inter-vlan routing question

what is the best way to restrict inter-vlan routing once it has been enabled on a L3 switch? for example, what is the recommended way to allow user traffic to route to the user and server vlans, but keep it from routing to the management vlan and vice versa. should i just use access lists, or is there an easier way?

thanks,

Matt

Matt,

On a L3 switch when you configure different VLANs and their respective SVI's, all communication between the VLANS are permitted by default

You have to use access-lists to permit/deny specific traffic on the SVI's.

HTH, rate if it does
