FTD BGP Question

N3om — Mon, 09 Mar 2026 08:39:09 GMT

If I have a route based VPN configured on my FTD and I want to run BGP with the peer device then what IP address do I use for the peering is it the peers VTI IP or the peers interface IP address please.??

Thanks

@N3om You'd configure BGP to peer with the peer's VTI/tunnel IP address.

@Rob Ingram Does the other side peer with my VTI IP address ??

@N3om yes they would peer with your VTI ip address.

@Rob Ingram DO you know if other vendors Firewalls would see the VTI IP address e.g Fortigate, Palo

@N3om you can send the tunnel IP address to the peers from the FTD, but I am not sure if a third party firewall/router will process that or not tbh. Else, the peer firewall could just configure a static IP address.
