ct3: Indicates that only the LSPs of CT 3 can use the bypass tunnel.
un-limited: Puts on limit on total protected bandwidth.
Examples
# Configure Tunnel 0 to provide protection for LSPs of CT 0 without constraining the bandwidth to be
protected. Configure Tunnel 1 to provide protection for LSPs of CT 1 and protect up to 1000 kbps
bandwidth.

mpls te bfd enable
Description
Use the mpls te bfd enable command to configure BFD to check the connectivity of the MPLS TE tunnel.
Use the undo mpls te bfd enable command to disable BFD for the MPLS TE tunnel of a TE tunnel interface.
By default, BFD is not configured for MPLS TE tunnels.
Enable LSP verification by using the mpls lspv command first before executing the mpls te bfd enable
command. For details of the mpls lspv command, see the chapter “MPLS basics configuration
commands.”
BFD session parameters are those configured on the TE tunnel interface. The source address of the BFD
session is the MPLS LSR ID. Before enabling BFD for an MPLS TE tunnel, make sure that a route exists on
the peer device to the MPLS LSR ID. You can also configure the BFD session parameters on the tunnel
interface as needed. For information about BFD parameter configuration, see the High Availability
Configuration Guide.
