The IP address is in the same subnet as the default router. If you are not able to ping the interface, verify that the host’s default gateway points to the corresponding VLAN interface IP address and that the subnet masks match.
If the ping test is successful in step 3, but fails to reach the downlaod device on the other VLAN, l3 switch configuration pdf download that the default gateway on the connected device is configured correctly.
The information in this document was created from the devices in a specific lab environment. If your network is live, make sure that you understand the potential impact of l3 switch configuration pdf download command. This is known as inter-VLAN routing. In this example, ping from VLAN l3 switch configuration pdf download The bandwidth number can be used in order to manipulate routing metrics, calculate interface load statistics, and so forth. In this example, you want to route traffic between VLANs 2, 3 and Also verify the interface VLAN status by issuing the show ip interface brief command.
Before you attempt this configuration on a series switch, ensure that you meet these prerequisites: See this table in order to determine whether your switch can support interVLAN routing. If they do not exist, add them on the switch. Refer to the appropriate client configuration guide for more information on how to designate the default gateway.
Downlosd of the devices used in this document started with a cleared default configuration. The no switchport command makes the interface Layer 3 capable. Related Support Community Discussions. In this example, you can use a host on VLAN 2 Therefore, the ip default-gateway command is unnecessary.
In this section, you are presented with the information to configure the features described in this document. Also verify that the IP address and subnet mask on the switch are configured correctly.
Configure InterVLAN Routing on Layer 3 Switches
If the switch receives a packet for a network not in the routing table, it forwards it to the default gateway for further processing. The ip default-gateway command is used to pdt l3 switch configuration pdf download default gateway when routing is not enabled. The scenario can be expanded to include a multi-switch environment if you first configure and test inter-switch connectivity across the network before you configure the routing capability.
If you are not able configuratioj ping between two devices on the same VLAN but not on the same switch, verify that trunking is configured properly and that the native VLAN matches on both sides of the trunk. Note that the routing table has an entry for each VLAN interface subnet.
Before you attempt this configuration on a series switch, ensure that you meet these prerequisites:. This logical diagram explains a simple interVLAN routing scenario. Here is troubleshooting information relevant to this configuration.
Check the show running-configuration. See the Prerequisites section for more information. This document provides the configuration and troubleshooting steps applicable to the creation of Layer 3 interfaces. Enable routing on the switch with the ip routing command.
Configure InterVLAN Routing on Layer 3 Switches – Cisco
On Catalyst switches it is accomplished by the creation of Layer 3 interfaces switch virtual interfaces SVIs. Configure your end devices to use the respective Catalyst VLAN interface as their default gateway. Introduction This document provides the configuration and troubleshooting steps applicable to the creation of Layer 3 l3 switch configuration pdf download. The command, if enabled, appears towards the top of the output. This document assumes that Layer 2 has been configured and that l3 switch configuration pdf download devices within the same VLAN connected to the communicate with one another.
From the switch, verify that you can ping the default router.
Follow the instructions in order to troubleshoot your configuration. If the ping fails, verify that IP routing is enabled and that the VLAN interfaces status is up with the show ip interface brief command.
Was this Document Helpful? This step can be omitted if the switch reaches the default router through a VLAN. If you are not able to reach the Internet or corporate network, verify that the default route on the points to the correct IP address l3 switch configuration pdf download the default router.
Home Skip to content Skip to footer. Make note of the VLANs that you want to route between. However, in this case, routing is enabled from step 1. From the diagram in the Task section, note that the IP address of the default router is The default is BW Kbit 1 Gigabitbecause the route processor internal inband is only 1 Gigabit by design.
Configure the l3 switch configuration pdf download to the default router. The default route with the next hop If you are not able to ping between two devices on the same VLAN on the same switch, verify that your source and destination ports have devices connected to them and are assigned to the same VLAN. This document uses a Catalyst as an example. Verify whether ip routing is enabled. The bandwidth parameter on the show interface l3 switch configuration pdf download output is not fixed bandwidth used by SVI as traffic is routed on the switch backplane.
Contributed by Cisco Engineers. Even if IP routing was previously enabled, this step ensures that it is activated.
