Step Command

Remarks

2.

Enter VPN instance view or
IPv6 VPN view.

Enter VPN instance view:

ip vpn-instance
vpn-instance-name

Enter IPv6 VPN view:

a.

ip vpn-instance

vpn-instance-name

b.

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 supported.

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

By default, the maximum number of
active routes for the 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 CRLSP
tunnel.
The specified tunnel policy must
have been created.
For information about tunnel

policies, see "

Configuring tunnel

policies
