For this release, we completed our dynamic routing protocol suite by supporting BGP. Similar to OSPF, we take configuration from Cisco ACI L3Out with BGP configuration and program FortiGate accordingly. Please note that only iBGP is supported based on Cisco ACI’s supportive matrix. Configuring ACI L3Out is beyond the scope of this document, however below are some screenshots which can guide you through the configuration.
- vrf name
- routed romain
- routing protocol
Define the node information as well as the BGP peering information.
Define the L3 out interface information.
For IBGP, there is no need to define Remote AS Number. The Local AS number is taken from the Route Reflector AS number. (For details on how to configure Route Reflector AS Number, please consult Cisco ACI document.)
