Hi there,
I’m testing the DMVPN solution provided on the Link below:
https://whiskeyalpharomeo.com/2016/09/16/vyos-testing-dmvpn/
I’m facing a routing problem with routes redistributed from OSPF into BGP protocol as you can see below:

Can someone help me to understand if this is a bug in Vyos or a bad configuration somewhere?
