Trying to achieve ECHO request reaching destination in other VLAN

Question

I'm working in a network on packet tracer, when I'm sending ICMP requests from VLAN 20 (yellow field) to VLAN 10 (turqoise field) the packets get stuck at the switch where it is connected to.

Case 2: I'm trying to achieve the L2 and the L3 switch to function as a router with the goal to make inter-vlan routing possible.

Did I overlook something to correctly configure inter-vlan routing in this setup?

Networks used here:

• VLAN 10: 192.168.10.1/24 Server room
• VLAN 20: 192.168.20.1/24 Administration

Answer 1

It's almost impossible to tell without information such as VLAN and spanning tree status information on each switch, etc. but I would guess from a quick glance that you have problems between the switches due to the VLANs not being defined on the switch running version 12.2(37)SE1

You should set the hostname on the switches to make things clear.

You address the first switch as Layer 2 but it is clearly a layer 3 switch due to having SVI (VLAN interfaces) and DHCP functionality.

You also have the same network defined for DHCP function on both switches. Also the 3rd switch configuration is not shown at all so we can't really guess on what might be wrong there.

Start from the top down and check all of your configuration again to make sure:

VLANs are defined the same on all switches. VLAN interface IP addresses do not overlap. DHCP configuration is consistent.

Verify interface and trunk status on all switches. Verify spanning-tree status for each VLAN on all switches. Check log output when enabling interfaces between switches for errors relating to trunk configuration or VLAN errors and spanning-tree errors.

Answer 2

1. The VLANs need to be created on the L3 switch.
2. The gateway IP addresses must be configured on the L3 switch, on each VLAN interface/SVI.
3. IP addresses on an L2 switch are for management only - usually you only configure a single address in the management VLAN.
4. You should use friendly port names (kudos FrameHowitzer) for reference and to avoid misconfiguration.
