Cisco switches+Router and Win2k server
 |
Hey,
I have 2912 catalyst with simple setting total 3 vlan (192.168.1.x, 2.x, and 3.x) - the default ip is 192.168.1.10.
port 1,2,3,4 Vlan 1,
Port 5,6,7,8- Vlan 2
port 9,10,11,12 - vlan3
I have win2k server with 3 scopes 192.168.1.x, 2.x, and 3.x. At this moment connect to port 1 (I dont know if I have to set it to trunk port - ISL or 1q?).
I have 1720 router with 2 eth, one is 100mb the other one is 10mb
I would like to get PC that connects to port 5-8 will get an IP from W2k-Server (192.168.2.x)
and PC that connects to port 9-12 will get an ip 192.168.3.x
I am very newbie to CCNA - I able to set VLAN on switch.
Can some please share with me on how to set router and switch in order to get 3 vlans working.
Thanks for your help.

Unfortunetly the 1720 does not support inter-VLAN routing, the 1721 and up does. Also you MUST run IP Plus IOS code or better.
Here is a sample switchport config off switch:
!
interface FastEthernet0/1
description TRUNK TO INTER-VLAN ROUTER
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
duplex full
speed 100
!
*** dont forget to add the vlans to the vlan database!!!!
Here is the router interface that it is plugged into:
!
interface FastEthernet0/0
no ip address
speed 100
full-duplex
!
interface FastEthernet0/0.1
description VLAN1
encapsulation dot1Q 1 native
ip address 192.168.1.1 255.255.255.0
!
interface FastEthernet0/0.2
description VLAN2
encapsulation dot1Q 2
ip address 192.168.2.1 255.255.255.0
!
interface FastEthernet0/0.3
description VLAN1
encapsulation dot1Q 3
ip address 192.168.3.1 255.255.255.0
After port 1 on the switch is configured, and the router interface is set you can put put the remaining switchports into their "access" vlan (including the server which only needs to be in one vlan if you use the IP helper command on the subinterfaces on the router.)
This can be confusing stuff to get a grasp on, if you need clarification please feel free to drop another post on this thread.

THANK you very much for your generous and kindness Help. I will try it tonite. I should by 1721 instead of 1720 
. I will look at Ebay to see any good deal on 1721.

FYI all 2600's support dot1q routing, even the plain old 2610 as long as you are running at least 12.2 IP Plus. These may be cheaper than a newer 1721.
Thank you for the Post. I just checked ebay, yea, 2620 is about less than $200 used. I am looking for router with two 100MB ports - are there exist? or would be way more expensive?
Other note: As previous note, my Win2k server-3 DHPC Scopes will be plug in port 1 (Vlan1). How about the router? which port on swtich I should connect to?
The 1720 that I have, there are two NIC ports, 1 is module plug-in, I believe it's 10MBps and it's for WAN/DSL something, the other port is 100MBps for LAN.
Thanks again.

The smallest Cisco router with two 10/100 ports built in that I am aware of is the 2621.
I usually use the first port on the first switch to plug in my router and configure it as a trunk. I also use a special color cable in production networks to warn admins that it is special, then label it, my best practice.
I would plug your server into port 2 and make it vlan 1 only. Configure your three scopes on the server (did you know you could run a dhcp server on the router itself? check out www.routergod.com for a tutorial) On the subinterface of vlan 2 and 3 on the router put an ip-helper pointing to the ip of the server, dhcp should be served! Ip-helper has a tutorial on routergod too if you want to know all the ports being forwarded.
BTW there should be a model number on that card "WIC-????" which card to you have in your 1720?

You can connect the server with aany switch port, configured with Vlan 1.
For router which will support your requirement is:
1. 2611 XM
2. 2621
3. 2621 XM
4. 2651
5. 2651 XM
etc.

Hi w1r3sp33d,
It was a while that I was no able to resume.
I did setup as you suggested. the VLANs can communicate between Vlans; however, they can not get IP address from the DHCP server. Only ports on Vlan1 are able to get. ports on Vlan2 and Vlan3 are not able to. In Win2kSrv DHCP server, I did create 3 scopes, 192.168.1.x for VLAN1, 192.168.2.x for VLAN2, and 192.168.3.x for VLAN 3. (only 1 interface is connected to port on VLAN1 - Not Trunking port)
Are there any additional settings I have to proceed?
When there is an IP discover packet how the Win2kSrv would know which VLAN it come from and which scope it would release IP?
Thanks,

I think you need Trinity's help: http://www.routergod.com/trinity/
Probably much more info than you need, but it will address other issues with splitting a M$ environment across subnets without adding remote servers.

Trinity was so good !
Please shred the light further:
"Well, put you ip helper-address command on the interface that receives the broadcasts, then in global config mode enter the command: ip forward-protocol udp 2000 and that should do the trick."
My DCHP Srv IP address 192.168.1.1 with 3 scopes (1.x, 2.x and 3.x), the Switches IP is 192.168.1.2, and the router IP is 192.168.1.3.
Should I enter command ip helper-address in every ports (interface) and which IP shall be input after 'ip helper-address'? I assume 192.168.1.1 across all the ports of all Vlans?
Mille Thanks.
