This document uses a catalyst 3550 as an example.
Procurve layer 3 switch routing.
The answer is no.
Inter vlan routing on layer 2 switches.
If there is no routing device in the network layer 3 switch or router then hosts connected to two different vlans on the same layer 2 switch will not be able to communicate.
People ask me the question if you can route traffic between vlans on layer 2 switches.
We have hp procurve 2650 s at the two remote sites and an hp procurve 5304xl at the main location.
I want to set up 3 different vlans on each layer 2 switch.
A layer 3 switch is a specialized hardware device used in network routing.
However the concepts can also be applied to other layer 3 switches that run cisco ios for example catalyst 3560 3750 catalyst 4500 4000 series with sup ii or later.
Both can support the same routing protocols inspect incoming packets and make dynamic routing decisions based on the source and destination addresses inside.
Routing is not currently enabled and the switch only functions at layer2 at the moment.
The second layer 2 switch will have vlan 500 600 and 700.
The current configuration is very basic with only 1 vlan assign to all switch ports.
To prevent at t from seeing all the macs on each side of the opt e man we need to set the switches to route all the vlans on layer 3.
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.
On catalyst switches it is accomplished by the creation of layer 3 interfaces switch virtual interfaces svis.
Layer 3 switches technically have a lot in common with typical routers and not just in physical appearance.
The default gateway for all the vlans.
Current configuration with hp procurve 2848 switch at a colocation facility consists of using the isp switchport as the default gateway.
Layer 3 static routes.
If the firewall is configured with a vlan interface for this.
The first layer 2 switch will have vlan 200 300 and 400.
Ok lets login to the hp v1910 24g using the ip address and username password we assigned previously.
