What is inter-VLAN routing on a layer 3 switch?
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfaces (SVIs) ).
Is a VLAN Layer 3?
VLANs address issues such as scalability, security, and network management. VLANs can also help create multiple layer 3 networks on a single physical infrastructure. VLANs are data link layer (OSI layer 2) constructs, analogous to Internet Protocol (IP) subnets, which are network layer (OSI layer 3) constructs.
How do I create a VLAN on my HP router?
- Configuration on Router A. Create VLAN 100, and assign port GigabitEthernet 4/1/1 to VLAN 100. system-view. [RouterA] vlan 100.
- Configure Router B as you configure Router A.
- Configure Host A and Host C to be on the same IP subnet. For example, 192.168. 100.0/24.
How to solve VLAN routing on hp 5412zl?
Where 172.16.3.0 was the network needed to connect and 192.168.0.27 is the IP of the routing HP Switch. Also IPCop does not remember these beyond reboots so it has to be added to the rc.d scripts that run on startup. IPCop has some documentation on how to do this on their site for the different version. 02-21-2013 07:40 PM 02-21-2013 07:40 PM
How to set up VLANs on L3 managed switch ( hp 1910 )?
Creating the VLAN interface is what tells our HP 1910 switch to enable L3 routing. To create our VLAN interface, go to Network > VLAN Interface > Create: Creating a VLAN Interface on the Switch. This tells the switch to route VLAN traffic and by assigning the switch an IP address, we are also defining the gateway for that VLAN.
Why does hp v1910 use layer 3 static routes?
The reason for this is the HP v1910 can also do layer 3 static routing so in my home environment the switch is the default gateway as well. OK, lets login to the HP v1910 24G using the IP address and username/password we assigned previously. Why use layer 3 static routes? Well I want to be able to route between VLAN’s.
What does a L3 switch do for a router?
An L3 switch takes the routing functionality of a router and offloads it to the switch itself, allowing the switch to route traffic between VLANs. So an L3 switch gives you the security through the principle of compartmentalization (via VLANs), while also allowing you to route traffic between those VLANs on the switch itself.
