mpls ldp autoconfig
MP-209
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
Usage Guidelines • You can specify this command multiple times to enable LDP on different routing areas with
interfaces running OSPF.
• If LDP is disabled globally, the mpls ldp autoconfig command fails. LDP must be enabled globally
by means of the global mpls ip command first.
• If the mpls ldp autoconfig command is configured, you cannot issue the global no mpls ip
command. If you want to disable LDP, you must issue the no mpls ldp autoconfig command first.
• The mpls ldp autoconfig command is supported only with OSPF and IS-IS interior gateway
protocols (IGPs).
• The MPLS LDP Autoconfiguration feature supports IS-IS only in Cisco IOS Release 12.0(32)SY.
• For interfaces running IS-IS processes, you can enable Multiprotocol Label Switching (MPLS) for
each interface using the router mode command mpls ldp autoconfig or mpls ldp igp autoconfig at
the interface level.
• For IS-IS interfaces, the level for which an interface is configured must be compatible with the level
for which autoconfiguration is desired.
• For IS-IS interfaces, each application of the configuration command overwrites the earlier
configuration. If initial autoconfiguration is enabled for level-1 and a later configuration specifies
level-2, LDP is enabled only on IS-IS level-2 interfaces.
Examples In the following example, MPLS LDP Autoconfiguration is enabled for OSPF area 5:
Router(config-router)# mpls ldp autoconfig area 5
