Tunnel policy configuration examples
219BExclusive tunnel configuration example
439BNetwork requirements
PE 1 has multiple tunnels to reach PE 2: two MPLS TE tunnels on interface Tunnel 1 and 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 1, and the VPN vpnb exclusively uses the MPLS TE tunnel 2.
440BConfiguration 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 2 as the preferred tunnel.
[PE1] tunnel-policy preferredte2
[PE1-tunnel-policy-preferredte2] preferred-path tunnel 2
[PE1-tunnel-policy-preferredte2] quit
2. Configure MPLS VPN instances and apply tunnel policies 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 preferredte2 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 preferredte2
