Usage guidelines

The prestandard and IETF modes of DS-TE have the following differences:

• The prestandard mode supports two CTs (CT 0 and CT 1), eight priorities, and up to 16 TE classes.

The IETF mode supports four CTs (CT 0 through CT 3), eight priorities, and up to eight TE classes.

• The prestandard mode does not allow you to configure TE classes. The IETF mode allows for TE class

configuration.

• The prestandard mode supports only RDM. The IETF mode supports both RDM and MAM.

• A device operating in prestandard mode cannot communicate with devices from some vendors. A

device operating in IETF mode can communicate with devices from other vendors.

Be aware of these differences and choose a proper DS-TE mode as needed.

After the DS-TE mode is changed, all CRLSPs on the device are deleted and then re-established.
