Apply an export routing policy 
to the current VPN instance 

export route-policy 
route-policy 

Optional 

By default, all VPN instance 
routes permitted by the export 
target attribute can be 
redistributed. 

 

z 

A single vpn-target command can configure up to eight VPN targets. You can configure up to 20 

VPN targets for a VPN instance. 

z 

You can define the maximum number of routes for a VPN instance to support, preventing too many 

routes from being redistributed into the PE.  

z 

Before associating a routing policy with a VPN instance, you must create the routing policy at first. 

Otherwise, the default routing policy is used. 

 

Follow these steps to configure a tunneling policy: 

Enter system view 

— 

Create a tunneling policy and 
enter tunneling policy view 

tunnel-policy 
tunnel-policy-name 

Required 

Specify the priorities of tunnels 
and the number of tunnels for 
load balancing 

tunnel select-seq { cr-lsp | 
lsp } * load-balance-number 
number 

Required 

By default, the LSP tunnel is 
used and the number of tunnels 
for load balancing is 1. 

 

z 

When you configure tunnel priorities using the tunnel select-seq command, a tunnel type closer to 

the select-seq keyword has a higher priority. For example, with the tunnel select-seq  lsp gre 

load-balance-number 1 command configured, VPN uses a GRE tunnel if no LSP exists. Once an 

LSP is created, the LSP tunnel is used instead. 

z 

If you specify more than one tunnel type and the number of tunnels of a type is less than the 

specified number of tunnels for load balance, tunnels of different types may be used.
