MPLS has become very popular during recent years to accommodate gigabit switching speeds over wide area networks. Traditional IP routing uses enormous processing overhead and slows down packet switching speeds. MPLS allows packets to be forwarded by looking at the label (Just like switch looks at Layer 2) rather than having to be passed up to Layer 3 (the IP header). Each packet gets labeled on entry into the service provider’s MPLS network by the ingress router. All the subsequent routing between nodes is based only on the MPLS label that was attached by the previous MPLS enabled router. The router doesn’t have to look at IP header, thus saving enormous processing load. Alter the packet traverses though the MPLS network, the egress router removes the label(s) and forwards the original IP packet toward its final destination.
Network Simulator with Designer for CCNA has been updated to include MPLS commands and several MPLS labs. For complete list of labs included, please visit the page here:
