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:
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."
