1. The customer edge router will peer only with a provider router and will not peer with other customer edge routers. With reference to the diagram above, CE2 will peer with PE2 and not with CE1 or CE3.
2. If a new site is added, configuration is done only on the provider edge router. If site 4 is to be added in the peer model in figure 4, then only the PE router is to be configured. The other CE and PE routers need not be configured or modified.
3. The data packet contains the following information: Destination IP address, Class of Service (COS) and Quality of Service (QoS) information.
4. There are less network delays as there is no circuit established, and no maintenance and tear down process required.
5. Lower Cost: MPLS is layer 2.5 technology.
