you have multiple switches, PCs, and a server, with what looks like a trunking and VLAN setup.

Topology Role

Likely Switch0 (center top) is your core/distribution switch, possibly Layer 3 capable (multilayer switch) handling VLAN interfaces.

The other switches (Switch1, Switch2) appear to be access switches for end devices.

HSRP Issue

In your earlier config, VLAN30 had an HSRP virtual IP in the wrong subnet. That will cause the mismatch warning.

Correct VLAN30’s standby IP to match the 192.168.30.x network.

Trunking

Make sure all inter-switch links (the dotted lines in your diagram) are configured as trunks:

switchport mode trunk

switchport trunk allowed vlan 20,30,40

Verify native VLAN if you use one:

switchport trunk native vlan 1

VLAN Database

Create VLANs on all switches (if not using VTP):

vlan 20

vlan 30

vlan 40

EIGRP

Ensure all VLAN interfaces with IPs are advertised in EIGRP:

router eigrp 100

 network 192.168.20.0

 network 192.168.30.0

 network 192.168.40.0

If you have other networks (like 192.168.10.0 for servers), include those too.
