Configuring a static MPLS TE tunnel can implement setup of static CR-LSPs. The configuration is simple. Labels are allocated manually and control packets do not need to be exchanged, so static LSPs consume less resources.
Before configuring a static MPLS TE tunnel, complete the following tasks:
Configure an LSR ID on each LSR.
Enable basic MPLS functions on each LSR globally and on each interface.
After a static CR-LSP is bound to a tunnel interface, the static CR-LSP takes effect without an IP route configured.
