Does any 2500 Series router with any specific IOS support inter-VLAN routing (Router on a Stick?) I have a 2513 running 12.2(29a) which I am trying to create sub-interfaces for trunking and it will not recognize the "encapsulation isl vlan-id" command. Is it the fact that the router Ethernet port is only 10 Mbps or could it be the IOS? I'm pretty sure I have done this on a 10 Mbps port in a 3640 router with later IOS installed. Is it possible or am I mistaken?
I do have a 2520 router as well in case that makes a difference. Thank you.

Good thing these are borrowed then! Appreciate the information. I'll be working on my CCNP through next year and will need to build a small lab. Would it be worthwhile to have 2611 or 2621 (2 x FaEthernet) even if not an XM model, for things like having a Router on a Stick? I might have a line on a used one. I know 3640's are better, I have one now. Building a lab is not easy nor cheap!!!
You need at a minimum a 2610, which is configured with max memory and flash 64MB/16MB. Once you have that insure that it is running an IP Plus+ IOS later than 12.2T.
The following image would be current and support what you want to do;
However, make sure you have the appropriate license / support etc. You can find this using the feature navigator;
Major Release: 12.3
Feature Set: IP PLUS BASIC W/O HD ANALOG/AIM ATM/VOICE
Good luck with your search!
I would like to invite the person that is low-rating posts in this thread, that are 100% correct, to desist or explain the reason of such an inappropriate behavior.
Good morning, I'm new in Cisco forum; I need to ask about the ISL on cisco 2621: I would to buy a router 2610 (used) to build my lab to study for CCNA certification. I sow the answer of Inzeos781 in this forum posted Jul 4, 2007 where to configure the ISL is needed minumum 2610 with max memory and image c2600-is5-mz.12.3-22.bin and feature set IP Plus+ IOS later than 12.2T.
This is the version that I would to Buy: IOS (tm) C2600 Software (C2600-I-M), Version 12.3(22), RELEASE SOFTWARE (fc2), System image file is "flash:c2600-i-mz.123-22.bin", (not c2600-is5-mz.12.3-22.bin as Inzeos781 wrote)
1 Ethernet/IEEE 802.3 interface(s)
2 Serial(sync/async) network interface(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
Question: can I configure the Vlan ISL on this router in an ethernet 10 mbit and not fast ethernet, without maximum memory, only to study? If somebody or Inzeos781 could answer me I will grateful. Thank You in advance.
The 2520 in home labs is typically configured to act as a frame relay switch. It is an ideal piece of hardware because it is inexpensive and has four db60 style serial ports.
