Hi Folks,
I have attached a screen capture of a PVST topology, could somebody please explain how f0/2 on SW4 becomes a root port? I'm under the impression that it should be an alternate port because SW4 has a lower MAC address value than SW2. Plus, t...
Hi Folks,
I'm trying to gain a better understanding of the STP process. I'm all clear on root bridge, root ports, designated ports but I'm confused about the block ports (alternate port). I've attached a screen capture of an STP topology showing that...
Hi folks,
If I explicitly configured a "router ID" on a router running OSPFv3. Is it still necessary to configure a loopback interface? What happens if I do not have a loopback interface? Would OSPFv3 not operate?
Another question on loopback inter...
Hi folks,
Could someone please share some thoughts on "auto-cost reference-bandwidth" vs" ip ospf cost value"
I'm thinking this isn't quite necessary to configure, could you tell if it's best practice not to change the bandwidth at all? Is there any ...
Hi folks,
When I setup STP on a switched environment with UplinkFast, would there be any foreseeable problem when I implement BackboneFast in conjuction with it? I haven't seen any docs suggesting UplinkFast + BackboneFast should not be implemented a...
Hi Spooster,
This is highly informative, massively appreciate it!
1) Could you tell how you determined that Fa0/2 has the lower port priority than Fa0/3?
2) I see it says "image result for layer 2 network diagram" But I'm not seeing any image, were ...
Hi Spooster,
It is indeed helpful! Appreciate it. I do have follow-up question thought. J
1) Are you advising that every non-root bridge should have a root-port? You explanation is clear when you say "fa0/2 is the root port (best path to root switc...
Hi Spooster, thanks for your feedback! I understand your explanation but it's still puzzling.
As you conveyed, root port is elected with the lowest Path Cost towards the rootbridge, so if we do the math, f0/2 on SW4 has 23 Path Cost towards the rootb...
