Appendix AVSS-Enabled Campus Best Practice Configuration ExampleEnd-to-End Device ConfigurationsThe end-to-end devices configuration is categorized into three major sections. Each sectionconfiguration contains specific CLI which is a required as part of best practice configuration andcorresponding explanation. VSS and L2 Domain- Includes above base configuration as well as L2 domain configuration Access-layer- Sample L2 domain configuration L3 Domain - Includes global L3 configuration for VSS and core routers. Then separate section forspecifics topologies (ECMP and MEC) for EIGRP and OSPF. In addition, the core devicesconfiguration shown below are standalone router/devices.VSS SpecificVSS Global Configurationswitch virtual domain 10 !
