Implementing MPLS Traffic Engineering
Purpose
Enters MPLS-TE configuration mode.
Enables traffic engineering on a specific
interface on the originating node.
Enables the creation of dynamic NHOP
backup tunnels. By default, both NHOP
and NNHOP protection are enabled.
Using this nhop-only option, only
Note
link protection is provided.
Enables the exclusion of SRLG values on
a given link for the AutoTunnel backup
associated with a given interface.
The preferred option allows the
AutoTunnel Backup tunnels to come up
even if no path excluding all SRLG is
found.
Configures attribute-set template for
auto-tunnel backup tunnels.
