Procurve Layer 3 Switch Routing

The current configuration is very basic with only 1 vlan assign to all switch ports.

Procurve layer 3 switch routing.

When designing a network with a layer 3 switch at the distribution layer it is very important to understand which device is set as the gateway for clients on each subnet if the l3 switch is the gateway for clients downstream subnets any upstream firewall must be configured with a static route to that downstream subnet. The answer is no. I have a hp 1920 layer 3 switch and i have two hp procurve 2530 switches. Routing is not currently enabled and the switch only functions at layer2 at the moment.

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. Ok lets login to the hp v1910 24g using the ip address and username password we assigned previously. Both can support the same routing protocols inspect incoming packets and make dynamic routing decisions based on the source and destination addresses inside. Layer 3 switches technically have a lot in common with typical routers and not just in physical appearance.

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. This document uses a catalyst 3550 as an example.

Then all at t sees are the macs of the three connected switch ports. On catalyst switches it is accomplished by the creation of layer 3 interfaces switch virtual interfaces svis. We have hp procurve 2650 s at the two remote sites and an hp procurve 5304xl at the main location. The default gateway for all the vlans.

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. Inter vlan routing on layer 2 switches. 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 first layer 2 switch will have vlan 200 300 and 400.

People ask me the question if you can route traffic between vlans on layer 2 switches. I want to set up 3 different vlans on each layer 2 switch.
