Hello everyone,

There are two next-hops under one destination network in the routing table, and MPLSmpls labels are distributed to both routes, and I can view both LSP by executing command display MPLS LSP, but why the traffics are forwarded to only one LSP rather than load balance on the two LSP?

Please help me! Thank you!

Hello mate!

Please, try to enable load-balance for VPN-instance in BGP

bgp 100
ipv4-family vpn-instance VPN-X
maximum load-balancing ibgp 2

Also, for the tunnel, you can select the tunnel selection sequence and number of tunnels to be used.

tunnel-policy LSP
tunnel select-seq cr-lsp lsp gre load-balance-number 2 unmix

System-view
ip vpn-instance VPN-X
ipv4-family
tnl-policy LSP

the default load-balancing is based on flow, this wouldn't forward packets to each links in the load-balance group. if you want do that, you can change the load-balancing to packet based by command load-balance packet under system-view.

by the way, not only the MPLS links, but also the physical links, load-balancing is flow based by default.
