Configuration procedure
1.
Configure tunnel policies on PE 1:
# Create tunnel policy preferredte1, and configure tunnel 1 as the preferred tunnel.
<PE1> system-view
[PE1] tunnel-policy preferredte1
[PE1-tunnel-policy-preferredte1] preferred-path tunnel 1
[PE1-tunnel-policy-preferredte1] quit
# Create tunnel policy preferredte2, and configure tunnel 3 as the preferred tunnel.
[PE1] tunnel-policy preferredte2
[PE1-tunnel-policy-preferredte2] preferred-path tunnel 3
[PE1-tunnel-policy-preferredte2] quit
# Create tunnel policy select-lsp, configure the policy to select only one tunnel in LDP LSP-MPLS TE
order, and set the number of tunnels for load balancing to 1—no load balancing.
[PE1] tunnel-policy select-lsp
[PE1-tunnel-policy-select-lsp] select-seq lsp cr-lsp load-balance-number 1
[PE1-tunnel-policy-select-lsp] quit
2.
Configure MPLS VPN instances and apply tunnel policies to the VPN instances:
# Create MPLS VPN instances vpna and vpnb, and apply tunnel policy preferredte1 to them.
[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 preferredte1
[PE1-vpn-instance-vpna] quit
[PE1] ip vpn-instance vpnb
[PE1-vpn-instance-vpnb] route-distinguisher 100:2
[PE1-vpn-instance-vpnb] vpn-target 100:2
[PE1-vpn-instance-vpnb] tnl-policy preferredte1
[PE1-vpn-instance-vpnb] quit
# Create MPLS VPN instances vpnc and vpnd, and apply tunnel policy preferredte2 to them.
[PE1] ip vpn-instance vpnc
[PE1-vpn-instance-vpnc] route-distinguisher 100:3
[PE1-vpn-instance-vpnc] vpn-target 100:3
[PE1-vpn-instance-vpnc] tnl-policy preferredte2
[PE1-vpn-instance-vpnc] quit
[PE1] ip vpn-instance vpnd
[PE1-vpn-instance-vpnd] route-distinguisher 100:4
[PE1-vpn-instance-vpnd] vpn-target 100:4
[PE1-vpn-instance-vpnd] tnl-policy preferredte2
[PE1-vpn-instance-vpnd] quit
