# Tunnel 0 provides protection for LSPs using BC0 bandwidth without protecting 
bandwidth. Tunnel 1 provides protection for LSPs using BC1 bandwidth and it can 
protect 1000 kbps bandwidth.

bc0: Obtains bandwidth from BC0.

bc1: Obtains bandwidth from BC1.

bandwidth: Bandwidth needed by the MPLS TE tunnel, in the range 1 to 
32000000 kbps.

Use the mpls te bandwidth command to assign bandwidth to the MPLS TE 
tunnel.

Use the undo mpls te bandwidth command to restore the default.

By default, no bandwidth is assigned to MPLS TE tunnels.

If neither the bc1 keyword nor the bc0 keyword is specified, bandwidth is 
assigned using the global bandwidth pool (BC0).
