• For longer engagements, contact me and I’ll help you engage our project with our professional services team (check out our experts).

ExpertExpress Case Studies

These case studies describe network design or deployment problems typically discussed during ExpertExpress sessions. They're based on real-life queries and consulting engagements but never represent an actual customer network.

BGP Convergence Optimization

Large multi-homed content provider has experienced numerous brownouts in the Internet edge of its data center network caused by high CPU load on the Internet edge routers following a link or EBGP session loss.

External Routing with Layer-2 Data Center Interconnect (DCI)

In a network with two data centers connected with a layer-2 DCI link, implement optimal route advertisement toward enterprise WAN and Internet that survives failures of individual links, node, or subsystems, and avoids split-brain scenario or traffic blackholing.

Redundant Data Center Internet Connectivity

In a network with two data centers (connected with a layer-3 DCI link), ensure the Internet users reach applications running in a data center even if all its Internet links fail.
