NOTE:
Route related attributes configured in VPN instance view are applicable to both IPv4 VPNs and IPv6
VPNs.
You can configure route related attributes for IPv6 VPNs in both VPN instance view and IPv6 VPN view.
Those configured in IPv6 VPN view take precedence.
A single vpn-target command can configure up to eight VPN targets. You can configure up to 64 VPN
targets for a VPN instance.
You can define the maximum number of routes for a VPN instance to support, preventing too many
routes from being redistributed into the PE. The maximum number of routes supported by a PE varies by
device.
Create a routing policy before associating it with a VPN instance. Otherwise, the device cannot filter the
routes to be received and advertised.
Configure routing
To enable VPN route distribution, bind the interfaces between the MCE and the PE to the IPv6 instances,
perform routing configuration, and redistribute VPN routing information to the routing protocol running
between the MCE and PE.
NOTE:
The following operations are performed on the MCE. The PE is configured in the same way as it is
configured in a basic IPv6 MPLS L3VPN. For how to configure the PE, see the chapter “MPLS L3VPN
configuration”.
Configuring IPv6 static routing
Follow these steps to configure static routing between MCE and PE:
