Glossary
carrier supporting carrier --A situation where one service provider allows another service provider to use
a segment of its backbone network. The service provider that provides the segment of the backbone
network to the other provider is called the backbone carrier. The service provider that uses the segment of
the backbone network is called the customer carrier.
CE router --customer edge router. A router that is part of a customer network and that interfaces to a
provider edge (PE) router.
inbound label binding filtering --Allows LSRs to control which label bindings it will accept from its
neighboring LSRs. Consequently, an LSR does not accept or store some label bindings that its neighbors
advertise.
label --A short fixed-length identifier that tells switching nodes how to forward data (packets or cells).
label binding --An association between a destination prefix and a label.
