Tunnel selection order configuration example

Network requirements

PE 1 has multiple tunnels to reach PE 2: one MPLS TE tunnel on the interface Tunnel 1, and one LDP LSP tunnel.

Only one MPLS VPN, vpna, exists on PE 1. Select only one tunnel in LDP LSP-MPLS TE order for this VPN.

Configuration procedure

  1. Create tunnel policy seq-lsp-te, specify the tunnel selection order, and set the number of tunnels for load balancing to 1—no load balancing.

    <PE1> system-view
    [PE1] tunnel-policy seq-lsp-te
    [PE1-tunnel-policy-seq-lsp-te] select-seq lsp cr-lsp load-balance-number 1
    [PE1-tunnel-policy-seq-lsp-te] quit 
    
  2. Create MPLS VPN instance vpna, and apply tunnel policy seq-lsp-te to it.

    [PE1] ip vpn-instance vpna
    [PE1-vpn-instance-vpna] route-distinguisher 100:1
    [PE1-vpn-instance-vpna] vpn-target 100:1
    [PE1-vpn-instance-vpna] tnl-policy seq-lsp-te
