Tunnel selection order configuration example

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

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

# Create tunnel policy seq-lsp-te-gre.

<PE1> system-view
[PE1] tunnel-policy seq-lsp-te-gre

# Specify the tunnel selection order, and set the number of tunnels for load balancing to 1—no load balancing.

[PE1-tunnel-policy-seq-lsp-te-gre] select-seq lsp cr-lsp gre load-balance-number 1
[PE1-tunnel-policy-seq-lsp-te-gre] quit

# Create MPLS VPN instance vpna, and apply tunnel policy seq-lsp-te-gre to it.
