Hi
I know how to route between vlan.
and i did this by using fast ethernet port

example :

configure terminal
interface FastEthernet0/0.20
 encapsulation dot1Q 20
 ip address 192.168.20.1 255.255.255.0

but the router i got, which is only Ethernet port , it does not have fast Ethernet..

and i believed you can use encapsulation dot1Q , with fast Ethernet only

but is there any way i can do this by Ethernet port only ??

thanks for your help

You have the config correct, so if you apply the config to a non-802.3u, say a 802.3i (10Mbps Ethernet)
and it fails and the device is not on that list, or not in the feature navigator for supported devices, then no.


Take care

Well, in your case, it is just the software that will not allow the configuration; you will just need to upgrade your IOS to  12.2(2)T or any later releases. You can find the images with your favorite search engine

Ok i need more help

can you give me the full image name of the ios(12.2(2)T )  so that i can download it from net

also , will my router allow that ios or not ??

Commented:
if u want to have routing between VLAN then you can use SVI see this video it clarify it

and if u want to upgrade to say 12.3 then 96/32 will be ok see the below link

The lowest one I see is c2600-is-mz.122-8.T.bin (IP Plus)
It requires 64MB of DRAM and 16MB of Flash.

Yes, the image I just posted will work on your router (Per Cisco Feature Navigator; I have yet to come across a search and download and a feature was not supported even though the site stated so). It appears that you do not have enough Ram in the router to run the image, so you need need to upgrade the DRAM and Flash.

CEF  Support for IP Routing between IEEE 802.1Q vLANs

in that case... i will either update or will buy one 2611 Xm router ...

-you saying about this one , is not it ?
Correct, you need at least IP Plus from what I can see:

The feature you need is:

IEEE 802.1Q VLAN Support

http://tools.cisco.com/ITDIT/CFN/Dispatch?act=featdesc&task=display&featureId=346

http://www.cisco.com/en/US/docs/ios/lanswitch/configuration/guide/lsw_cfg_vlan_encap.html

Either upgrade your RAM, Find an image that is  12.2(2)T -  12.2(7)T that is IP Plus that will fit with the RAM Config you have, or buy a new router.

Good Luck

I used GNS3/Dynamips to pass my CCNP

Never used physical hardware; tho it does help, but to save you a few thousand dollars, go with the emulation software. It is free!

@rfc1180

u said you used gns3 for CCNP but i think it lacks on switching part isnt?i added an NM-16ESW module in it for switching but it doesnt even support normal switching command like creating an VLAN it only gives this

Router(config)#vlan ?
  accounting  VLAN accounting configuration
  ifdescr     VLAN subinterface ifDescr

we can use vlan  database command but  then if we want to see sh vlan bri it doesnt work


how did you solve this problem for simulating switching lab in gns3 i need urs advise


Thanks++
