Does the 2600 router support intervlan routing?

Nikk92

Hi,

can anyone tell me if the 2600 router supports inter vlan routing? I am trying to configure it to do so but the router only has 10mb ethernet port although it will let me create sub interfaces on it. Will I have to reduce the speed on the swithports to 10mb too?

According to the Cisco documentation you need a fastethernet port but I have not tried it on a ethernet port. Others here say that it is supported on an ethernet port but I can not verify that. Check out this link http://www.cisco.com/warp/public/473/50.shtml for more info.

Funnily enough I just finished reading that linkbefore you posted it. If you follow the comand syntax for the router, the 2600 that they use on that example is fast ethernet.

So I guess the bottom line question is:
is it possible to do intervlan routing through a 10mb Ethernet port?

You need trunking and subinterfaces to do this. The 2500 series does not support this thanks to the 10M ethernet chipset. I believe you need FastEthernet to make this work. If anyone can make it work on a 10M 2500 series interface I would like to know.

Hi,

I am not talking about the 2500 series, I was taliking about the 2600 specifically 2612 IOS version 12.3.

Although my router has only 10mb e port.I can create sub interfaces.

At the moment I can ping each host on seperate vlans via the router but cannot ping each hosts on different vlans from host to host. But I can ping host to host that are on the same vlan. So I guess the problem must be with the router.
I feel like I am almost complete with this lab...So near yet so far

Yes

Can you ping the hosts from the router? Do you have the host gateways set to the router's IP Address on the sub-interface for the vlan? Can the hosts ping the router sub-interface for the vlan? etc...

Thanks Mike,

so its my configuration So can you pop round here and show me where I went wrong? I`m just outside Bangkok

It might just be easier if you play with it for a bit and then if you don't get it, post your config. Someone should be along shortly and can critique your config -- it's just after 3am here outside Chicago and I should try to get at least 3 hours of sleep. Plus I'm on-site tomorrow, er... today, and then it's the weekend....

Make sure you manually configure trunking on the switch (and make sure the encapsulation type matches between router & switch).

Do a show ip route on the router and make sure you see the connected networks on the sub-interfaces.

Nikk92

many thanks for your advice. I`ll keep at it

I made a stupid gateway error on the host, I miss typed it, You where correct. It works fine now. My very first intervlan network strange I was looking too deep into a simple solution.

That's right. I know you were talking about the 2600. I threw in the 2500 experience as you say you are also using 10M ports. But it looks like you have a solution! The 2500/2600 controllers are most probably different. If I remember 2600 was the spec you needed to do this. It's been a while since I had to do one armed routing.

Glad it's working for you!

Here's a config for anyone else interested.
