OSPF Routing how to prioritize interface vs tunnel

This can be achieved by setting “cost” associated with the interfaces.  If a route is learned via two interfaces, the path with a lower cost would be preferred.

Cost of an interface can be set as follows:

Under OSPF configuration, in the “Override Interface section”, for the relevant interface, disable the “Autocost” and configure the cost values such that the overall cumulative cost of the preferred route is lesser.

Thanks,

Upon testing, I've discovered that the changes that I made have not resulted in the expected outcome.

Site 1

prefered interface cost =1

XFRM interface cost = 5 

Site 2

prefered interface cost =1

XFRM interface cost = 5 

Our routers still prefer Broadband gig XFRM VPN interface over dedicated fiber GIG.  Not sure how / why it believes that our backup connection is better quality.

OSFP convergence / route change is taking about 3 min if I turn off one of the active interface.  IE: connectivity goes down, while OSPF decides to switch path.  I changed Hello and Dead intervals from 10 / 40 seconds (default) to 2 and 8.  No significant change in convergence was observed.

I'm wondering if we should SD WAN, and see if it functions better for us.  I need to figure out if SD wan can be re-distributed to OSPF.

Would like to take a look at the device to analyse, can you please provide support access details in private Message to me?

Thanks. 

I will do a create a case with pictures, then PM.
