Hi Rene,
Let’s say we have a request to add a private vlan on an access switch. Access switch connects to core, core is connected to a firewall. In some cases, the SVI between the core and firewall are already configured as a normal vlan. If we add a primary vlan config under this interface (SVI) will it change it to a primary and a regular vlan? Is this possible? Or will it become a “primary” vlan for the secondary private vlan and loose its prior connfig? Whats the best method to implement a private vlan to an already existing access switch, that is connected in the same fashion I mentioned earlier without breaking anything? Assuming the SVI connected to the fireall is default gateway for hosts to the internet? I hope I correctly explained myself.
Thanks
