Core MPLS
Interface
ML-Series Card A
with MPLS-TE Tunnel
Purpose
Configures an interface type and enters interface configuration
mode.
Gives the tunnel interface an IP address.
An MPLS-TE tunnel interface should be unnumbered because it
represents a unidirectional link.
Specifies the destination for a tunnel.
Sets the tunnel encapsulation mode to MPLS-TE.
Specifies IGP should use the tunnel (if the tunnel is up) in its
enhanced shortest path first (SPF) calculation.
Configures the bandwidth for the MPLS-TE tunnel.
Configures the tunnel to use a named IP explicit path or a dynamic
path.
