Configuring 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 …

Networking Requirements As shown in Figure 1. CX-A serves as the master CX device of backup group 1 and the backup CX device of backup group …
Continue reading Configuring VRRP in Load Balancing ModeThe Virtual Router Redundancy Protocol (VRRP) is a fault tolerant protocol, and it groups several routers into a virtual router. If the next hop router of a host is defective, VRRP uses a mechanism to switch traffic to another router. This ensures continuity and reliability of communications. In this example, by configuring a VRRP backup group in master/backup mode, …
Continue reading Configuring VRRP in Master/Backup ModeBGP Path Selection Algorithm Border Gateway Protocol (BGP) routers typically receive multiple paths to the samedestination. The BGP best path algorithm decides which is the best path toinstall in the IP routing table and to use for traffic forwarding. How the Best Path Algorithm Works BGP assigns the first valid path as the …

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 …
