Cisco Firewall :: ASA 5520 Inter Vlan Routing At Low Speed

Nov 24, 2011

I have ASA 5520 and SSM-10 module. During copy between vlans, connected to gigabit port of asa the speed is up to 6,5 Mbyte/sec. Network cards and trunked switch are gigabit. I've temporarily disabled SSM but it didn't work. Here is my config. Also I found out, that putting SSM into bypass mode solves the problem. But I don't send any traffic to IPS. [code]

Cisco VPN :: ASA 5520 Firewall - Inter VLAN Routing

Jul 31, 2011

We use Cisco Any connect with a Cisco ASA 5520 firewall.  Today I changed the inside interface of the firewall's IP because i needed to do some inter vlan routing and needed to move the inside interface from the lan vlan to a routed port on our 3750. 

Now people can vpn and authenticate to the MS radius inside but cannot access any network resources nor ping anything inside.

Cisco Firewall :: Inter VLAN Routing With ASA 5520 And Cat 2960?

Jul 26, 2010

I am a complete novice at networking, but I was tasked to have an ASA 5520 do inter VLAN routing (since my shop doesn't have a layer 3 router).As a basic setup, I am trying to have three workstations on three different VLANs communicate with each other.  The attached screenshot shows the topology. I am unable to ping from a PC to the ASA...therefore I can't ping to other VLANs.

Cisco Switching/Routing :: ASA 5520 / Preventing Inter VLAN Routing?

Mar 28, 2013

I am working for a large campus network. The network has more than 70 VLANS in a Layer 3 Switch(Catalyst 4503). Customer wants to stop intervlan routing between all vlans except 2 vlans. How will i do that? I have also a Firewall (ASA 5520) & a Router (2811) in up of the switch. Besides this, I have run HSRP in Layer 3 Switches for redundancy.how will i stop intervlan routing between VLANS except 2, with ACL or any other process has?

Cisco Firewall :: Inter VLAN-Routing ASA 5505?

Jul 8, 2012

Ive been readin all over the internet (including this site) trying to figure out if the asa can handle intervlan routing. Im not sure what I am missing on my config to get this to work.  Ive read that it can work and Ive read that it cant work. How to get this to work on my asa 5505.
 
Here is my setup
 
Cable Modem ---> ASA (eth0/0) 
(eth0/2) -->unmanaged switch for LAN connectivity
(eth0/3) --> Access point for wireless LAN connectivty
 
My config is attached
 
What I would like to do is be able to communicate between vlan3(LAN) and vlan4(Wireless LAN)
 
Whats strange is I can RDP between the two vlans but I cant ping or anything else.

Cisco Firewall :: ASA5525x - Restrict Inter-vlan Traffic

Jan 11, 2013

I have a customer, who has the SVI's configured on the Core (4500x) and this is connected to a ASA 5525x,  there is a requirement of restricting traffic between different vlans. How can i use the ASA to accomplish this task. ACLs on the Switch are not stateful and hence not considering this option, Also we are not planning to configure the GW's on the ASA since there is lot of traffic between the vlan's and this will become a bottleneck

Cisco :: STP And Inter-vlan Routing?

Apr 12, 2012

Just messing around with packet tracer for a little practice. I tried to setup a router on a stick config with 3 switches trunked and PCs on different vlans. Anybody know of any issues that may arise with STP and inter-vlan routing? I set everything up correctly with trunking, addressing, encapsulations, vlans, but did not touch STP. Unable to ping from any PC to any where.

Inter-Vlan Routing SG500

May 12, 2013

I know very little about switches. This is the first time I've ever touched them. However, I'm the only one in the company who has the slightest knowledge on how to make them work.

4 vlans
vlan 1 - 192.168.32.1 - Existing network with Internet access
vlan 33 - 192.168.33.1
vlan 34 - 192.168.34.1
vlan 35 - 192.168.35.1

From the laptop on vlan 33 I can ping the management interfaces (192.168.x.1) for each of the vlans. However, I cannot ping anything on those networks.

Below is what I have with the config. Right now not much attached to these switches until they are setup.

Code:

Cisco :: Inter-VLAN Communication Without Routing?

Feb 25, 2013

Say I have a managed switch that supports VLANs. I have two computers and one server connected to the switch (I'll call them PC-1, PC-2, and SRV-1).Without routing, I want both PC-1 and PC-2 to talk to SRV-1 and vice versa, however I don't want PC-1 or PC-2 to talk to each other.I achieve this by making each port a trunk port. I make PC-1 a member of VLAN 2, PC-2 a member of VLAN 3, and SRV-1 a member of VLAN 4. The port that SRV-1 is on I make a tagged member of PC-1 and PC-2 (VLAN 2 and 3 respectively) and make the ports the PCs are on a member of the SRV-1 VLAN (VLAN 4).Everything tests OK (that is, the clients can't talk to each other, however the clients can individually talk to the server)

Cisco Switching/Routing :: Inter VLAN Routing On N5548P Without L3 Daughter Cards

Jun 1, 2013

I have a DC topology based on 2 layers, access and aggregation, based on 2 pairs of N5548Ps, both without L3 Daugher Cards. My intent is to use the aggregation N5K pair as L3 inter VLAN layer, so I configured all the VLAN default GWs there. The 2 layers are interconnected via vPC, in a double-sided vPC topology for some N2Ks and some vSwitches. The point is that, despite connecitivity is working fairly ok, for some applications, like file transfer via either FTP or HTTP, between hosts in different VLANs, the performance is too poor. The file transfer starts ok, but after a while it becomes lower and lower. ICMP is working, but I can see some strange random behaviour, like having some packets taking more that 20 ms (sometimes 40 or more), whilst average is 2 ms.

I read through some articles saying that until you don´t have the L3 license (the one coming with L3 Daughter Cards) you can expect some weird behaviour on L3 level. Is that true?. What can I do apart of purchasing L3 Daughter Cards?. Can I enable L3 Basic license at the moment (I don´t need dynamic routing for now).
 
Here some excerpts of what I´m saying:
 
PING results:
10000 packets transmitted, 10000 packets received, 0.00% packet loss
round-trip min/avg/max = 0.809/2.496/57.559 ms
 System version: 5.0(3)N2(1)

Cisco Switching/Routing :: Inter-VLan Routing On Catalyst 3750 Switch

Dec 17, 2011

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
 
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
 
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to  (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet.  I think it has to do with the routes.

Cisco Switching/Routing :: 5505 Inter-vlan Routing With Multiple Gateways

Feb 15, 2013

We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .

Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]

Cisco Switching/Routing :: Inter-VLAN Routing Using 877 And SG300-10 Switch

Feb 5, 2012

I recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
 
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
 
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
 
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
 
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.

Cisco Switching/Routing :: 6500 / Restricting Inter-VLAN Routing?

May 9, 2013

I'm looking to restrict Inter-VLAN routing through L3 switch (cisco 6500) and wanted to know best possible way to do it. I used VACL and achieved success to some extent, but my config is making clients take up to 5-6 mins to authenticate IP address from the DNS (bootps).My VACL config was as follows:
 
Subnet to restrict is 10.100.15.0 (VLAN 15)
 STEP 1: Created extended ACL to allow bootpc/bootps through DNS
ip access-list extended EACL_DNS
permit udp any eq bootps any
permit udp any eq bootpc any
 
STEP 2: Created standard ACLs to allow only relevant subnet, server VLANs & some IPs from other subnets for printers/scanners etc.

ip access-list standard SACL_VLAN_15
permit 10.100.15.0 0.0.0.255 (the subnet I'm restricting)
permit 10.100.50.0 0.0.0.255 (server VLANs)
permit 10.100.25.45 0.0.0.0 (printer in another VLAN which has to have access in VLAN 15)
 
STEP 3: Created VLAN access list

vlan access-map VACL_15 10
match ip address EACL_DNS
action forward
 vlan access-map VACL_15 20
match ip address SACL_15
action forward
 
STEP 4: Applying VLAN Access list on VLAN 15 vlan filter VACL_15 vlan-list 15 Though the above works, below is noted:

1. I'm still able to PING 10.100.15.2 (the switch virtual interface) from outside the subnet, which I don't intend to do so. Howeve all cients in the subnet have no connectivity from outside the VLAN 15.
 
2. As mentioned its taking quiet some time to negotiate with the DNS server at system boot time.

Cisco Switching/Routing :: Nexus 7010 - Inter-VLAN Routing On Multilayer VPC Environment

Feb 16, 2011

you find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.

Cisco WAN :: 2811 / Inter VLAN Routing Non-Operational?

Jan 11, 2013

I have set up a 2811 with seperate VLANs for phones, and another for computers/printers. Fa0/0 is trunked to a 3560 switch, which has all end devices plugged in. I have enabled the IP Routing commands on both devices, and from advice turned off proxy-arp on the VLANs on the router (unsure if this is causing the issue). The setup is as follows
 
Computer VLAN = 192.168.20.0
Phone VLAN = 192.168.50.0

Both on the same subnet, along with a router loopback address in the same subnet, at 192.168.10.1.I am having an issue understanding why, but if I try to ping a phone from a PC it times out. Or if I try to type the phone's IP into an internet browser to get the phone's GUI on screen, it fails. This should not be happening as IP routing has been enabled on both, and everything is in the same subnet, correct? PC's can ping other PC's and network printing works fine. Phones register and operate fine, but the two VLAN's will not interoute.Furthermore if I try and ping the router's loopback from the switch, it fails. But the trunk is up and operational because DHCP and devices work within their own VLAN. If I try to ping end devices from the switch, it returns 100%. There seems to be an issue with the router looping the different networks together.

Cisco Switches :: SGE2010 Inter VLAN Routing

I have created 2 VLANs using 192.168.10.x and 192.168.20.x (using .50 for the VLAN IP address in each case) - however, I need to be able to allow certain traffic between the VLANs.Alternatively, to get things started - I'm assuming I need to set up ACLs to allow access between VLANs - how would I configure the switch to allow all traffic from one VLAN to the other?

Cisco 3560 VLANs And Inter-VLAN Routing

Sep 29, 2011

I have no router inplace that can do trunking (5505 basic license )I have 2 VLANS 10 Data 20 voice I have given both VALNs IPs lets say

-VLAN10 192.168.1.1
-VLAN20 192.168.2.1

Enabled IP routing and set the router as the gateway of last resort.Now becuase the L3 switchis doing the routing I have had to set the default gateway as the VLAN IPs. So PCs on VLAN10 get a gateway of 192.168.1.1 and phones on VLAN20 get a gateway of 192.168.2.1

Any real downside to having the 3560 doing the VLAN routing, is this the "correct "way to do things in the event I don't have a trunkable router?

Cisco Switches :: SG300-28P - Inter VLan Routing?

Mar 17, 2012

configure my new SG300-28P. When I have started the switch, I have specified a new password and enabled telnet in order to setup the switch in Layer 3 mode.
 
After a restart, the switch took its IP address from a DHCP server. When I try to set a static IP address (192.168.2.1), I receive the following error message: Duplicated IP interface on the same subnet.
 
The IP address 192.168.2.1 is not used by any device within the network. For information, the message doesn't appear when the switch is in Layer 2 mode.
 
why I can't change the IP address of default vlan in Layer 3 mode ? All I can do is set the IP address to static or dynamic.
 
For test purpose, I have added 2 vlans. But I wasn't able to route traffic between vlan. how to configure the switch to route traffic between vlan?
  
find below details informations about my VLANs.

- Default (VLAN ID 1)
IP Address : 192.168.2.1

Cisco Switching/Routing :: 2821 Inter-Vlan Routing And IP NAT To ISP?

Jun 25, 2012

I have just bought myself a Cisco 2821 ISR.At present in my home I have a Cisco 2621XM. Fast Ethernet 0/0 is connected to a 3524XL as a trunk to provide my LAN with inter-vlan routing. it works great. Fast Ethernet 0/1 is connected to my ISP's cable modem and uses the command "Ip address dhcp" to get an IP and all other info from my ISP.FA 0/1 is Ip nat outside and the FA 0/0 and all sub interface like 0/0.1 .24 .168 etc all ip nat inside.I get intervlan routing and access to the internet via this router.I have this 2821 to replace the 2621XM as I plan to run CME on it and want gigabit routing on my vlans as at the moment on the 2621 routing between vlans it at half duplex or seems to be.I have configured the 2821 to ip nat outside on  gig 0/0 and ip nat inside on gig 0/1 and all of the sub interfaces (same setup as my 2621 but with gig ethernet)I have no access to the internet at all but I can ping www.google.co.uk and other domain names from the terminal session when I am connected to the 2821 via the console or telnet/SSH. the gig 0/0 has an IP assigned from my ISP too but no other nodes on the network can ping outside.Am I missing something here? the version of IOS is V 15.
 
My access list goes someting like
 
access-list 1 permit 10.0.0.0 0.255.255.255
access-list 1 permit 192.168.1.0 0.0.0.255
access-list 100 permit ip 10.0.0.0 0.255.255.255 any
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
 and so on

Cisco Switching/Routing :: Inter-Vlan Routing With 2851

Nov 27, 2012

I have one cisco 3750G-48 switch, one cisco 3560G-PS switch, Cisco UC520, cisco 2851 and cisco wireless access point.i have setup up intervlan routing between the two cisco switches and the uc520 with a total of four VLANS, the problem i'm having is with the 2851 router, I have created a trunk between the 3750 switch and the 2851 router. should I create subinterfaces on the 2851 router for the four vlans by doing gigabieethernet 0/0.1, 0/0.100 and so on or should I create BVI subinterfaces.
 
reason I ask is I created four vlans on the vtp server switch which is the 3750 and I connected the uc520 to the 3750 switch via a trunk interface and set up vtp client on the uc520, after I setup p the vtp on the uc520 the vlans were automatically created on the uc520 with each vlan having its own BVI interface.
 
So I am not sure how to configure the 2851 router to interact with the four vlans. also the 2851 router have two hwic 1adsl wics installed which will have two adsl connections coming in.how to set up the 2851.
