Description | This article describes that the SD-WAN static route is removed when downgrading from the v7.4, v7.2 or v7.0 stream to the v6.4 stream. |
Scope | FortiGate. |
Solution |
It is strictly recommended to upgrade the FortiGate using the Upgrade Path, but there are any unseen circumstances where the FortiGate needs to be downgraded to the previous version which is v6.4.x from v7.0 , v7.2 or 7.4. If the default route is using the SD-WAN interface, it will be removed due to the naming convention and this is expected.
Below is an example in each version:
v6.4.13:
config router static
V7.0.14:
config router static
edit 1
set distance 1
set sdwan-zone "virtual-wan-link"
next
end
V7.2.8:
V7.4.4:
Solution: In this situation have the console cable ready to access the device and add the static route back. |
