Overview - Review
Basic SLB architecture. Current layer 2 SLB features, current layer 3 SLB features. Layer 7 switching Cookie/URL switching/hashing and cookie insertion. The purpose of health check and types of health checks. SYN-Guard and SYN-Defense.
Server Load Balancing
L2 vs.L3 SLB option. Barrel Processors - Dynamic Distribution. Configure basic SLB as review/start point for more complex labs. Configure primary and backup servers. Configure SLB using VLANs with Virtual Routing Interfaces. Configure OSPF for use in SLB with VRRP/E. Setup multiple sub-nets and multiple virtual routing interfaces. Configure SLB using NAT. Configure Stateless TCP/UDP ports. The SLB session table, SLB session table parameters, policy-based SLB.
Health Check
How a basic health-check works, differences between active and passive health checks, Boolean health checks, developing scripted health checks, implementing scripted heath checks.
Layer 7 Switching
The difference in persistence using URL/Cookie switching and/or hashing. Using cookies for session persistence, Cookie insertion, inserting a Cookie into an HTTP header, using cookie switching and hashing.
Global Server Load Balancing
The GSLB metrics and their function, configuring GSLB with metrics set to different values, the advantages and disadvantages of the different GSLB options (including IP-Weight and Site-Weight), Route Health Injection for GSLB.
Transparent Cache Switching
Key TCS design techniques, Active-Active TCS with a remote cache server, configuration for proxy caching, configuring TCS and SLB using the same ServerIron.
ServerIron Security
Security. SYN-Guard/SYN-Defense configuration. Benefits of rate limiting, URL Filtering, Transaction Rate Limiting, Connection Rate Limiting.
Troubleshooting
