Configuring Tunable Keepalives For Frame Relay Lmi - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

JUNOS 10.1 Network Interfaces Configuration Guide
To disable the sending of keepalives on a physical interface, include the
statement at the
For back-to-back Frame Relay connections, either disable the sending of keepalives
on both sides of the connection, or configure one side of the connection as a data
terminal equipment (DTE) (the default JUNOS configuration) and the other as a data
circuit-terminating equipment (DCE).
If keepalives are enabled, the number of possible DLCI configurations on a multipoint
or multicast connection is limited by the MTU size selected for the interface. To
calculate the available DLCIs, use the formula (MTU – 12) /5. To increase the number
of possible DLCIs, disable keepalives.

Configuring Tunable Keepalives for Frame Relay LMI

On interfaces configured with Frame Relay connections, you can tune the keepalive
settings by using the
DTE (the default JUNOS configuration). DTE acts as a master, requesting status from
the DCE part of the link.
By default, the JUNOS Software uses ANSI T1.617 Annex D LMIs. To change to ITU
Q933 Annex A LMIs, include the
