Hello All,I am looking for a simple logical reasoning behind a small thing that has been troubling me.Please refer to attached diagram to better understand this situation. I am going to ping PC-2 from PC-1 in different subnets and VLANs, with a prope...
Hi All, I have a query for you all, which you might be able to guide me on this: How does a switch/router, that receives bits on a link able to separate and create the packet back from the one sent by sender.For example a switch has received 010101.....
Hi All, I am wondering how does a network work around one MPLS label that gets generated on multiple devices. Is that a bad omen for your network or is it completely fine? If it is a completely fine phenomenon then how does the packet switching take ...
Hi All,I have two questions regarding OSPF virtual-links. Please refer to the attached topology to get a better understanding of what I am trying to emphasize. Question 1): Is OSPF virtual-link two way communication or one way?Question 2): Suppose a ...
Hi All,I just stumbled across an implementation where a customer seems to control outbound traffic using BGP MED. I want to confirm if that is entirely possible at all and if yes then how.Thanks in advance.
Hello @Georg Pauwen!Thank you for your reply. Respectfully, the amount of bits added by each layer is variable per protocols/standards running on that specific layer, an example of that would be IPv4 vs IPv6.I am waiting for others to contribute more...
Hi @Giuseppe Larosa,What amazes me about OSPF virtual-link is that the LSA does not get deleted. I see an ICMP unreachable message between tunnel source and destination and nothing else. After that the route gets deleted from RIB but the LSA is still...
Hi @Giuseppe Larosa: My sincere apologies for not understanding my own topology and how it would react around a failure. My router-IDs are same as their router number(R1 being 1.1.1.1 for example). In this case when R4 goes down, R3 will be elected a...
Hi @Jon Marshall, I agree with the point and this is exactly what a sane engineer would prefer to. We were talking about a side case and a singularity in this case. I have now evidence that it might be done, I just don't have the proof to cement my c...
