Simple vlan issue

[pldcssIT]

I have 2 5406zl's that have been running a "flat" network with no vlans. I'm trying to introduce vlans by adding just one. I have a pc in that vlan (7) that can ping the firewall and the switch, but it can't ping any other ip in vlan 1. Nothing can in vlan 1 can ping the pc.

How do I allow traffic between vlans?

Also, is there anything special about DEFAULT_VLAN 1?

What does the clients in vlan 1 and 7 have as default gw? Probably this is a routing issue, the 5406zl routes between connected VLANs per default.

[pldcssIT]

vlan 1 has 10.1.121.1 as gateway. vlan 7 has 10.1.7.1.

[Fredrik Lönnman]

None of those IPs resides in the configuration you included.. could you please include the configuration from the device with that IP addresses.

Well, since you asked, but this is a Cisco ASA 5520. :-)

Hi

on PC's in VLAN1 Def.GW should be 10.1.121.151

on PC's in VLAN7 def.GW should be 10.1.7.2

this should do the job.

Regards

[Fredrik Lönnman]

Im not really sure if I understand how you have set this up.. do you have any static routes in the PCs or are they all following the default route? If they're following the default route the PCs in vlan1 will hit this route and be blackholed: "route Internal1 10.1.7.0 255.255.255.0 10.1.121.1 1"

I'm guessing it should look like "route Internal1 10.1.7.0 255.255.255.0 10.1.121.151 1", since the ASA doesnt seem to have an IP in vlan7?

[Fredrik Lönnman]

nvmnd.

You can do it by adding a static route or default route.

If you do it by adding a static route than the default gateway can be your Asa firewall.

If you do that by changing the default gateway you should add default route to your HP switches.

ip route 0.0.0.0 0.0.0.0 10.1.121.1

if the 10.1.121.1 is the Asa IP adress.

I have both a static and a default route at the end of the switch config. Should I put the static route: "ip route 10.1.7.0 255.255.255.0 10.1.121.1" in the vlan config? Wait, I think you're saying it should read like this: "ip route 10.1.7.0 255.255.255.0 10.1.7.2". Is that what you mean?

[Fredrik Lönnman]

No the route entry you have now "ip route 10.1.7.0 255.255.255.0 10.1.121.1" doesnt make any sense, since the 10.1.7.0 network is already directly connected via vlan 7. If the clients are using the ASA as default gateway without any other static routes on the _clients_, the ASA need to have a route to the 10.1.7.0 network via 10.1.121.151. (probably "route Internal1 10.1.7.0 255.255.255.0 10.1.121.151 1" would do it.)

Try to imagine the packet flow from the source to the destination and follow the routing table at each device in the path.

[pldcssIT]

I added "route Internal1 10.1.7.0 255.255.255.0 10.1.121.151 1" to ASA. Still no ping between vlans or internet access.

I've also tried 10.1.121.1, 10.1.7.1, 10.1.121.151 and 10.1.7.2 as gateways, but I still can't get out of the vlan.

Let me break this down into numbered items just so I can keep track of the variables. Also, let's focus on the switch first.

1.  Does routing need to be enabled on the switch?

2.  Does using a default route on the switch affect future vlans that won't need internet/other vlan access?

3.  Do I need to set up ACL's on the switch as I have done, or will traffic flow without them?

4.  If I set the default route on the switch to the ASA at 10.1.121.1, am I correct to think that I need no further route statements on the switch?

5.  If I set the default route on the switch to the ASA at 10.1.121.1, are you saying that the clients in the other vlans will use 10.1.121.1 as their gateway?

Thanks for all your help. I appreciate your time and efforts.

Hi,

first of all routing on the switch has to be enabled. There is no sense to put this kind of access list in the vlan because this access list does nothing except permitting all traffic which is by the default on these kind of switches.

You have to set the default gateway on PC's in VLAN1 the IP adress of that VLAN (10.1.121.151)

You have to set the default route on the switch 10.1.121.1

PC's in VLAN7 default gateway is 10.1.7.2. Port connected to CIsco is untagged in VLAN1 and all other ports are untagged in corespondece VLAN (except you want to propagate VLANS thorugh uplinks than you need to set that ports as untagged on both sides).

On cisco you need to add static route for 10.1.7.0/24 to point to 10.1.121.151. In this case it is  not needed to add other routes on switch except the default route.

It's working now. Thanks to all for your help.
