R0106-HP MSR Router Series MPLS Command Reference(V7)

Usage guidelines
For a traffic trunk from a CT, the setup or/and holding priority of the LSP transporting the traffic trunk must
be the priority specified for the CT in the TE class.
When you configure a TE class, make sure to specify a CT-priority pair different from that in any existing
TE class.
When you restore the default settings for a TE class, make sure the default CT-priority pair is different from
the CT-priority pair of an existing TE class.
After a TE class is modified, the device performs the following tasks:
1. Notifies the IGP to re-advertise the bandwidth information for all TE interfaces.
2. Removes and then reestablishes the CRLSPs of the TE class on all TE interfaces.
Examples
# Specify CT 2 and priority 3 for TE class 7 in IETF DS-TE mode.

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.
