The public network tunnel of a Martini VLL can be an MPLS TE tunnel. Networking Requirements As shown in Figure 1, CE1 and CE2 belong to the same VPN. They access the MPLS backbone network through PE1 and PE2 respectively. OSPF is used as the IGP protocol on the MPLS backbone network. In this scenario, you …

OSPF fast convergence is an extended feature of OSPF implemented to speed up the convergence of routes. It includes the following: I-SPF Incremental SPF (I-SPF) recalculates only the routes of the changed nodes rather than all the nodes when the network topology changes. This speeds up the calculation of routes. PRC Partial Route Calculation (PRC) …
Continue reading OSPF Fast ConvergenceConfiguring Hierarchy Of VPN – HoVPN We already explain the HoVPN before so now we will know how to configure it . Networking Requirements As shown in Figure 1: CE1 and CE2 belong to VPN-A and the VPN target is 1:1. CE1 accesses the backbone network through the UPE and CE2 accesses the network through the …
Continue reading Configuring HoVPNThis part describes how to configure a Martini VLL in IP interworking mode to access the L3VPN. Networking Requirements As shown in Figure 1, the NPE and PE2 serve as the PE of IP/MPLS backbone network, and the UPE works as the PE on the VLL access network. CE1 accesses the MPLS L3VPN on the IP/MPLS …
Continue reading Configuring a Martini VLL to Access an L3VPNNetworking 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 …
