Configuring Load Balancing Among EBGP and IBGP Routes When CEs Are Dual-Homed When a CE is dual homed to two PEs, if one PE is in the same AS as the remote PE, whereas the other PE is not in the same AS as the remote PE, you can configure EBGP and IBGP route load …

Hierarchy Of VPN – HoVPN Hierarchical Model and Plane Model On a BGP/MPLS IP VPN, as the key devices, PEs perform the following functions: PEs ensure the access for users, and thus require a great number of interfaces. PEs manage and advertise VPN routes, and process user packets. Thus, the PEs require large-capacity memory and …
Continue reading Hierarchy Of VPN – HoVPNA local CCC connection refers to the connection between two local CEs, that is, two CEs connected to the same PE. Similar to a Layer 2 switch, the PE can switch traffic without the need to set up a static LSP. Networking Requirements Figure 1 shows the CE is connected with the PE through a POS …
Continue reading Configure a CCC Local ConnectionThis 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 As shown in Figure 1, two routers, PE1 and PE2, are PEs to be enabled with the VPLS function. CE1 is connected with PE1, while CE2 is connected with PE2. CE1 and CE2 belong to the same VPLS. After the VPLS configuration, interworking between CE1 and CE2 is available. In the network, construct a …
Continue reading Configuring Martini VPLSVPLS 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 …
Continue reading Basic Principles of VPLSNetworking 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 …
