IBM 6 MPLS manual 6 Configuring TE Bindings

Specialized Models User Guide 6 MPLS Model User Guide

When an unlabeled packet arrives at an ingress LER, the following sequence occurs to determine the correct label for the packet:

1)The TE binding is selected based on the packet FEC and the incoming interface.

2)The packet is checked to make sure that its traffic characteristics conform to those specified for the TE binding’s traffic trunk.

3)The packet is labeled for and sent through the primary LSP specified for the TE binding.

This weight attribute configuration uses LER2-LER5 75% of the time and LER2-site9 25% of the time.

•EXP <--> Drop Precedence and EXP <--> PHB These attributes specify which mappings, defined in the MPLS configuration object, are used by the router.

•LDP Parameters—specifies Label Distribution Protocol parameters used by the LSR. LDP Parameters is a compound attribute, composed of the following sub-attributes:

—Discovery Configuration—specifies Hello message parameters needed to learn of neighboring routers

—Session Configuration—specifies Keep-alive message parameters used to establish LDP sessions

—Recovery Configuration—specifies how node and link failures are detected
