To configure LDP autoconfiguration to ensure that LDP is configured on all interfaces
running the IGP:
■
Specify whether LDP is created automatically on the current interface or all
interfaces:
■
Create LDP on all interfaces in the IGP router context
host1(config)# router ospf 1
host1(config-router)# mpls ldp autoconfig area 1
■
Create LDP on the current interface
host1(config)# interface atm 2/0
host1(config-if)# mpls ldp isis autoconfig

Configuring LDP-IGP Synchronization
MPLS data packets can be discarded in a network when the network IGP is operational
on a link for which LDP is not fully operational, because there is no coupling between
the LDP operational state and the IGP. When LDP is not fully operational, LDP is
considered to not be synchronized with the IGP.
To configure LDP-IGP synchronization:
1.
Specify whether LDP is synchronized with the IGP on the current interface or all
interfaces.
■
Synchronize LDP with the IGP on the current interface:
host1(config)# interface atm 2/0
host1(config-if)# mpls ldp isis sync
■
Synchronize LDP with the IGP on all interfaces in the IGP router context:
host1(config)# router ospf 1
host1(config-router)# mpls ldp ospf sync
2.
Specify how long the IGP waits to synchronize with LDP.
host1(config)# mpls ldp igp sync holddown 15
