How to Check BGP Advertised Routes on FortiGate
An administrator wants to verify that a BGP route is being advertised to a neighbor. Which command displays the routes that FortiGate is advertising to a specific BGP neighbor?
Quick Answer
The answer is `get router info bgp neighbor <ip> advertised-routes`. This command is correct because it directly queries the FortiGate’s BGP routing table for the routes that have been selected for outbound advertisement to a specific neighbor, filtering out any routes that are suppressed by policies or path attributes. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your ability to distinguish between verification commands: a common trap is confusing this with `get router info bgp network` (which shows locally injected networks) or `show ip bgp` (a Cisco equivalent). The key concept is that BGP advertises only the best path after applying outbound route maps and prefix lists, so this command confirms exactly what the neighbor will receive. Memory tip: think “advertised-routes” as “outbound truth”—if you want to see what you’re sending, use this command.
⚠ Common exam trap
Many candidates confuse the FortiOS 'get router info bgp neighbor <ip> advertised-routes' command with Cisco's 'show ip bgp neighbors <ip> advertised-routes' or mistakenly use a generic 'show ip bgp summary' command, which only shows neighbor state and not the actual advertised routes.

Correct answer & explanation
✓
get router info bgp neighbor <ip> advertised-routes
The command 'get router info bgp neighbor <ip> advertised-routes' is the specific FortiOS CLI command that displays the BGP routes that the FortiGate has advertised to a particular BGP neighbor. This command queries the BGP table for routes that have been sent to the neighbor and are in the Adj-RIB-Out, which is exactly what the administrator needs to verify outbound route advertisement.

Variation 1. An administrator configures BGP route advertisement but the routes are not being sent to the neighbor. The BGP session is established. What is the MOST likely cause?
medium- A.The BGP administrative distance is set too high
- B.The BGP neighbor has the wrong update-source interface
- C.The route is filtered by a route-map
- ✓ D.The 'network' statement is missing for the desired prefix
Why D: The BGP session is established, so Layer 3 connectivity and TCP port 179 are working. The most common reason for routes not being advertised to a neighbor is that the 'network' statement is missing for the desired prefix. In BGP, the 'network' command does not advertise the prefix unless it matches an exact route in the IP routing table; without it, BGP has no prefix to send, even if the session is up.
