I'm Angela, and this is my first post here in CSC, got some design implementations problems. I am reading Cisco LAN switching by Clark and Hamilton, published in 1999. Not the greatest book for latest technology, but I do find a lot of design tips to be very helpful. Here we go:
1- What is your ideal OSPF area versus IP addressing plan?
2- The book I mentioned above suggested using L3 switches as core switches, I've also seen some L2 cores. Please comment on the pros and cons of each
Got some technical questions as well:
1- Does software-based broadcast suppression is still around? If so, please tell me how to configure it
2- What really triggers a switch port to enter listening state (from blocking)?
3- Here is a point from the book (not exact wording): "A TCN BPDU is generated when a port moves to forwarding state and the switch has a Designated port", why does a Designated port has to be around for a TCN BPDU to be generated because a port moves from blocking to forwarding?
Thanks for all comments,
