Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter VPN instance view or

IPv6 VPN view.

Enter VPN instance view:
ip vpn-instance

vpn-instance-name

Enter IPv6 VPN view:

address-family ipv6

Configurations made in VPN
instance view apply to both IPv4
VPN and IPv6 VPN.
IPv6 VPN prefers the
configurations in IPv6 VPN view

over the configurations in VPN
instance view.

3.

Configure route targets.

vpn-target vpn-target&<1-8>
[ both | export-extcommunity |

import-extcommunity ]

By default, no route targets are
configured.

4.

Set the maximum number of

active routes allowed.

routing-table limit number
{ warn-threshold | simply-alert }

By default, the number of active
routes allowed for a VPN instance
is not limited.
Setting the maximum number of
active routes for a VPN instance

can prevent the PE from storing too

many routes.

5.

Apply an import routing
policy.

import route-policy route-policy

By default, all routes matching the
import target attribute are
accepted.
Make sure the routing policy
already exists. Otherwise, the

device does not filter received
routes.
For information about routing
policies, see Layer 3—IP Routing

Configuration Guide.

6.

Apply an export routing
policy.

export route-policy route-policy

By default, routes to be advertised
are not filtered.
Make sure the routing policy
already exists. Otherwise, the

device does not filter routes to be

advertised.
For information about routing

policies, see Layer 3—IP Routing
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 and CR-LSP

tunnel.
The specified tunnel policy must
have been created.
For information about tunnel
policies, see "Configuring tunnel

policies."
