iBGP multiregion examples?

[lundgrenolof]

Hello, and thanks for the nice topologies including the configurations.
Do you have examples of iBGP multiregion like describedin Fortinet docs here:
https://docs.fortinet.com/document/fortigate/7.2.0/sd-wan-architecture-for-enterprise/242856/using-ibgp-between-regions-with-inter-region-advpn

I tried following the configuration examples from from you, but never got the cross region shortcuts working. region1spoke1 to region2-hub1 had valid routes and traffic was forwarded, however no shortcuts where built.

Hi,

I would recommend using EBGP between regions.
The Jinja Orchestrator supports Spoke-to-Hub shortcuts with Dynamic BGP design, you can generate the configuration by adding this variable to the Project file:

{% set spoke2hub_advpn = true %}

The resulting configuration should work.. there may be certain suboptimal switchover situations related to the fact that the Hub normally doesn't have ADVPN 2.0 enabled, but the shortcut itself should work.
