Traditional inter-VLAN routing using physical interfaces does have a limitation. As the number of VLANs increases on the network, the physical approach of having one-router-interface-per-VLAN quickly becomes hindered by the physical hardware limitations of a router.Lewis, Wayne (2008-04-28).

A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.
A trunk connection is affected by broadcast storms on any particular VLAN that is carried by that trunk.
inter_vlan routing on d'link DGS3612 is automatic,you just creates vlan and tag them to the port access and trunk
switch(config)#int type <no> switch(config-if)#switchport mode trunk switch(config-if)#switchport trunk allowed vlan all/vlan no switch(config-if)#exit switch(config)#exit switch#
The IP address of each router subinterface mist be used as the default gateway for hosts on the corresponding VLAN.
1) reset the revision number before installing. 2) have a backup switch with existing VLAN data.
Using a simple show command will suffice to view that vlan's are configured properly. If the vlan's are configured properly on the routers as well as the switches, then the routers can talk to each other and so can the vlan's.show ip route - Provides a snapshot of the routing table entries.ping - verifies connectivity
Configuring Standard STP Parameters STP is disabled by default on Routing Switches. By default, each port-based VLAN on an HP device runs a separate spanning tree (a separate instance of STP). An HP device has one port-based VLAN (VLAN 1) by default that contains all the device's ports.
