I am new to VLans, and have been thrown into a situation. Situation is: Site has 8600 (96 ports)and 8 remote Baystack 450's. This was started but not completed and within a few weeks we neefd to move our network over to this backbone (Right now it is on many many smaller switches. Anyway, whoever started this has a 255.255.255.192 subnet mask on all equipment. User has about 90 PC's, 12 Printers, 30 Server like devices and ancillary equipment, and of course 9 management IP addresses. There are 4 VLANs setup.
Scope-------------------Gateway---
X.X.62.1 X.X.62.61 X.X.62.62
X.X.62.65 X.X.62.125 X.X.62.126
X.X.62.129 X.X.62.189 X.X.62.190
X.X.62.193 X.X.62.253 X.X.62.254

Users in VLAN 2 and 3 need to be able to see Servers in VLAN 1. If I plug into a port that is in VLAN2 and set an IP in that range I can talk to other devices in that VLAN, but I cannot talk to say VLAN 1 or 3. I can also configure the port to be in VLAN 2 AND 1 and can only talk to VLAN 1 if I change my ip address to be in that range. So what is the easiest way to allow VLAN 2 or 3 to see devices in VLAN 1.

I know, annoyingly easy question but I have READ ALOT including other posts on this forum and still can't grasp the theory. I am not asking for a handout of step 1....Step 2... but if someone can explain the theory, I show Routes in the 8600 that show Destination X.X.62.0 Subnet 255.255.255.192 Next Hop X.X.62.62 and so on for all 4 VLANS but it just doesn't seem to work. This is all with testing from JUST the 8600. Once I get that going I'm sur ethe 450's will be a peice of cake.
 
Try to add static route at 8600.

Example:
Dest X.X.62.64 Subnet 255.255.255.192 Next Hop X.X.62.126
Dest X.X.62.128 Subnet 255.255.255.192 Next Hop X.X.62.190
Dest X.X.62.192 Subnet 255.255.255.192 Next Hop X.X.62.254

450 is layer 2 device, do not need to cater.
 
ola viper222:
the 8600 will not do any routing if you don't give the vlans IP addresses..
of course, requirement for each PC to be able to talk across vlans is: have a default gateway pointing to the 8600's vlans' IP addresses correspondingly.
you DO NOT NEED ANY STATIC ROUTES if you do it this way; after all, 8600 is a routing switch.

one example might be (if the switch configured correctly):

config vlan 1 ip X.X.62.62 255.255.255.192
config vlan 2 ip X.X.62.126 255.255.255.192

and to make sure, if you do 'sho ip route' those IP addresses should show up as LOC (meaning they're locally connected).
so, as long as the PCs have their default gateway correctly setup to the 8600, they should be able to talk to each other.
