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, 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
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
