Tunnel policy configuration examples

Preferred tunnel configuration example

Network requirements
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.
Two MPLS VPN instances, vpna and vpnb, exist on PE 1. Configure PE 1 to use the MPLS TE
tunnel to forward traffic for both VPNs.
Configuration procedure
1. Create a tunnel policy named 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
2. Configure MPLS VPN instances and apply the tunnel policy to the VPN instances:
# Create MPLS VPN instance vpna, and apply tunnel policy preferredte1 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 preferredte1
[PE1-vpn-instance-vpna] quit
# Create MPLS VPN instance vpnb, and apply tunnel policy preferredte1 to it.
[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

Exclusive tunnel configuration example

Network requirements
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.
Two MPLS VPNs, vpna and vpnb, exist on PE 1. The VPN vpna exclusively uses the MPLS TE
tunnel, and the VPN vpnb exclusively uses the GRE tunnel.
Configuration procedure
1. Configure tunnel policies on PE 1:
Command
display mpls tunnel { all | statistics | [ vpn-instance
vpn-instance-name ] destination { tunnel-ipv4-dest | tunnel-ipv6-dest } }
