    question about proxy-arp

    mls question

    I think MLS is working.If I "show mls" or "show mls entry",it display normal. So I can't understand why it is working normal even if mls flow mask is Destination flow and my msfc2 is configured with extented ip access-list. This is my question. thanks!

    mls question

    I got it from cisco.com. CAT3550/CAT6000 with Sup2/MSFC2, CAT4000 with Sup3/4 uses CEF based forwarding. CAT6000 with Sup1/MSFC support MLS only CEF is a enhanced implementation of MLS. With MLS, the first packet hits the router to get routed and then subsequent flows are hardware switched...

    spt diameter

    somebody told me: diameter of the STP domain is defined: The maximum number of bridges between any two points of attachment of end stations. See http://www.cisco.com/warp/public/473/122.pdf for details. So my network diameter is 3. thanks everyone!

    spt diameter

    Sorry,correct answer is 3. The diameter is the number of switch ( include itself) between any two switch.
