Traffic policing, traffic shaping are key factors in implementing QoS. Traffic policing controls the rate of incoming packets to ensure that network resources are properly allocated. Traffic shaping controls the rate of outgoing packets to allow the traffic rate to match that on the downstream device. These factors work together to provide QoS guarantees on …

Networking Requirements The Level 1 carrier and the Level 2 carrier are in the same AS. The Level 2 carrier provides the BGP/MPLS IP VPN service for its customers. In Figure 1: PE1 and PE2 are PEs of the Level 1 carrier’s backbone. CE1 and CE2 belong to the Level 2 carrier and access the backbone …
Continue reading Configuring the Carrier’s Supporting Carrier in the Same ASHere we can find an example on how to configure the second carrier to provide BGP/MPLS IP VPN services when first carrier and the second carrier are in different ASs. Networking Requirements As shown in Figure 1, the Level 1 carrier and the Level 2 carrier are in different ASs. The Level 2 carrier provides BGP/MPLS …
Continue reading Configuring the Carrier’s Supporting Carrier (Inter-AS)A customer of an SP providing the BGP/MPLS IP VPN service may also be an SP. In this case, the SP providing the BGP/MPLS IP VPN service is called the provider carrier or the first carrier; the customer is called the customer carrier or the second carrier, as shown in Figure 1. This networking model is …

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 HoVPNIn this example, by configuring a VRRP backup group in load balancing mode, you can provide the mutual backup function to devices in the VRRP backup group and balance network traffic among these devices. 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 …

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 …
