-------------------------------------
Have a project and need my help?

-------------------------------------

Hey there, tech lovers!

We all know how crucial a steady internet connection is these days, right? Well, imagine if you could say goodbye to those frustrating internet outages for good.

In this video, we're tackling the awesome world of network reliability with a deep dive into Cisco's Dual ISP Failover.

We'll walk you through:
- Setting up a primary and backup internet service provider (ISP)
- Making sure your network automatically switches to the backup when the primary one goes AWOL
- Switching back as soon as your main ISP is back in action
- And a few cool advanced tricks and troubleshooting tips

No matter if you're a network pro or a tech newbie, this tutorial's got something for everyone. You'll come out the other side knowing how to keep your network online no matter what your ISP throws at you.

This is gold! Thank you! Please keep them coming like these ones

Wow, this is exactly what I needed. I thought I was going to need two routers with HSRP. This will save me a lot of money. Thank you!

Thanks. I have a Cisco 3560 switch at home. I used the sla and track configuration. Tested and it worked. I have a MicroTek router connected to Gi0/1 on the switch and that then goes out to the primary ISP. The secondary is Gi0/24 and that connects to an old Wifi router (wifi disabled) ... and then out to 2ndary ISP. This config is just what I needed.

thank you so much David, it is very professional and easy to understand .

2 questions: 1- does it is possible add a VPN setup here to take advantage of the failover and 2- when it should be used other routing protocols like OSPF or BGP?

Quick question though, I see you cleared nat table after the interface goes down, but somehow the NAT translation does not have to be cleared when the primary link comes up. What's reason for that? Thanks..

[Grumpymonk]

is it possible to do this if your secondary ISP(starlink) is on a different vrf? how difficult is this? could you please do a video regarding that?

[ReneKubicka]

Would you know, please, if your Cisco router sends/receives any data through the failover WAN while using primary WAN? I am using metric cellular data plan for my failover WAN. My current non-Cisco router continuously sends and receives small amounts of data via failover WAN (I assume pings) and therefore unnecessarily consumes my data plan. Can a Cisco router be so configured, that the failover WAN is in complete standby mode and no data at all will be sent/received unless primary WAN failure?

Thank you for sharing this great video.

Great explanaition! What if ISP IP set by DHCP? Possible to use port and not IP?

[Sabs]

hi @IT Solutions Network does it is possible to monitor more that only one ip (isp 1 or 2 ) on the interfaces? that's because what happens when google get down for it self?

[hyacinthnnaemeka]

Thanks for the KNowledge
can we have the configuration as a file

[Bogmrh]

How would we do this for router that's running S2S VPN and internet traffic? Is there a way to track both?

[DinoLopez]

Brilliant, thank you for sharing. Question how could ge leverage some non critical traffic to use backup Internet, such as maybe FTP, SMTP, RSYNC for slow backups, while both connections up. this way have primary failover backup, and some backup failover primary. Also what version of IOS is required for SLA.

Hello again, could you please do a video where the secondary failover is Starlink which is in different VRF please? thanks!!!
