I have a problem with a college assignment and would massively appreciate some advice
The assignment focuses on the hierarchical model, vlans, trunking. It states:
3 sites each with three departments (the departments are different in each site... no site has any matching departments so 9 deps all together)
I have partially done the assignmnet on packet tracer as so:
2960's for access layer each with two fast ethernet aggregated links to a 3560 (each site has one 3560 except for one that has 2 due to limitations on link aggregation and forwarding rates)
I thought this was good so far (and still do) but it came to the core devices and I wanted to use switches ( due to the theory on latency... layer 2 (OSI) traffic is a lot less burden than layer 3 etc).
I have read in the assignment brief that each site has an existing 2800 series (with 1 fast ethernet port and 1 serial port).
THE QUESTION IS......
What do I do?? Because at all sites that have 1 distribution device (3560) all the internal traffic in the site will not need to go to the core layer, the routing (within the site) will be handled at distribution..... so does this mean I could use this 2800 at the core. If this will work, can I, at the site where there are two 3560 distribution L3 switches can I just have a trunk link straight from one to the other???
Otherwise is my only choice (if I have to use this god damn 2800) to put a L2 at distribution then use the 2800 as a router on a stick (lolipop router)???
Some of the stuff I have said might be a bit lacking in knowledge, but please forgive me, Im still learning!!
