Hello,
Currently, our network has a collapsed core type design.
But we only have one network core (a stack of 4 x 3850 switches).
Routing, svi, ACL... are on the core network
9 stacks of 2960 access switches are connected to this core network.
3 of these stacks are reserved to connect our esx servers, storage array. the other 6 are used to connect PCs, IP phones, etc...
So we don't have distribution layer switch.
and put a double attachment of each access switch to core 1 and core 2, and connect these 2 cores by a redundancy protocol 'in active / standby mode?).
we want to replace core 1 with a stack of 9300 and 9300 too for core 2.
what protocol used, hsrp, vrrp?
If we set up a redundancy protocol between 2 stacks, how does it work?
Do the stack and the hsrp / vrrp not contradict each other?
If I make a modification on core 1, does the hrp/vrrp apply this modification on core 2?
Thanks.
