    I’m going to try to explain this as best as possible..

    I’m working in packet tracer.

    I have a Router on a Stick set up on the left side as follows:
    PC1 10.10.10.1 255.255.255.0 Gateway:10.10.10.10
    PC2 20.20.20.1 255.255.255.0 Gateway:20.20.20.20
    Both connected to Sw1 via access links allowing vlan’s 10 and 20 respectively.
    The link between Sw1 and Router 1 is a trunk link with encap dot1q, currently allowing vlan’s 10,20,30,40.

    Router1:
    Fa0/0.10
    Trunk encap dot1q
    Ip add 10.10.10.10 255.255.255.0

    Fa0/0.20
    Trunk encap dot1q
    ip add 20.20.20.20 255.255.255.0

    Fa0/1
    ip add 150.101.45.2 255.255.255.248

    On the right side, I have a second Router on a stick setup as follows:
    PC3 30.30.30.1 255.255.255.0 Gateway:30.30.30.30
    PC4 40.40.40.1 255.255.255.0 Gateway:40.40.40.40

    Again, both connected to Sw4 via access links allowing vlan’s 30 and 40 respectively.
    The link between Sw4 and Router 2 is a trunk link with dot1q, currently allowing vlan’s 10,20,30,40

    Router2:
    fa0/0.30
    Trunk encap dot1q
    ip add 30.30.30.30 255.255.255.0

    fa0/0.40
    Trunk encap dot1q
    ip add 40.40.40.40 255.255.255.0

    Fa0/1
    ip add 150.101.45.4 255.255.255.248

    IN between Router1 and Router 2, I have Switch2 and Switch3. All links (Router1—switch2—-switch3—-router2) are configured as trunk links allowing vlan’s 10,20,30,40.

    I have static routes set up on both routers to the 10,20,30 and 40 networks.

    So here is my issue: Before i added switches 2 and 3, I could ping between all four hosts. After adding the switches I cannot get through them, but I can ping the 150 side of each router from their respective hosts.

    Note: I have not configured Vlan 150. I tried to do so as access links and I got Native Vlan mismatches, so i replaced it with trunk links allowing all four vlan’s.

    Any advice is appreciated.

    Thanks,
    Kevin.
