smallest IOS based router with 3 ethernet interfaces

Hi!

What is the smallest IOS based router which has 3 Ethernet Interfaces?

Thanks,
Christian

 

I don't know about the smallest, but if I understand correctly, the
837 has a four-port switch, one port of which can be changed into
a full LAN interface.

 

What is the smallest IOS based router which has 3 Ethernet Interfaces?

1. interface types - routed or just switched or a mix ?

2. if just switched - 1 VLAN or multiple VLANs ?

831 with a particular IOS can have up to 3 interfaces.

1 WAN e4 (? - i don't know how it is called)
1 Ethernet (normally linked to the 4 switch ports) e0
1 Ethernet (linked, when put in no shutdown mode, to FastEthernet 4)

I used an 837 as a ethernet router substaining rates up to 2 Mbits/sec (due to bandwidth limitation on a router behind
the 837)

Hi!
Thanks fpr all input so far.
I need routed interfaces.
I think I will go with a used 1720 with 2 WIC-1ENET.

Ah, you're in Germany; if I understand correctly, the law there
requires that the software be transferable. Most places in the world,
you would encounter the problem that the software license does not
[normally] transfer when an IOS router is sold; by the time you
pay the fee to "relicense" IOS from Cisco, an 83x would likely be
less expensive.

Even in your location where [if I understand correctly] you are
entitled to continue to use the license that is already on the
machine, if you find that you need to upgrade to a newer IOS version,
the cost to do so could be high, depending on the features you need.
It probably is not -so- bad for a 1700 series, but by the time of
the 3600 series it can be a big expense.
