</p><p>Beim Eintritt eines IP-Paketes in eine MPLS-Domain wird die Routing-Information dazu genutzt, ein passendes MPLS-Label für das Paket auszuwählen, das Paket mit diesem Label zu versehen und innerhalb der MPLS-Domain weiterzuleiten.
</p><p>Beim Austritt eines IP-Paketes aus der MPLS-Domain entfernt der LER das MPLS-Label und leitet das IP-Paket entsprechend dem zugrundeliegenden IP-Routing-Mechanismus weiter.
