A CE must advertise its VPN
routes to the connected PE so
that the PE can advertise them
to the peer CE.
Configuring IBGP between a PE and a CE
Use IBGP between PE and CE only in a basic IPv6 MPLS L3VPN network. In networks such as
inter-AS VPN and carrier's carrier, you cannot configure IBGP between PE and CE.
