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
# Create tunnel policy seq-lsp-te.
<PE1> system-view
[PE1] tunnel-policy seq-lsp-te
# Specify the tunnel selection order and set the number of tunnels for load balancing to 1—no load
balancing.

Preferred tunnel and tunnel selection order configuration
example
Network requirements
PE 1 has multiple tunnels to reach PE 2: two MPLS TE tunnels on the interface Tunnel 1 and Tunnel
3, and one LDP LSP tunnel.
PE 1 has multiple MPLS VPN instances: vpna, vpnb, vpnc, vpnd, and vpne. Table 11 shows the
tunnel policy that PE 1 uses for each VPN instance.
Table 11 Tunnel policies used for VPN instances
vpna, vpnb Use MPLS TE tunnel Tunnel1 as the preferred tunnel.
vpnc, vpnd Use MPLS TE tunnel Tunnel3 as the preferred tunnel.
vpne Uses one tunnel selected in LDP LSP-MPLS TE order.
