    I have a Cisco 2621 router that connects to a Allied telesyn fiber
    switch. I would like to segment my network into vlans/subnets however
    considering i only have one router it might be hard to do. I was
    wondering if i could use alias address on the Ethernet port so that
    the users on each vlan/subnet could use the same router?

    Thanks in Advance

    You could, but it would probably be better to use subinterfaces
    and trunk to the 802.1Q-aware switch.

    you'll need an IP plus ios image to support 802.1q encapsulation on the
    router, and it can become a router on a stick.

    Forgive my ignorance but how would i do that with 2621 router? Are
    those features available in the above mentioned feature pack?

    Do a sh ver. If you have something like c22600-i-mz.122- etc etc you have ip
    only. You need and IOS image with is-mz feaures (IP Plus). You would then
    have to upload it in to flash (make sures theres enough room), and boot from
    it. Then you can configure sub interfaces on fa ports. I not played with
    2600 much, more 3600/3700 and 7200, so not sure on specs.
