R21xx-HP FlexFabric 11900 MPLS Configuration Guide

Configuring tunnel policies

Overview

Tunnel policies enable a PE to forward traffic for each MPLS VPN over multiple LSP tunnels to achieve

load sharing when the PE has multiple tunnels to the peer PE.

For more information about MPLS VPNs, see "Configuring MPLS L3VPN."

Configuring a tunnel policy

To select multiple tunnels for load sharing, create a tunnel policy and specify the number of tunnels by

using the select-seq load-balance-number command.

As shown in Figure 25, P

E 1 and PE 2 have three tunnels in between and they connect to multiple MPLS

VPNs. To achieve load sharing over the three tunnels for each VPN, configure one tunnel policy, use the

select-seq load-balance-number command to specify the number of tunnels for load balancing as three,

and apply the tunnel policy to each MPLS VPN.
