@@TheNetworkTrip So, can you set it on, say, a hap ac2 [I use it just as a switch at home too, and let a firewall doing routing and being a gateway to internet ]? By the way, what is the proper protocol for redundancy on switches? Thanks
Hellow nice video. Thanks. You enabled sync connections tracking on the higher priority router. In case of failure of this router the lower priority router knows about the current state of connections. But what about when the higer priority router comes back to life ? Does the connections tracking are synced back to the higher value before the virtual ip is switched back ? And second question in your topology the virtual ip is on the lan side, and it's working great for outgoing traffic but in 'real life' setup shouldn't be also a virtual ip setup on the wan side ? Thanks
Hello! If the router was unavailable, then, it won’t be synchronized (it was down). If you want to have VRRP at the WAN side, you will need another instance, the process is exactly the same.
VRRP provides redundancy for the LAN in this demonstration. If a physical issue occurs with the connection, VRRP messages will stop being exchanged. As a result, the backup router will detect the absence of messages from the master and take over the master role to maintain network availability. However, VRRP cannot resolve Layer 1 issues, so the physical problem must be fixed manually. If preemption is enabled, once the original master router’s connection is restored and it starts sending VRRP advertisements again, it will automatically reclaim the master role. The backup router will then return to its backup state, as preemption ensures that the router with the higher priority regains control when it’s back online.
@@TheNetworkTrip There must be a problem with my LAB then. The backup router continues to work as the "main" gateway even after the master's router connection is restored. In a few words, the connection doesn't switch back to the master unless I don't disable the backup router manually. I made sure that the preemption mode is enabled on both. Why?
Hi. I have two questions. What would happen if we put mask on vrrp address (for example /24)? And if we create vrrp interface for wan port, which interface will be used for out. interface on nat?
Hi Wilmer. Nice video. Can you create a VPN on both routers and create a site to site VPN with two paths?
Interesting. Can you set VRRP on two switches which run VLANs too? Thanks
Hello! VRRP is for routers, not for switches working in layer 2. If you have a switch working as a router, yes, it can be configured with no problem.

Ok, but what if it's a cable problem or port issue and the router is still up ?

Thank you very much.

can you explain with e.g. what mDNS does?
Hello!
I’m working on a video about that. It will be available soon.
