Hi
In order to do Inter-Vlan routing with a 2620, do I need IP Plus IOS?
If the IOS does indeed need to be IP Plus, I will have to add more DRAM to
the 2620. Currently the router has a 32M module of DRAM. Can I just add
another module into the second slot - is it that easy? Any gotchas I
Hi,
yes, your router need IP Plus to running ISL or dot1q for Inter-vlan
routing.
You should check out the flash and memory size for IP Plus, that is easy to
install it.

You don't need the IP+ feature-set to route VLAN's. I just tried creating a

I think the most reasonable and versatile choice would be a 2600. Keep in
mind that you need an IOS and Feature set release that supports both. I
