Since the inception of Cisco NX-OS on Cisco Nexus data center switches, the Virtual Port Channel (vPC) feature has received numerous enhancements that improve the reliability of vPC-connected devices during failure scenarios and optimize forwarding behavior of both vPC peer switches. ...

VRF:Virtual Routing Forwarding,虚拟路由转发实例。在一台交换机上启用VRF,可以虚拟多台交换机,三层之间相互隔离。每个VRF独立管理自己的路由表。 一般VRF在L3VPN中使用,在PE设备上,为每个直接相连的Site建立并维护专门的VRF实例,即VPN实例。每个实例有自己的IP路由表、标签转发表、与VPN实例绑定的接口以及VPN实例的管...

Figure 4-11illustrates the traffic forwarding in a vPC environment. In the left diagram, the data traffic reaching Cisco Nexus switches Agg1 and Agg2 from the core is forwarded toward the access switches acc1, acc2, and acc3 without traversing the peer Cisco Nexus switch device using the vP...
(or more) of the available system bandwidth is off limits to data traffic, and the other problem is that a failure of the active link tends to cause multiple seconds of systemwide data loss while the network re-evaluates the new “best” solution for network forwarding in the Layer 2 ...
