Tunnel policy configuration examples
Preferred tunnel 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.
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.
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 the interface Tunnel 1, and one LDP LSP
tunnel.
One MPLS VPN vpna exists on PE 1. The VPN exclusively uses the MPLS TE tunnel.
