I have a HP ProCurve 5412 as my core switch. I have about 10 VLANs working fine on it, with the 5412 doing the routing between the VLANs.
I have a 3COM 3870 switch on the edge. I have an Exchange server plugged into this switch on VLAN 100.
My issue is that users on VLAN 1, 20, 30 etc that are on this 3870 switch must go through the 5412 to talk with the Exchange server. The default gateway for each VLAN resides on the 5412. I really want to keep the traffic local in this 3870 switch without having to go to the core and back.
How would I set this up? I would assume I would need to enable Layer3 routing on the 3870?
I just need some pointers so I can get this working in a test lab.
PokerMunkee need a bit more detail; do all users on all vlans require access to the 3870? Conversely do users on the 3870 vlans require access to the core, I assume the core is where the servers are housed, authentication etc? Do you have a tolopolgy drawing you can up?
