BGP routing load balancing fault caseNetwork Architecture 1. Topology: the actual network structure is simplified considering the privacy of the company's network and a clearer description of fault phenomena. 2. network planning and data Configuration Overview: ◆ ASR9K establishes IBGP neighbor relationships with two n7ks Based on the interconnected addresses respectively; ◆ ASR9K is connected to the Cisco 752 architecture and 752 is used as the CDN server; ◆ the server gateways are both in the

SceneIn a production environment, we often separate one of the Nexus switches from VPC domain, such as upgrades or disaster preparedness drills. But one of the details is that Sticky Master 's state is rarely noticed, so this can lead to network outages.In a VPC environment, both vpcs perform role elections, with priority configuration, assuming that n7k-1 is primary , N7k-2 is secondary .Step OneWhen we se

Network equipment is also an important device in the network boundary. It is the main road to the entire data center and cannot cause any loss. In the past two days, the Nexus network equipment was reinforced with simple security measures, the main operations are summarized as follows: 1. Create a read-only account on nexus, for example, to view configuration and other information. Because nexus has a good and easy-to-operate RBAC control mechanism, this is a better implementation. A. Create a r

In the previous experiment, five. the combination of VPC and Fabricpath, called vpc+, can be regarded as fabricpath to two-layer network fusion and enhancement, then fabricpath how to combine with three layer network? The answer is: FHRP ( firsthop Routing Protocol), The First routing protocol is a generic term for several protocols, including HSRP VRRP GLBP,VRRP and HSRP are relatively common in comparison. In General, they work in a similar way, that is, several routers to act as a gateway to

description (3 ): Based on the existing POD, the new trill pod domain is expanded horizontally. the L3 gateway of the TRILL domain is located at the aggregation layer and connected to the core layer through the routing protocol; To solve the problem of dual-active access on the leaf layer, the leaf node supports N: 1 virtualization, such as the IRF of H3C; The two aggregation nodes also perform N: 1 virtualization to avoid VRRP configuration, so that the L3 forwarding traffic can be evenly shar

Itidentifies the one-time password on your list that you have to appendto the prefix password. If another login to your account is in progressat the same time, several password numbers may be shown and allcorresponding passwords have to be appended after the prefixpassword.
