Hi Everyone
Last time I posted a question everyone was really helpful. I'm trying to get better at networking and this forum is great, so thanks a bunch
My question is :
When you want switches to be accessible for management externally, you create a management VLAN on them and give that VLAN an IP address. With router on a stick, this vlan will be made accessible from the outside by giving it a default gateway that corresponds to the router subinterface created for it.
But what about when you use a L3 switch for intervlan communication? You will have to give this management vlan an IP as you would normally, but this would act as the default gateway for the other switches that need to be managed externally through the management vlan. Will the L3 switch's management VLAN interface have an IP for default gateway functions for all the other devices on this vlan, as well as another IP on the same vlan for its own default gateway needs?
If I'm not making sense my question in essence : Vlans need a default gateway to communicate with each other. When the default gateway is external on a router thats straight forward, but an L3 switch will already have an ip address for management vlan to act as default gateway for everyone else on the vlan, but what about its own need for a gateway to communicate with the outside?
Thanks!
