Here is what I have so far. I am trying to set up a Vlan network consisting of 4 subnets.

ROUTER INFORMATION:
Int F0/1
No switchport
IP add
Int F0/2
No switchport
IP add
Int F0/3
No switchport
IP add
IP access-group initial in
Int F0/4
No switchport
IP add
Router EIGRP 6035
Network
Network
Network
No auto-summary
IP access-list extended initial
10 deny ip
20 deny ip
30 deny ip
40 permit ip any any log

My instructor says it still needs work. Can anyone steer me in the right direction.

A short, practical checklist that ties together the thread so far.

is trying to give each VLAN its own L3 gateway. Two common, correct ways to do that are: use a layer‑3 switch with SVIs (one SVI per VLAN) or use a router with either one trunked physical link and 802.1Q subinterfaces (router‑on‑a‑stick) or multiple routed physical interfaces (each connected to an access port on the switch). is correct that 802.1Q encapsulation is required when using subinterfaces. ’s suggestion to review TCP/IP/subnet fundamentals is useful because wrong masks or wildcard masks will break routing and ACL matching.

Quick checklist and troubleshooting steps:

  • Confirm switchport mode: trunk to the router for subinterfaces, access to the correct VLAN for routed ports or SVIs.
  • For router‑on‑a‑stick use encapsulation dot1Q <vlan-id> on subinterfaces and ensure the switch port is trunking.
  • Verify ACL placement and order: ACLs are processed top‑to‑bottom; an inbound ACL on an interface that matches the local subnet will block that traffic immediately.
  • Collect diagnostic outputs: show ip interface brief, show interfaces trunk, show access-lists, show ip route, show ip eigrp neighbors to see address assignment, trunking, ACL hits, routing and adjacency.
  • If using a routing protocol, ensure the routing configuration actually advertises each subnet (wildcard masks matter).

A concise reference on the router‑on‑a‑stick pattern is available from Cisco: .

hi, you must know how a network (lan) works...before you try to do somethings which is complicated...try to explore more and learn more.. check out google for TCP-IP fundamentals..it might lead you how to configure your VLAN...good luck..

1.Wich router do you have?
2. you dont have encapsulation on this router
