INETWORK MAC VERIFICATION
Xconnect 192.168.22.22 455 encapsulation mplsĬonfigurations Verification Checking MPLS link on PE1 and PE2 The PE router updates the header, if necessary, and sends the packet out the appropriate interface to the destination switch.Īllows all traffic on a port to share a single VC across an MPLS network The PE router also removes the VC label from the packet. The network core routers use the LSP tunnel label to move the packet through the MPLS backbone and do not distinguish Ethernet traffic from any other types of packets in the MPLS backbone.Īt the other end of the MPLS backbone, the egress PE router receives the packet and de-encapsulates the packet by removing the LSP tunnel label if one is present.

The ingress PE router adds a point-to-point virtual connection (VC) label and a label switched path (LSP) tunnel label for normal MPLS routing through the MPLS backbone. The rest of the packet header is not changed. The ingress PE router receives an Ethernet frame and encapsulates the packet by removing the preamble, the start of frame delimiter (SFD), and the frame check sequence (FCS). Each frame is transported as a single packet, and the PE routers connected to the backbone add and remove labels as appropriate for packet encapsulation EoMPLS encapsulates ethernet frames in MPLS packets and forwards them across the MPLS network.
