LDP over TE can be enabled on the ingress of a TE tunnel.
In LDP over TE networking, load balancing is supported when the ingress node of a TE tunnel is an S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-HI, S6730S-H, or S6730-H. When there are multiple TE tunnels or there are both TE tunnels and LDP tunnels in the MPLS TE domain, LDP LSP service traffic can be load balanced among multiple tunnels. To adjust the load balancing mode, see (Optional) Configuring the Load Balancing Mode for Packet Forwarded Through LSPs.
