    wonderful examples, Im glad google is indexing this... hopefully other guys will find it.

    My vrrp config was not working because I hadnt setup the vlt peer port channel... seeing the entire script showed me where I had messed up.

    Is STP necessary? The way I understood is that F10 recommended to set it up initially in order to avoid the possible loop at the beginning of the config.

    I thought VLT eliminates the necessity of STP. Is this true?

    Thanks for posting!
