ADVPN BGP Multipath routing

Hi All, 

 

I've built a lab with SD-WAN ADVPN set up over an MPLS network, with an Internet VRF and a Private VRF, all looks to be working fine, except for BGP multipath routing. 

 

I have a Server IP, learning the IP through BGP over both Hubs not a problem, with the preferred path entering the routing table, however, I thought with multipath routing it would install both routes in the routing table?

As a result, my SLA to the server in SD-WAN is showing as down over 1 of the Hubs, so it can't flip over if packet lass or high latency occurs etc

 

Any ideas please?

 

Thanks in eager anticipation

Hey Anthony, 

 

Thanks for the update, looks like I've managed to sort it now. I had a BGP peering for HSCN running into the Hub FortiGates too, I segmented that into it's own VDOM instead which has now solved the problem. 

 

Thanks
