Thatâs an all-too-familiar scenario today. With this practical book, youâll learn the principles behind zero trust architecture, along with details necessary to implement it. All traffic in and out of the data center not only passes through the aggregation layer but also relies on the services, path selection, and redundant architecture built in to the aggregation layer design. This is my study plan for the Cisco CCNP Datacenter. •10 GigE/10 Gigabit EtherChannel uplink support—It is important to determine what the oversubscription ratio is per application. Layer 3 access has the following characteristics: •All uplinks are active and use CEF load balancing up to the ECMP maximum (currently 8), •Layer 2 adjacency for servers is limited to a single pair of access switches in the Layer 3 topology, •VLAN extension across the data center is not possible. The DFC permits local routing decisions to occur on each line card via a local Forwarding Information Base (FIB). The aggregation layer provides a primary and secondary router "default gateway" address for all servers across the entire access layer using HSRP, VRRP, or GLBP default gateway redundancy protocols. However, this is not usually a viable solution because of the additional service modules that are required.

The data center core is interconnected with both the campus core and aggregation layer in a redundant fashion with Layer 3 10 GigE links. ". They deliver high performance and density for both data center and campus cores. Although the Cisco Catalyst 6513 might appear to be a good fit for the aggregation layer because of the high number of slots, note that it supports a mixture of single and dual channel slots. The multi-tier model is the most common model used in the enterprise today. From a campus core perspective, there are at least two equal cost routes to the server subnets, which permits the core to load balance flows to each aggregation switch in a particular module. This trend is expected to increase and could create a density challenge in existing or new aggregation layer designs.
