LDP assumes that the label manager is up and running. LDP aborts initialization if the label manager is not running. The label manager is initialized at system boot-up; therefore anything that causes it to fail likely indicates that the system is not functional. The 7705 SAR uses a label range from 28 672 (28K) to 131 071 (128K-1) to allocate all dynamic labels, including VC labels.
