The MPLS LDP
IGP Synchronization feature ensures that LDP is fully established before the
IGP path is used for switching.
In 12.0(30)S,
this feature was introduced.
In
12.0(32)SY, support for enabling synchronization on interfaces running
Intermediate System-to-System (IS-IS) processes was added.
In
12.2(33)SB, the feature was integrated. MPLS LDP IGP synchronization for IS-IS
is not supported in this release.
In
12.2(33)SRB, the feature was integrated. MPLS LDP IGP synchronization for IS-IS
is not supported in this release.
In 15.1(1)SY,
support for configuring MPLS LDP IGP synchronization with OSPF and IS-IS
interfaces was enabled.
In Cisco IOS XE Release 2.5, support for configuring MPLS LDP
IGP synchronization with IS-IS interfaces was implemented on Cisco ASR 1000
Series Routers.
In Cisco IOS XE Release 3.6S, support for configuring MPLS LDP
IGP synchronization was added for the Cisco ASR 903 Router.
The following
commands were modified:
debug mpls ldp igp
sync,
mpls ldp igp
sync,
mpls ldp igp sync
holddown,
mpls ldp sync,
show ip ospf mpls ldp
interface,
show isis mpls
ldp, and
show mpls ldp igp
sync.
