One doubt: When calculating the cost of a nonroot switch to the root switch... do you add only the costs of outgoing interfaces on the path from the nonroot to the root or do you add the cost of all interfaces in every segment? I hope my question is clear.
I am reading a book that shows an example were they add only the outgoing interfaces in the path from the nonroot to the root. That confused me.
So, what you really do is add all the costs of interfaces in the path to the root. For example: If You have SW Root ---- SW1 ----- SW2 (all with FastEthernet - considering default costs), then the cost from SW2 to Root would be 19+19+19+19?.. is that right?.
Or... SW2 receives a BPDU form SW1 with cost of 38, then the cost to reach Root would be 38 (received BPDU cost) + 38 (the cost of the two interfaces in the link from SW2 to SW1).... is that right?
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
