Hi Everyone!
My office has dual WAN connections (ISP 1 & ISP 2). Can I use interface aggregation for WAN failover?

Previously, I configured the WAN using Policy-Based Routing, but there is a downtime of 10-15 minutes due to BGP network propagation.

Here is my network topology:

hi, i not recommend to create an aggregate for wan interface as the firewall can detect if a wan is down and switch internet on the backup wan.

Interface aggregation typically combines multiple connections for increased bandwidth and redundancy, but failover might still experience delays, especially in BGP setups. For quicker failover, consider configuring dynamic routing protocols like VRRP or implementing an SD-WAN solution to manage WAN failover more efficiently with minimal downtime.
