Hey Jim
Supposing you take a new switch out of the box and don't configure any
vlan's etc, all the ports will still be using a vlan. That vlan is called
vlan1 and all ports are on vlan1 by default. The devices on those ports
wouldn't need any router to route traffic since they all belong to the

Hi,
If I have two Vlans and want to route between them using an external router,
but the router has only 10mb ports, how can it be done? I can't use ISL or
802.1q because it isn't supported on 10mb/s ports, correct? Does every Vlan
need a separate physical connection? or do i use sub interfaces?
ISL is not supported on 10mbs interfaces. You need the ISL header so that
you retain the VLAN information. If you had a 100mbs interface is would look
something like this. This would set up int fa0/0 as a trunk and it would be
trunking VLAN 1,2,3.
int fa0/0.1
encapsulation isl 1
Ip address
Well, here's the deal. What's the reason for the VLANs? Since each of
the PCs in each VLAN are on a different IP subnet, it's possible to just
combine all of the PCs into a single VLAN, then setup the router interface
with two IP addresses (one for each IP subnet). If your reason for the

Here's the deal... I have a 5500 with RSM with a few VLANs on it,
each VLAN with an IP and the RSM is handling the routing for all VLANs.
I've got one VLAN in particular (511) that I'm experimenting with I
made the following access list:
Router#(config)access-list 10 deny any log
If 10.51.1.1 is the only IP active on that subnet, then the traffic is
not being sourced from that network, thus rendering the ACL irrelevant.
If, however, your host was connected to one of the ports on vlan 511,
you would not be able to communicate with the RSM past the ACL.
So, in other
Jay,
Thanks for your input. But shouldn't ACL keep anything from other VLANs
from even pinging the gateway IP of VLAN511?

No, that's not the case. If you think of it visually,
INTERNET-ROUTER-INTERFACE-ACL-LAN
Then you will see that the internet can still access the interface, and
it's address. Because really, you are pinging the router, not the
interface or the LAN.

Greetings all,
Just for clarification purposes, are there any advantages/disadvantages
or a specific purpose to change the mtu size for a vlan(Ethernet Vlans)?
I looked everywhere on Cisco's page, no luck.

Nabil, in my opinion it would not be to any advantage. Seems like more
