Step Command
Remarks
1.
Enter system view.

N/A
2.
Enter VPN instance view or
VPN instance IPv6 VPN
view.
•
Enter VPN instance view:
ip vpn-instance
vpn-instance-name
•
Enter VPN instance 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 VPN instance
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.
routing-table
limit
number
{
warn-threshold
|
simply-alert
}
By default, the number of active
routes in 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.
