Hello,Can someone please confirm if this is correct?Topology:SW1–R1Switch 1 (SW1) is connected to Router 1 (R1) via an access link configured for VLAN 222. SW1 has an SVI in VLAN 111 with an IP address assigned for management purposes. SW1 isn’t conn...
Hello, I’d like to ask two questions about Wendell Odom’s explanation of RPVST+/PVST. The relevant pages are 245-246. Can someone please help me figure it out? 1.He says:“* RPVST+ adds an extra type-length value (TLV) to the BPDU that identifies the ...
Hello, Can someone please confirm if my reasoning is correct?: I believe the answer is C because on SW4, both interfaces lead through the SW3 to the root (which is SW1 due to its priority), and F0/11 has the highest number, so F0/2 is preferred ov...
Hello,I've got a question about STP/RSTP (it applies to both, but I'll just say STP). If I connect several switches and the STP algorithm eventually creates a loop-free environment, then how can a single new switch cause a loop?Let's look at an examp...
Hello, Can someone please help me with these subnetting problems? 1) Suppose you have the network 172.16.0.0/16. How many subnets do you get if you subnet it to a /23? I'd say you get 2^7=128, because 23-16=7. This calculator agrees with me, and it l...
Thank you both for the help!If I understand it correctly, the solution you have in mind is proxy ARP. And the way that would work is:1. On SW1, I configure an SVI in VLAN 222.2. On SW1, I configure proxy ARP on the SVI in VLAN 222.Then,1. R1 ARPs for...
I've re-read the thread again and would like to ask you again about your comment where you said " Because Switch 3 has a lower bridge ID than Switch 4 . They tie in the priority then the next step is the mac address and switch 3 has smalled mac addr...
Thanks again, I've marked your answer as the solution because you've addressed my original concern. Thanks for the other responses as well, I appreciate it!
Thank you very much for your help! I've marked Flavio's answer as the solution because he addressed my original question, but I'm very grateful to you as well for reinforcing my understanding of STP! If I could, I would mark your answer as the accep...
Hi.Thank you very much. On your topology, the port connecting switch IOU3 to switch IOU2 is in Blocking state; but if the port between IOU3 and IOU2, and IOU3 and IOU1 would be a Gigabitethernet port (instead of the current Ethernet port), wouldn't t...
