Field Description
AUTOCONFIG
In
formation
LDP enabled—Indicates whether LDP autoconfiguration is enabled on this
interface. Value is YES or NO.
SYNC Information Provides synchronization information.
• Required—Indicates whether synchronization is required on the
interface.
• Achieved—Indicates whether synchronization was achieved with LDP.
If IS-IS was configured on an interface but synchronization is not
achieved, the Achieved field indicates NO. The Required field still
indicates YES.
• IGP Delay—Indicates whether the IS-IS process must wait for
synchronization with LDP before bringing up the interface adjacency.
• Holddown time—Valid values are Finite or Infinite. The finite value is
equal to the hold-down delay that you configured using the mpls ldp igp
sync holddown command. If this field indicates Infinite, hold-down time
was not configured. Therefore, IS-IS waits until synchronization is
achieved before bringing adjacency UP.
The Holddown time field is significant only if the IGP Delay field indicates
YE
S.
• State—Indicates information about the state of synchronization on the
interface. If synchronization is achieved, the output shows the following:
– SYNC achieved—Synchronization was required and has been
achieved.
If synchronization is not achieved, the output shows one of the
f
ollowing:
– Holding down until SYNC—No hold-down timer was configured, so
IS-IS continues to hold down adjacency until synchronization is
achieved.
– Holding down with timer—A hold-down timer was configured and
IS-IS is holding down adjacency until the timer, indicated in the IGP
Delay field, expires.
– Maximum metric in effect—Although synchronization was not
achieved, the IGP brought up adjacency with the maximum metric.
Command Description
mpls ldp autoconfig Globally enables LDP autoconfiguration on all interfaces that belong to an
OSPF or
IS-IS process.
mpls ldp sync Enables MPLS LDP-IGP synchronization on
interfaces for an OSPF process
or an IS-IS process.
