MPLS Concepts YES LAB Identifying MPLS Applications YES LAB wwwveslabnet Outline — Overview — What ApplicationsAre Used with MPLS? — What Is UnicastIP Routing? ffL1$ihIEhF5MPLS — What Is Multicast IP Routing? YES LAB - What are MPLSVPNs? - What Is MPLSTE - What Is MPLSQoS? - WhatisAToM? ffLZMPLS VPN? ff-a,ZMPLS TE ffLZMPLS QOS? ffLZAToM? — What Are the Interactions Between MPLS Applications? — Summary wwwveslabnet MPLS Applications YES LAB — MPLS is already used in many differentapplications: • Unicast IProuting • Multicast IProuting • MPLSTE . QoS MPLS VPNs (coursefocus) • AToM MPLS TE MPLS VPN wwwveslabnet MPLS Multicast IP Routin YES LAB — MPLS can also support multicast IP routing: A dedicated protocol is not needed to support multicast traffic across an MPLS • Cisco Protocol Independent Multicast Version 2 with extensions for MPLS is used to propagate routing information and labels. • The FEC is equal to a destination multicastaddress stored in the multicast routingtable. — wwwveslabnet Summary(cont.) YES LAB — MPLS TE supports constraints-based routing. MPLS MPLS QoS extends unicast IP routingand provides differentiated services. MPLS QoSffhgulPN6ffi, — AToM transports Layer 2 trafficover an IP or MPLS backbone. — Some MPLS applications may use a different routingand label exchange protocol; however, the applications all use the same label-forwarding engine. 2Ufij,
