Which of the following protocols uses label-switching routers and label-edge routers to forward traffic? contents of this label, without the need to examine the packet itself. router. This is a type of router located in the middle of a MPLS network. It is responsible for switching the labels used to route packets. When an LSR receives a packet, it uses the label included in the packet header as an index to determine the next hop on the label-switched path (LSP) and a corresponding label for the packet from a lookup table. The old label is then removed from the header and replaced with the new label before the packet is routed forward. exit points for the network. LERs respectively, add an MPLS label onto an incoming packet and remove it off the outgoing packet. appropriate labels to be affixed, labels the packet accordingly, and then forwards the labelled packets into the
