VLAN To VLAN
Is it possible to bridge one vlan to another vlan if they are on different subnets? Like can clients accessing to one vlan, access the resources on another vlan?
O my, Im sorry, i forgot that detail about the device, I am working with a CSS 11501. I have a vlan setup with two load balancing servers. The servers are plugged into the CSS, and theres a cable connecting to a 8 port switch on the same vlan. So if i plug my laptop into that 8 port switch I can access the load balanced servers. Lets say the subnet for this switch and servers is 10.0.0.X/24. Now i create another vlan with the same setup, 2 servers, 8 port switch, and cable from the CSS to the switch. But its a different switch on another subnet like 192.168.1.X/24. i want to be able to access the load balanced servers on the 10.0.0.X subnet from my laptop while plugged into the 8 port switch with the 192.168.1.X subnet. So I need to allow each vlan to access the other vlan right? So that is possible right? What contents of the manuals do I need to look at to get this accomplished?

VLAN to VLAN firewall rules support missing on RV180
How do I submit an RFE (Request For Enhancement) to the Cisco SBR team to encourage them to implement the missing support for VLAN to VLAN firewall rules that was available in the RVS4000 (See https://supportforums.cisco.com/message/3614106#3614106) and that was supposedly added to a beta release of the RV220W firmware (See https://supportforums.cisco.com/message/3614106#3614106)?
Hi Kelly, the RV220W does support LAN to LAN access rules on the 1.0.4.17 and it is released.
To make a feature request, it is pretty simple. Call the SBSC, have a case created for you. Tell the engineer you'd like to make a feature request. It usually gets escalated in 3 days or less.

Here is my network layout:
I have a cable modem connecting to a Linksys WRT54GL (DDWRT) router. Port 1 on the WRT54GL is connect to port 01 on the SG300-10 switch.
On the SG300-10 I've created two Vlans (Vlan 30 & Vlan 40). I assigned ports 3 & 4 on the SG300-10 to Vlan 30 and ports 5 & 6 to Vlan 40. Vlan 30 has the IP Address 10.10.30.1 and Vlan 40 has an Address of 10.10.40.1. The default Vlan (Vlan1) has an Address of 10.10.20.2. The default gateway (WRT54GL router) has an Address of 10.10.20.1. I have also enable DHCP relay on the switch and enter the command "ip routing". My question is on either vlan if I wanted to setup static addresses for clients would I use the 10.10.20.1 (WRT54GL) address as the default gateway? Also, what additional configurations do I need to make for the Vlans to be able to talk to each other and be able to access the internet?
Thanks,Van,
Thanks for the reply. The SG300-10 is in layer 3 mode. I have configured the DHCP server accordingly. Here is my setup:
cable modem
|
|
linksys wrt54gl (10.10.20.1)
|
|
sg300-10 Vlan1= 10.10.20.2 (manage)
Vlan30= 10.10.30.0 /24 (GW= 10.10.30.1)
Vlan40= 10.10.40.0 /24 (GW= 10.10.40.1)
You said that for inter-Vlan to work I need to set the clients GW to the switch. Would that be the Vlan's gateway for clients in each vlan? For example if a client was in vlan30 their gw would be 10.10.30.1?
The clients are not able to access the internet from the vlan. How would I configure the static on the switch for the vlans to be able to access the internet? Would this work: ip route 0.0.0.0 0.0.0.0 10.10.20.1? -
Create 2 VLAN (VLAN 1 & VLAN 2)
Hello all,
i need help and advice with my new Cisco SF300-48. I want to create 2 vlan (vlan 1 & vlan 2). The switch is set at layer 2.
example :
vlan 1 (port 1, 2, 3) , vlan 2 (port 4, 5, 6)
vlan 1 can communicate each other (port 1, 2, 3) and vlan 2 can communicate each other (port 4, 5, 6)
But vlan 1 cannot communicate with vlan 2.
Any help would be appreciated
Thanks,
JohanHi Johan, in a layer 2 environment VLANs are designed to not be able to communicate to each other. For intervlan communication, it requires a layer 3 device.
If you have the switch with 2 computers connecting on the different VLAN with no other devices connected, vlan 1 talks to vlan 1, vlan 2 talks to vlan 2. A router would have to be able to route between the VLANs. However, the router would have to support 802.1q and either trunk or sub interfaces to make it possible for the VLANs to communicate.

L2VPN Local Switching VLAN to VLAN issue on 7200VXR/NPE-G1
I've been working with a client trying to get this working. We tried 12.2(31)SB6, 12.4(15)T1 IP Services and 12.4(15)T1 Advanced IP Services.
It works fine for Ethernet to Ethernet, or Ethernet to VLAN, but it doesn't work for VLAN to VLAN either on the same interface or on different interfaces. We've tried this on both a Cat5505 as well as a Cat294XL thinking that maybe there would be some issues with one platform or the other.
Here's an example:

clear trunk 9/3 1-201,204-999
set trunk 9/3 on dot1q 202-203,1000-1005
We seem to be able to sequeeze a few packets through every once in awhile - like 1 or 2 every 20 or 30 packets:

Does L2VPN Local Switching VLAN to VLAN not work on VXRs or something?
This link seems to indicate that E-E VLAN is supported in 12.4(11)T.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s27/fslocal.htm#wp1149105
What am I missing?Hi,
In ASR9k, VLAN is port significant so yes you can match the same VLAN on different port.
For your untagged traffic, both UPE fo site 1 will think they are directly connected via two links so yes STP should take care about the loop
For your VPLS domain, if you are not using VLAN 100 on site 3, you need to pop the tag on both ASR9k. Also do you extend STP to site 3 ?
SVI is not supported in ASR9k today so you have to use unumbered interfaces instead:
interface Loopback1
ipv4 address a.b.c.d 255.255.255.255
interface g0/7/0/0.200
encapsulation dot1q 200
ipv4 point-to-point
ipv4 unnumbered Loopback1
proxy-arp
interface g0/7/0/1.200
encapsulation dot1q 200
ipv4 point-to-point
ipv4 unnumbered Loopback1
proxy-arp
I never tested it in this situation but from STP perspective those links should be seen as host connection.
Let me know if it works

Two SSIDs; different VLANs; second VLAN can't talk to Internet
I've got an ASA 5505 firewall with internal interface 192.168.65.1 on port 1 and a WAP connected to port 5 with the address 10.10.1.1. The WAP has two SSIDs configured; one is on VLAN 1 and the other on VLAN 14. The firewall has port 5 configured as a trunk for VLAN 1,14 and the interface was configured a VLAN 14.
If I connect to the WAP using the SSID on VLAN 1 I get an address of 192.168.x.x from our internal DHCP server and have full connectivity to the internal and external networks. If I connect to the SSID on VLAN 14 I get an address of 10.10.1.x from the firewall DHCP server but am unable to connect to anything.
When connecting to the SSID on VLAN 14 I want to be able to access the external interface but not anything internally. I have configured a firewall access rule to allow 10.10.1.0/24 to outside and deny 10.10.1.0/24 to 192.168.0.0/16 but this hasn't worked.
Any ideas?You need to configure an IP helper on the appropriate VLAN interface(s). Routers, by default, will not forward broadcast packets. Since DHCP client messages use the destination IP address of 255.255.255.255 (all Nets Broadcast), DHCP clients will not be able to send requests to a DHCP server on a different subnet unless the DHCP/BootP Relay Agent is configured on the router. The DHCP/BootP Relay Agent will forward DHCP requests on behalf of a DHCP client to the DHCP server. The DHCP/BootP Relay Agent will append its own IP address to the source IP address of the DHCP frames going to the DHCP server. This allows the DHCP server to respond via unicast to the DHCP/BootP Relay Agent. The DHCP/BootP Relay Agent will also populate the Gateway IP address field with the IP address of the interface on which the DHCP message is received from the client. The DHCP server uses the Gateway ip address field to determine the subnet from which the DHCPDISCOVER, DHCPREQUEST, or DHCPINFORM message originates.

RV042 VLAN to VLAN access?
I have 2 VLANs set up and I know they are set as default to not allow one to communicate to the other. Is there a way to set a rule to allow that? I'd like VLAN1 to be able to access VLAN2, but not the other way around.
The port-based VLAN feature of RV042 does not allow different VLANs to communicate with each other.
To support your scenario, you could try configuring multiple subnets under the Setup>Network page, and then configure Access Rules to restrict the traffic between the multiple subnets. -
1. when i use scvmm 2012 r2 sp1 ru2 to move a vm to another host(with no vlan trunk ) and change vlan 2 to vlan disabled. the network of vm was lost,when i check the network property on hyper-v management console ,i saw the vlan still the original setting,
but when i check the network propery on scvmm ,the vlan setting shows disabled,then i refresh the vm on scvmm console,the vlan setting shows vlan 2.
image 1, move a vm and change vlan settings to be disabled.
image 2. after vm was moved to another host ,the vm vlan settings shows on hyper-v console

I just created a VLAN (VLAN 5) on my 6509 switch. (I am running in Hybrid Mode)
I created a VLAN 5 interface on the Router of the 6509 and assigned it an address.
I assigned a port (3/43) on the 6509 to VLAN 5
I created an ip helper-address for VLAN 5 int. on the router, and I can successfully pull a dhcp address from the PC on port 3/43 in VLAN 5 from a DHCP server in VLAN 1. I can ping host on VLAN1 and accross my WAN environment,but I cannot get to the internet from this PC on VLAN 5.
I can successfully trace a route to google.com from the VLAN 1 interface of the router, but not the VLAN 5 interface, and I have the same results on the PC.
I checked my firewall to allow access from both VLANS, and logs show that it is not even getting hit from VLAN 5.
Any ideas on where I can look to allow VLAN 5 to route to my Internet connection would be great.Hi,
Can you answer the following questions.
1. Do you have an ACL/filter applied on the inside interface of the firewall?
2. Does the 6509 connect directly to the firewall. If so, what subnet (vlan) is the firewall inside interface on?
3. Does the firewall know how to route back to vlan5.
Pls. rate all helpful posts.

WPA321 VLAN / Management VLAN
Hey all,
i have a Network with multiple VLANs, VLAN 19-23 is for the WLAN (one per floor) because of security Reasons. All Switches got 192.168.1.xx IP Adresses. The VLANS have 192.168.19.xx to 192.168.23.xx So my WPA321 for example has the IP 192.168.19.2 (WIth VLAN 19 for WLAN Traffic) How can i set it up the way that the clients get the 192.168.19.xx IPs but the Router itself lies on the 192.168.1.xx network?
Thanks in advance!Are you talking about an autonomous AP right?
With regards to your case, you need to configure using the MBSSID setup,
ASSUME: VLAN20 MGMT VLAN
dot11 ssid VLAN119
vlan 19
authentication open -just a sample, configure as you desire
mbssid guest-mode
interface dot11radio 0
ssid VLAN19
mbssid
bridge-group 1 -already default, but just in case
interface dot11radio 0.19
encapsulation dot1q 19
bridge-group 2
interface gig0/0
encapsulation dot1q 19
bridge group 2
interface bvi 1
ip address 10.10.19.10 255.255.255.0 -ip mgmt of AP
AT SWITCH
interface f0/1
switchport mode trunk
switchport trunk native vlan 20
pretty much explainable your WLAN traffic gets tag with VLAN19 and since the native vlan is 20,
well you guessed it you can manage your AP -
RV220W - VLAN 2 VLAN single port access
Hi
I just bought Cisco RV220W router, and i have some problems connecting VLANs.
I have 2 vlans on my network. Now i would like to leave those 2 vlans seperate, so that nobody can go from one vlan to another.
But i want 3 exceptions.
1.) access from VLAN1 (default vlan) to a server (192.168.10.2) on VLAN10 port 3389 (RDP).
2.) access from VLAN10 to a server (10.10.10.3) on VLAN1 (default vlan) port 62000.
3.) allow ping from VLAN10 to a server (10.10.10.3) on VLAN1 (default vlan).
Thanks for all your help in advance.

NAtive VLAN?what is the use of vlan?VLAN in trunk link?
what is the use of native VLAN in trunk links? where should i change native vlan from vlan1 to another?
what is the use of untagged native VLAN frame?Hi,
On ethernet, you can connect more than one device to a port. So when you configure a port as trunk, it expects a vlan tag to arrive. But some times there are devices which dont have the capability to tag the packet and still they need to connect to network. So they can use native vlan to have connectivity. It is not a usual situation, but it helps on some situation where multiple devices connected on a trunk and not all have ability to send tagged frames. Hope this helps.
Please do remember to rate all useful posts.
