PPT-Understanding Layer 3 Redundancy

Objectives Upon completing this lesson you will be able to meet these objectives Describe routing issues in connection to redundancy Explain the router redundancy process and . Understanding High Availability. Components of High Availability. The objective of high availability is to prevent outages and minimize downtime.. Achieving high availability integrates multiple components:. Diana Cole. University of Kent. A model is parameter redundant (or non-identifiable) if you cannot estimate all the parameters.. Caused by the model itself (intrinsic parameter redundancy).. Caused . Aditya Akella. UW-Madison. Growing traffic vs. network performance. Network traffic volumes growing rapidly. Annual growth: overall (45%), enterprise (50%), data center (125%), mobile (125%)*. Growing strain on installed capacity everywhere. Rosalie Cattermole, Senior Associate. Claire Tuffield, Solicitor .

Layer 2 Distributed VLANs on Access Switches. Not a recommended design — slow convergence. Use only if Layer 2 VLAN spanning flexibility is required. Requires STP convergence for uplink failure and recovery. Alexander Afanasyev. Jiangzhe. Wang. Chunyi. . Peng. LIXIA ZHANG. AINTEC 2011. November 11, 2011. Presented by . Lixia. Zhang.
