Cisco Routing between VLANS

I have a cisco 837 and a 2610. Can I use any of these to program subinterfaces to route between these VLANS ?

If not, what is the minimum spec router I would require ?

Trying to do a router on a stick config for lab practice.

 
The only requirement for a 2610 to route between vlans is full duplex ability. That I believe is with IP Plus IOS code (is-mz). As far as the 837 goes, I doubt the switchports have many config options, and I am not sure they would trunk. I would tend to say no, but a decent switch (like a 2924XL) would be very cheap (usually under $50) on Ebay.

thanks for the response guys.

Im trying to configure the sub-if for the different vlans on the 2610 but i get the following error. Any reason why this is ? I do have full duplex capability.

Using ios version :

IOS (tm) C2600 Software (C2600-I-M), Version 12.2(6), RELEASE SOFTWARE (fc2)

Is this version good enough ?


Router(config)#interface ethernet 0/0.1
Router(config-subif)#ip address 192.168.1.10 255.255.255.0

Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q, or ISL vLAN.

 
you have to first setup encapsulation method...

interface FastEthernet0/1.1
description $FW_INSIDE$
!the 2 below is for vlan 2
encapsulation dot1Q 2
ip address 10.100.100.5 255.255.255.252
ip nat inside
ip nat enable
ip virtual-reassembly
!
interface FastEthernet0/1.2
description $FW_INSIDE$
!the 1 below is for vlan 1
encapsulation dot1Q 1 native
ip address 10.100.100.9 255.255.255.248
ip nat inside
ip nat enable
ip virtual-reassembly
!
interface FastEthernet0/1.3
description $FW_DMZ$
!the 3 below is for vlan 3
encapsulation dot1Q 3
ip address 10.100.100.1 255.255.255.252
ip nat inside
ip nat enable


We must go always forward, not backward
always up, not down and always twirling twirling towards infinity.
 
the word encapsulation isnt recognised under that interface.
 
It appears your IOS won't support it. You are going to need the IP PLUS feature set, at least, to support VLAN tagging.

For example:

Image Name c2600-is-mz.122-6.bin
DRAM / Min Flash 48 / 16

Or you could upgrade to enterprise plus:

Image Name c2600-js-mz.122-6.bin
DRAM / Min Flash 48 / 16
 
Reiterating what I said...is-mz

the "s" meaning "plus", the "i" meaning "IP".
