Exclusive tunnel configuration example

Network 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.

Configuration procedure

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

Configure MPLS VPN instances and apply tunnel policies to the VPN instances:

# Create MPLS VPN instance

vpna

, and apply tunnel policy

preferredte1

to it.
