IS-IS Traffic Engineering (TE) is an extension of IS-IS to support MPLS TE. As specified in RFC 5305 and RFC 4205, IS-IS TE defines new TLVsand sub-TLVs in IS-IS LSPs to carry TE information, floods LSPs to implement the flooding and synchronization of TE information, and transmits TE information to the CSPF module. IS-IS TE supports MPLS …

Networking Requirements The integrated L2VPN access to L3VPN solution allows Ethernet NodeBs to communicate with Radio Network Controllers (RNCs). 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 …
Continue reading Configuring an Integrated IP RAN (PWE3 + L3VPN) with Ethernet NodeBsl MPLS network forwards packet according to the label. But how does label be generated? 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. …
