I'm very thank you for helping me out. Your lecture makes me understanding what the GARP is exactly and then I could solve my customer network problem. About this GARP issue, I was arguing with the Alcatel vendor engineer and then I won. That issue is belong to the Alcatel backbone switch not Alteon L4 switch. Thanks a lot.
Man, apart from your great explanation one thing I must say listening to your voice is like listening to some music. Even some nonsense thing will sound sense in your voice. Great comm skills😊😊😊
very good video. excellent. i thought youd tell something about the gratuitous arp for hosts. how to update the arp cache of a host with no arp request sent
That's what most people know about and typically expect... when considering a virtual IP the IP to MAC mapping does not change. The location of the MAC & IP , moving from router A to Router B does change.
I have a question. In the event of Router A going down, B taking over and sending broadcast, wouldn't Switch 1 have multiple entries of same MAC A.B.C (one entry from Port 1 connected to Router A, other entry from Port 2 connected to Switch 2) ?? Hope my question was clear !!
Hi Ryan, thank you for the wonderful explanation. This surely helps. I have one question though. How does request for 10.1.1.1 sourcing from the PC is sent to R1 in the very beginning? How does the switch 1 know that A:B:C (i.e. the virtual MAC) is on it's port 1? Is that because there is gratuitous ARP from Router 1 as well at the very start?
ok, switchs mac table is updated...but in what way? did new path simply overwrites old one? or there will be two destination for one mac for some amount of time
It updates the MAC address table. The rule is the most recent information is the best information. Interesting when attackers spoof a MAC address that's in use elsewhere.

Very clear and great explanation Ryan...thanks !!!
Simply brilliant!!!!!
Very clear, thank you. Is it an ARP reply or an ARP request?
It's a "gratuitous arp reply", gratuitous because you didn't ask for it, it was "unsolicited". Hope that helps!
