WebHow MPLS Affects Frame Size. MPLS changes the way traffic is forwarded by adding labels to packets. Each label is four bytes long, and you may have a stack of several labels. The labels are added between the Ethernet header and the IP header. The result is that the IP packet size does not change, but the Ethernet frame size does. WebLDP is a protocol that automatically generates and exchanges labels between routers. Each router will locally generate labels for its prefixes and will then advertise the label values to its neighbors. It’s a standard, based on Cisco’s proprietary TDP (Tag Distribution Protocol). It’s pretty much the same story as 802.1Q/ISL or PaGP/LACP.
WebThere are four type table that is related to Multi Protocol Label Switching.This tables are formed with CEF (Cisco Express Forwarding) mechanism and the Label Distribution Protocols.So what are the tables used in MPLS?
