now the router won't work to the L3! before this turns into a "Trevor your a moron" thread, does anyone see what is wrong with this config; I'm just not seeing it. I swear if I'm missing a period or one line of code like back in COBOL days I'm going to be this smiley, physically and literally.... crash.gif


Here is a picture of the topology:

    The 3550 is sending tagged frames and the router is dropping them.

    so basically what you saying is ...one line...

    so I'm taking a educated guess:

    interface FastEthernet0/24
    switchport trunk encapsulation dot1q
    switchport trunk allowed vlan 80 - IS NOT NEEDED?
    switchport mode trunk


    if this is so... on the verge of crash.gif ....

    Are you trying ROAS? I don't see a trunk configuration or sub interfaces on the router.

    Is that what you are talking about?

    You've configured a trunk port with 1 allowed VLAN, vlan 80. When something in vlan 80 on the switch sends a frame out that port the 802.1q tag is added. The router interface is unaware of vlan 80, it just expects normal Ethernet frames to arrive. In other words, what the switch sends and the router expects to receive are different. Communication router to switch will also fail but reason will be the opposite. You could fix it on the router side or on the switch side.

    PS.
    Basically, you need to either stop tagging the frames on the switch or make the router interface aware of vlan 80 and accept those frames.

    PPS.

    I follow completely. I do see that I forgot to reference the vlan 80 on the router side. Just because I like learning, going to remove the tagging on the switch to get it working. And then do RoAS with using multiple vlans per connection, sub-interfaces basically. I've done it twice before just need ot find my notes and cater it to this topology.

    I just sometimes need a second set of eyes looking at things; I'm not perfect I miss things.

    Thanks for the clarification!

    At the dealership right now doing a transmission flush on my car and in normal fashion i can't just wait till I get home.

    going to do this:

    Cisco 2600:

    interface FastEthernet0/0 |
    description To_Cisco-3550(LAN 1-2) |
    ip address 172.16.7.9 255.255.255.0 | - I'm pretty sure I do need this configured, but I don't have | my notes so I could be wrong
    speed auto |
    full-duplex |
    !
    c2600#configure terminal Enter configuration commands, one per line. End with CNTL/Z. !

    c2600(config)#int fastEthernet 0/0.80
    c2600(config-subif)#encapsulation dot1Q 1 native - not sure if this is needed. icon_lol.gif
    c2600(config-subif)#encapsulation dot1Q 80
     c2600(config-subif)#ip address 172.16.7.12 255.255.255.0
    c2600(config-subif)#exit
    c2600(config)#int fastEthernet 0/0.100
    c2600(config-subif)#encapsulation dot1Q 100
    c2600(config-subif)#ip address 192.168.102.12 255.255.255.0
    c2600(config-subif)#exit
    c2600(config)#int fastEthernet 0/0.200
    c2600(config-subif)#encapsulation dot1Q 200
    c2600(config-subif)#ip address 192.168.104.12 255.255.255.0
    c2600(config-subif)#exit

    I'm pretty sure if I set that up on the 2600 router that should work...

    thoughts?
