IPv6 MPLS L3VPN configuration task list

By configuring basic IPv6 MPLS L3VPN, you can construct a simple IPv6 VPN network over an MPLS
backbone.
To deploy special IPv6 MPLS L3VPN networks, such as inter-AS VPN, you must also perform specific
configurations in addition to the basic IPv6 MPLS L3VPN configuration. For more information, see the
related sections.

Configuring basic IPv6 MPLS L3VPN

The key task in IPv6 MPLS L3VPN configuration is to manage the advertisement of IPv6 VPN routes on the
MPLS backbone, including management of PE-CE route exchange and PE-PE route exchange.
