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

Configuring LDP MD5 Authentication
LDP MD5 authentication provides protection against spoofed TCP segments that can
be introduced into the connection streams for LDP sessions. Authentication is configurable
for both directly connected and targeted peers.
