I am wondering what IP addresses to give to my management vlan on the switches in my network?
I have 3 LAN's but I think getting a result for one can probbably apply to the other 2.
There are 8 or so switches, some of the access layer switches have multiple vlans on them, trunked to another switch which is then trunked to another switch (there is some other switches about for redundancy but prob irelevant) which is then trunked to a router (with 3 sub interfaces for routing between vlans).
My management vlan is 99 and I was going to give "management" a subnet of its own in relation to IP addresses on interfaces vlan99 of the switches. I struggled when I realised it needs a default gateway.
Do I need to create another sub int on the router for vlan 99 or do I choose one of the LAN vlan's gateway??
