Backup default route for MS350

Backup default route for MS350

We have two internet connections, one Comcast fiber and one FIOS.  Right now, our default route goes through the Comcast fiber.  I've set up two ports on the MS350, each is a trunk that connects to either the fiber or the FIOS.  Then there's a VLAN for each with an interface created for each VLAN.


VLAN 10 = Comcast fiber - int vlan10 = = actual physical int configured as trunk

VLAN 11 = FIOS - int vlan11 = = actual physical int configured as trunk


The default route is go to via Comcast fiber, which is working perfectly fine.  When the fiber goes out, on our old Catalyst switch, I had a backup static route with a higher metric for that went our FIOS when Comcast went down.  I don't see how to do something similar on the MS350.  Yes, it's layer 3.

The MS350 switch is a Layer 3 switch, but it does not support the same level of routing functionality as a dedicated router or Layer 3 switch like the Catalyst series.


In your case, you want to set up a backup static route with a higher metric for when the primary connection goes down. Unfortunately, this feature is not available on the MS350. The static route on an MS350 is a global setting and affects all devices.


As a workaround, you could consider using a more advanced router or firewall that supports policy-based routing or failover functionality. This device would be placed between your MS350 switch and the internet connections, and would handle the decision-making process for which path to use based on the availability of the internet connections.

Agree with @alemabrahao. You need something upstream from your LAN switches to make this routing decision.  Is there no perimeter firewall in place here?
