Note No license is required for BFD features. BFD has the following configuration limitations: NX-OS supports BFD version 1. BFD supports single-hop BFD; BFD for BGP supports single-hop EBGP and iBGP peers. BFD depends on Layer 3 adjacency information to discover topology changes, including Layer 2 topology changes. A BFD session on a VLAN interface […]

Standard platform licensing The core Salesforce Platform consists of several products, as follows: These products are all built around the core application framework and relational database that underpins the Salesforce Platform. In fact, Sales Cloud, Service Cloud, and Experience Cloud can all be thought of as enhancements to the core Lightning Platform. For example, Sales […]

Foundation Topics An Overview of LANs The term Ethernet refers to a family of LAN standards that together define the physical and data-link layers of the world’s most popular wired LAN technology. The standards, defined by the Institute of Electrical and Electronics Engineers (IEEE), define the cabling, the connectors on the ends of the cables, the […]

Replication options When you create a storage account, you can also specify how your data will be replicated for redundancy and resistance to failure. There are four options, as described in Table 2-2. TABLE 2-2 Storage account replication options Replication Type Description Locally redundant storage (LRS) Makes three synchronous copies of your data within a […]

Reserved As the name implies, with this model, customers can choose to essentially reserve a fixed capacity for their workloads, based on either a one-year or a three-year commitment. Reserving capacity is an ideal scenario when you have a steady workload that will essentially run 24×7, 365 days without much interruption. AWS offered (and still […]

Bidirectional Forwarding Detection Bidirectional Forwarding Detection (BFD) is a detection protocol designed to provide fast forwarding–path failure detection times for media types, encapsulations, topologies, and routing protocols. BFD provides subsecond failure detection between two adjacent devices and can be less CPU-intensive than protocol hello messages because some of the BFD load can be distributed onto […]
