I'm a network geek and a security enthusiast. The labs/demos/lectures on this channel are from my personal notes which I have accumulated over the years working on some kickass technologies with super nice peers, reading books & attending trainings from reputed teachers in the industry

if you are having GARP and supress ARP, then what is the need to configure multicast ? once the endhost do GARP leaf using the control plane should send the info to other leaf and using Supress ARP endhosts can populate their arp table ? do you think without multicast it can work ?
Could you please continue this series with more focused on troubleshooting the real time issues. It would be very helpful for the people who wants to learn silverpeak sdwan and do certifications
FYI - 42:36, I had run the "show ip route" soon after the e0/1 was shut. Hence you see the 10.0.13.0/24 (connected route) has been removed from the routing table and the route from RIP hadn't arrived on R1 yet. RIP sends periodic updates every 30 sec so you will see 10.0.13.0/24 ( RIP route via R2) if you run the show command again post 30 sec.
Nice content. Another point is, in some cases, we need to limit ARP responses for a given eth segment. This result more strict routing policy and we need to define at least two RIB entry which they are more specific than our eth segment. We can point to null interface for more specific routes but this isn't a good idea, so we will point to a trusted intermediate hop. Now the problem is, router no more have a next-hop reachability, since our ARP limiting specific routes points to any random eth neighbor. The solution is to add exit interface in our more specific static entries. This will solve our routed networks reachability and any traffic destined to next hop itself but we have new problem, any another intermediate hop in this eth segment also need to static entry since we are still unable to point any directly connected entry.
I saw a few videos, your teaching skills are really awesome... teaching isn't matter how teaching is matter great is there any chance to start WLC and Wireless ?
Joyal is a fantastic engineer and a trainer who makes learning very easy, first by designing, secondly by explaining the lab layout and finally showing how to make the technology work. Thanks, Joyal for the mentorship you provide through these wonderful vlogs.
Hi Joyal, @ 13:40 , both wan interfaces were configured with INET1 labels for SP-4. However SP-4 had MPLS and INET profile. Doesn't it need MPLS+INET profile?
Thanks for your vids! The test drive SD WAN was already configured with some edges, how can I request one without any instances, like the one you show in the video?
Nice intro - but how can you automate the address attribution for the sites behind the edge? Can you read from a database? Can you add variables in the pre-configuration file?

Hi Joyal, thanks for this kind of content.. how can I download Cisco ios/sdwan os for labs.. should I have a contract or we can have any specific licence or free.. need advice on this pls..
