Configuring route related attributes for a VPN instance

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:

    1. ip vpn-instance vpn-instance-name

    2. 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.

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.

7. Apply a tunnel policy to the VPN instance.

tnl-policy tunnel-policy-name

By default, only one tunnel is selected (no load balancing). The LSP tunnel takes precedence over the CR-LSP tunnel.

The specified tunnel policy must have been created.

For information about tunnel policies, see "Configuring tunnel policies."
