv-stpopts command.
The MTPT10ALT value is shown in milliseconds.This is an example of the possible output.

Note:
The rtrv-stpopts command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-stpopts command, see the rtrv-stpopts command description in Commands User's Guide.

If the MTPLPRST value is not being changed, or if the MTPLPRST value is being changed from no to yes, continue the procedure with 3.

If the MTPLPRST value is being changed from yes to no, continue the procedure with 2.

Display the status of the Origin-Based MTP Routing feature by entering this command.

rtrv-ctrl-feat:partnum=893014201

This is an example of the possible output.

If the Origin-Based MTP Routing feature is enabled and turned on, shown with entry on in the Status column, the MTPLPRST value cannot be changed to no.

Display the values for the level 3 timer set using the rtrv-l3t command.

The values of the level 3 timers are shown in seconds. This is an example of the possible output.

- on=mtplprst - if the current MTPLPRST value is no.
- off=mtplprst - if the current MTPLPRST value is yes.
- mtpt10alt
For this example, enter this command.

chg-stpopts:on=mtplprst:mtpt10alt=120000

When this command has successfully completed, this message should appear.
