View Tunnel interface view

Parameter bandwidth: Total bandwidth that the bypass tunnel (also called the protection tunnel) can protect, in the range 1 to 32000000 kbps.

bc0: Indicates that only the LSPs using BC0 bandwidth (global bandwidth) can use the bypass tunnel.

bc1: Indicates that only the LSPs using BC1 bandwidth (subpool bandwidth) can use the bypass tunnel.

If neither BC0 nor BC1 is specified, all LSPs can use the bypass tunnel.

un-limited: Puts on limit on total protected bandwidth.

Description Use the mpls te backup bandwidth command to configure the total bandwidth and type of LSP that the bypass tunnel can protect.

Use the undo mpls te backup bandwidth command to remove the configuration.

By default, bypass tunnels do not protect bandwidth.

If neither BC0 nor BC1 is specified, all LSP can use the bypass tunnel.

n This command is not supported when the signaling protocol is CR-LDP.
