Then, the ingress PE advertises the VPN-IPv6 routes to the egress PE through MP-BGP.
Finally, the egress PE compares the export target attributes of the VPN-IPv6 routes with the import target
attributes that it maintains for the VPN instance and, if they are the same, adds the routes to the routing
table of the VPN instance.
The PEs use an IGP to ensure the connectivity between them.
Routing information exchange from the egress PE to the remote CE
The exchange of routing information between the egress PE and the remote CE is the same as that
between the local CE and the ingress PE.

Basic IPv6 MPLS L3VPN configuration task list

The key task in IPv6 MPLS L3VPN configuration is to manage the advertisement of IPv6 VPN routes on the
MPLS backbone, including PE-CE route exchange and PE-PE route exchange.
Complete the following tasks to configure basic IPv6 MPLS L3VPN:
Task
Configuring VPN instances
Remarks
By configuring basic IPv6 MPLS L3VPN, you can
construct simple IPv6 VPN networks over an MPLS
backbone.
To deploy special IPv6 MPLS L3VPN networks, such as
inter-AS VPN, you must perform some specific
configurations in addition to the basic IPv6 MPLS
L3VPN configuration. See the related sections for
details.
