Description | This article provides a workaround for an ongoing issue on the FortiGate-80F-DSL installing /8 connected route. |
Scope | FortiGate-80F-DSL |
Solution |
An issue occurred on FortiGate-80F-DSL tested with v7.0.15, v7.2.9, v7.4.4, and v7.6.0 where the FortiGate is advertising a connected route of /8.
Sample routing table:
Routing table for VRF=0
This might cause an issue to have this /8 subnet traverse on another WAN interface.
Workaround: Create two /9 static routes to override the /8 connected route. As /9 is a more specific route than /8, then it will override the current behavior where /8 is automatically installed.
To configure static route:
In CLI: Create the 1st Subnet:
config router static edit 0 set dst x.x.0.0/9 <----- Enter the Network Address of the connected route having an issue. set gateway Y.Y.Y.Y <----- Enter the Gateway IP. set device *outgoing interface end
Create the 2nd Subnet:
edit 0
In GUI: Go to Network -> Static Routes and select Create New.
