This is not my network. I'm trying to understand why my cloud provider insists that they need to take down both routers when performing updates.
From what I understand they have 2 Cisco 6500s clustered via VSS, active-active. When they perform an upgrade, they always take both down at the same time. My question is, why? Isn't the whole idea of this setup is so that you don't have to take them both down? Take one off-line, update/upgrade it, bring it back on-line, take the other off-line, update/upgrade it, bring it back on-line.
Where am I going off the rails with this? I pay for redundancy but don't seem to be getting it.
