I'm confused by portions of the Cisco "VSS-Enabled Campus Best Practic Configuration Guide", specifically with the configuration example in Appendix A. The configuration example repeatedly shows seperate configurations labeled "Core 1" and "Core 2" where a virtual interface is given a different address on Core 2 than Core 1. How is this possible when they are in VSS mode? For example Port-channel1 is the "same" interface on both switches?
What basic concept am I missing here? I've attached an excerpt from the appendix. Look at the attached excerpt and look at the IP addresses assigned to interface lo0,lo1, and Po1
I am not sure if this config is for VSS or not, but I know for fact when 2 6500s form a VSS pair, they logically become one device and you cannot assign one loopback address to the primary and one to the stand-by. You can only assign one loopback address. As a matter of fact, once VSS is established you don't even have access to the stand-by to make config changes. Everything is done through the primary device.
