Hello,
Today we have some switches where we do BGP transit and L3/L2 to our Hypervisors and VM.
Our Hypervisors has local IP instead VM which are used for public and we have two vlans like public and private.
We are about to migrate our DC and separate L2 from L3 finally and we won't mix them so mutch.
Things is to avoid outage as much as we can.
We want to do stack switches where there are connected our Hypervisors and our fiber BGP, which in train to move at Mikrotik Router.
We use those Dell switches for aggregation our Hypervisors and they are connected Active/Active LACP to avoid downtime if one link comes down. Finally this is going to be in stack-switch.
Another Switch is used to connect second ISP who cares for our fiber clients but we don't care BGP, we only care for vlan interface configuration to pass their traffic inside our Network trunk to the Edge. We use only a gigabit port link from second ISP after we trunk to our internal network.
Now I am going the Core Switch to replace with another 2 dell switches in stack and connect my Hypervisors alone. I am confused a little about the second ISP if I am going to connect our fiber clients directly on Mikrotik router or not.
Once I achieve this, I am going to move IP routes to the Mikrotik and vlan as well.
What is the best way to avoid outage, I am very interested to hear from someone experiences in kinda complex things.
Thanks
