VPLS is an L2VPN technology based on MPLS and Ethernet technologies. VPLS can provide the multipoint-to-multipoint VPN services, which is better than the earlier point-to-point L2VPN services, and L3VPN services requiring carriers to manage the routing information. In the drafts relevant to VPLS, two VPLS network architectures are proposed: VPLS with PWs logically fully meshed …

It terminates the L2VPN and connects the L3VPN on a SR by creating a Virtual Ethernet group (VE-group). PW redundancy is configured to protect PWs on the L2VPN and VPN FRR is configured to protect links …

What mechanism does MPLS adopt to implement data forwarding? l MPLS includes two plane: control plane and data plane. l Control plane’s charge is to generate and maintain routing information and label information. Data plane’s charge is conventional IP packet …
Continue reading MPLS StructureHello guys , as we said before we will start configuring IPRAN , the first thing that you need after you configure the routing Protocol ” we already configure the ISIS before ” but we will configure it again here also , we will start the MPLS configuration on the network . As shown …
Continue reading IPRAN configuration Step by Step MPLS TE ConfigurationPurpose In a traditional IP network, a node select the shortest path as the route regardless of other factors such as bandwidth. The shortest path, however, may be congested with traffic, whereas other available paths are idle. Figure 1 Problems in Traditional Routing As shown in Figure 1, assume that links have the same metric. …
