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 …

A 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 ConnectionVPLS 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 …

As shown …

Figure 1 BGP operating modes Roles in Transmitting BGP Messages …
