FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes the BGP router-id update process.
Scope
FortiGate.
Solution
The FortiGate updates the BGP router-id if the router-id has been updated manually using the command:
config router bgp
set router-id x.x.x.x
end
However, if the router-id has been applied automatically, and if that IP is not available now on the FortiGate the router-id is updated by the BGP process only when the following steps have been done.
The device is rebooted.
The process <bgp> has been manually restarted.
Example: If the router-id has been selected automatically, which has been explained in this article: Technical Tip: BGP router-id selection criteria on FortiGate and any one of the loopback interfaces IP has been selected for the router-id and now that interface has been deleted, and the router-id is not updating in that case, rebooting the device or the process is required.
