The value of tmnxOspfLdpSyncAdminState specifies whether the IGP-LDP
synchronization feature is enabled or disabled on all interfaces
participating in the OSPF routing protocol.
When the value is set to 'disabled', IGP immediately advertises the
actual value of the link cost for all interfaces which have the IGP-LDP
synchronization enabled if the currently advertized cost is different.
IGP-LDP synchronization for all interfaces is then disabled.
