So i need the DMZ VLAN created on the firewall to go all the way down to the Layer 2 switches and into the vSwitches inside the hypervisor without communicating with other VLANs since this is DMZ network. Inside this VLAN you will also place the DMZ virtual machines. Thanks! Cisco is on a journey to making networking smarter with artificial intelligence and machine learning. This is what is supposed to do actually.and 2 another network is used at remote site. Instead of a default route going to a single internet connected ASA/Router, we’ll be using two ASA 5510s connected to two internet edge routers running BGP outside and iBGP between them. But my problem is all vlan is communicating with each other. Switch 2 and Switch3 are like layer 2 switch.Everything is working fine. Of course you can expand this scenario with more Vlans and more Layer 2 switches as needed.On the Layer3 Switch, for Vlan10 we will create an SVI with IP address 10.10.10.10 and for Vlan20 an SVI with IP address 10.20.20.20.
If I put another cisco l3 switch (c3550), would I use the same configuration of the l2 switch?For your first question: Normally for a Layer2 switch you use Vlan1 for management. However you must make sure that the ISP router has some sort of firewall or at least NAT capabilities so that to hide the internal network from the Internet.Glenn, thanks for your comments.
I can ping google from 1721 but not from switch. S7|E29 Increase Visibility and Enhance Security with Cisco AI Endpoint Analytics Lets say that this Layer3 link on your L3 switch is 192.168.5.2. On a Layer3-capable switch, the port interfaces work as Layer 2 access ports by default, but you can also configure them as “That is, you can assign an IP address directly on the routed port. Here is a topology in which we have a layer 3 switch connected to host devices namely PC1, PC2, PC3, PC4. Cisco Layer 3 Switch! Thanks and let me know if I can be more specific, thanks.DHCP is a Layer2 broadcast protocol and therefore can not pass through layer3 borders. 2.) The config files are below. Is it correct?
Remove vlan1 and put an IP address on the interface connected to inside of router (e.g make interface GigabitEthernet1/0/1 a “no switchport” port and then assign an IP address of 192.168.2.2).1- If i want to connect host remotely from out side network on vlan 10 , then what is suggested configuration?1- Do a remote access VPN or create a static NAT mapping of vlan10 host to an outside addresswhen i am trying to ping other pc in second vlan it is not working but i m able to ping default gateway of ather vlas..1) all vlans must be created on all switches as Layer2 vlanssir i am trying to create inter vlan communication for that ACLs must be there.Yes ofcourse you can do intervlan communication with a L3 switch. Refer to your diagram, let’s say I have an internet connection plugging to the layer 3 switch.
The IP address is in the same subnet as the default …
However, I’m running into a problem because of a slightly different setup.I’m using three 3750x switches.
Also, all interfaces connecting the three switches must be configured as The configuration above creates an Access Control List to restrict access between Vlan10 to Vlan20. In this scenario you have a Layer 3 FastEthernet port. Just to expand your topology a little, if I connect another L2 switch to either of the L2 switch port Fa/01, will all the ports of the new switch now belong to vlan 2 without me having to configure anything on the switchport?Yes, all hosts on the new switch will belong to VLAN 10 when their traffic goes from the new switch to the rest of the network. that server will be facing towards the cloud and will be entertaining all sort of requests.Here is a nice tutorial similar to what you need to achieve:We have a similar setup with the following vlans on 4500 switch connected to ASA: Each vlan represent a client therefore we need block them from each other. I also have another question, I sent this configuration to the team that manages our UTM/Firewall and they said they could not make the static routes ending with .0 to reach my vlans. Research this on Google for more information.im using the same topology that you have here in your blog. As I have said, traffic within the same vlan is not affected by the ACL, but traffic between vlans is controlled by the ACL.So 10.0.0.2 should be my interface ip address that will be my route set up to pass traffic? The ACL above is applied on vlan10 SVI in the “in” direction.The above ASA sample configuration shows the necessary static routing required on the ASA to route packets back to vlan10 (10.10.10.0) and vlan20 (10.20.20.0) via IP 10.0.0.1 which is the Layer3 switch IP.People ask me the question if you can route traffic between VLANs on Layer 2 switches. VLANs divide broadcast domains in a LAN environment. Its much more simple and cost effective to utilize one ASA for 2 ISP connections.Actually i am facing some problem while implementing ws-c3750g-12s Switch with 2960 series switches, and they allwhat i am facing is unable communication between two diffrent vlan’s is they any think to keep in mind even i enable eigrp on L3 switch and advertisement it show ip route, like all vlan’s are connected not D just C,and bu default 3750 should support routing, but it noti have a small doubt the ip is in class A range then why we are using 255.255.255.0 subnet rangeThis is called “subnetting”. It’s a subtle point, but not trivial with Cisco L3 switches.Using layer3 access lists to control traffic between vlans on a Layer3 switch is something that I have done several times in the past. Connecting Layer 3 Switch to Internet Router I am setting up multiple VLAN's in a small to medium size office with 180 hosts.
Thanks for any info you may have. The default gateway of Switch will be the router IP address of this subnet (and vica-versa).I implemented the topology using your article, 2 3750 Layer 3 Switches stacked together connecting to inside interface of ASA 5506-x , also configured Remote Access VPN and Site to Site VPN on ASA.Everything is working fine, except two issues, first one after connecting via VPN AnyConnect I am not able to ssh to inside interface of ASA, which is 10.0.0.2 & the layer3 ip address of the switch which is 10.0.0.1, but I am able to ssh to VLAN IP created on the switch.
