Configuration Guide.

 

7. 

Apply a tunnel policy to 
the VPN instance. 

tnl-policy tunnel-policy-name

 

By default, only one tunnel is 
selected (no load balancing) in 
this order: LSP tunnel, GRE 
tunnel, and CR-LSP tunnel. 

The specified tunnel policy must 
have been created. 

For information about tunnel 
policies, see "

Configuring routing between a PE and a CE 

You can configure static routing, RIP, OSPF, IS-IS, EBGP, or IBGP between a PE and a CE. 

Configuring static routing between a PE and a CE 

Step

VPN 

instance.

By default, no  static route is 
configured for a VPN 
instance.  

Perform this configuration on 
the PE. On the CE, configure 
a common static route. 

For  more  information about 
static routing, see 

Layer 

3—IP Routing Configuration 
Guide

. 

 

Configuring RIP between a PE and a CE 

A RIP process belongs to the public network or a single VPN instance. If you create a RIP process 
without binding it to a VPN instance, the process belongs to the public network. 

To configure RIP between a PE and a CE: 

 

Step 

Command 

Remarks 

1. 

Enter system view. 

system-view 

N/A 

2. 

Create  a  RIP  process  for a 
VPN instance and enter RIP 
view. 

rip 

[ 

process-id 

]

  vpn-instance

 

vpn-instance-name

 

Perform this configuration on the 
PE. On the CE, create a common 
RIP process. 

3. 

Enable RIP on the interface 
attached to the specified 
network. 

network network-address

 

By default, RIP is disabled on an 
interface. 

 

Configuring OSPF between a PE and a CE 

An  OSPF process that is  bound to a  VPN  instance does  not use the public network router ID 
configured in system view. Therefore, you must specify a router ID when starting a process or 
configure an IP address for at least one interface of the VPN instance. 

An OSPF process belongs to the public network or a single VPN instance. If you create an OSPF 
process without binding it to a VPN instance, the process belongs to the public network.
