Route priority 0 in Fortigate firewall

[zubair_ahmad]

Hi,

We have existing default route towards the ISP with route priority 0 and AD 10. i want to configure the another default route

for seondary ISP without any impact to the network.

if i use priority 0 for secondary ISP, will it add as secondary default route. i don't want to change AD value for both

It would load-balance if you have the same route to another interface with same distance&priority. Not sure what you meant by "without any impact to the network".

actually my doubt is what if we have have two ISP and having default route towards both the ISP , towards Primary ISP route priority is 0 and AD is 10 and towards secondary ISP route priority is 5 and AD 0, which one would be active.

just as addition to Ken: setting a second default route will not work if you use sd-wan hence sd-wan does the default routing on its own. Just to keep that in mind :)
