Hello, everyone. I am covering MSS at the moment and I've read that Cisco IOS devices set the MSS to 536 for TCP connections to remote networks. From R1 to R2R1#telnet 10.0.0.2Trying 10.0.0.2 ... Open*Jun 16 11:39:18.237: TCP0: Connection to 10.0.0....

Hello, everyone. I have 2 questions regarding dCEF and chassis devices as I just started learning about them. 1. I've read that there are Route Switch Processor cards in chassis devices which serve the same purpose as a CPU. My question is, what is a...

I've read that there can be several CEF adjacencies from NetworkLessons.com. I am a little confused. What does adjacency mean in this context? So far I know that there's an adjacency table which stores the L2 - L3 mappings and the pre-built Ethernet...

Hello, everyone! I've always been told that the routing table is a control plane concept. You build this table, collect the routes, the way they were learned, their metrics, and so on. You then use this information to build a more forwarding-suitable...

I was asking about why do Cisco IOS devices set the MSS to 536 for remote connections and what was the reason behind it which Joseph.W. Doherty answered, that's why I haven't picked your answer as the solution. I know how to configure the MSS and als...

Hello. Right, I completely forgot about this. Once I enable PMTUD by using the ip tcp path-mtu-discovery command, the Cisco router uses an MSS of 1460 (since 1500 is configured on its interface) now instead of 536 so that solves the problem, thanks g...

That's a fantastic response, thank you for taking your time to write this down plus provide the links!

Hello!Thank you for the reply. What queue are we talking about here? I thought that each traffic class has its own queue if we are running CBWFQ.

I was still a little unsure but your post together with the articles switched the lightbulb in my head ON.Although I wouldn't say that I am a RD/RT master now, I definitely understand the WHY behind these two.Thank you and everyone else very much. Yo...
