Hey guys, there is a slight mistake in the video when explaining VRRP protocol, the VRRP does not return the Physical MAC address of the host but returns a virtual mac address called IANA mac (looksl ike this 00-00-5E-00-02-{VRID}) From the RFC tools.ietf.org/html/rfc3768#section-8.2 lots of network engineers have pointed to me (thank you) and I wanted to correct that, Here is a new video to explain that, the rest of the video is still correct only that portion isn't th-cam.com/video/Jlxu7SRI6Cw/w-d-xo.html
I have to correct you here. VRRP uses a virtual MAC, so if AAA goes down, the client will not send an ARP request, it will continue to send to the same virtual mac, and host BBB will take the responsibility of replying to this virtual mac. "A virtual MAC address is generated by the virtual router based on the virtual router ID. The virtual MAC address format is 00-00-5E-00-01-{VRID} (VRRP) and 00-00-5E-00-02-{VRID} (VRRP6)."
If i have at home 2 machines with public ip, what would be my "virtual ip" -> "floating ip"? I need it to be public because i want access some web page on server 1 or server 2. What do I have to ask internet provider for? Additional public ip? And then i configure keepalived on both where my virtual_ipaddress is that new public address? I have 2 nginx load balancers with both of them configured with keepalived + upstream is made of 5 app servers. 2 load balancers have public ip. But what is then virtual_ipaddress?
Nice video ;-) I want to create a VIP for two Active/Passive servers but the problem is the console of this App (Dollar Universe) works with specific 4170 port... Do you know how could I specify to my VIP that works with this port or redirect to this IP_servers:4170 ports???
Hi Hussein, a good example of VIP interfaces but I have a doubt, Does can be possible a VIP interface when the two servers have different segment networks and a router between them.

“Call it! Call it!” This guy is awesome at explaining things!
If you can't explain it simply, you don't understand it well enough!... Hussein obviously understands this well. Great explainer video.

Thanks George someone pointed the same as well. Appreciate the correction 🙏
This video should belong to your playlist "Network Engineering"
Thank you. THANK YOU!!!!
Great explanation about Virtual IP & VVRP

Just subscibed - excellent content! Keep up the good work!

Excellent stuff keep it up.
Hi Hussein, a good example of VIP interfaces but I have a doubt, Does can be possible a VIP interface when the two servers have different segment networks and a router between them.
no they must be on the same l2 subnet
bismillah.. can you tell me how to set Load balancing using VIP addres ?
that was cool!
Well explained
Subscribed. Great content.
Welcome aboard!
Is it possible to find the VIP from DNS? If so how?
William H yes if the entry in the DNS used is the VIP then you can issue a DNS query or just ping the DNS entry
nice.... ok .... good job..
Merci
Broo ur crazyyy😂😂😂
