We are replacing all old IPSEC VPN tunnels with DMVPN.
We want to have two dual hubs and mutliple spoke. We have EIGRP
running on the hubs and then redistributing into OSPF.
This is the issue.
We have one hub as primary and one hub as secondary.
Everything works fine, but we've been running into an issue when one
of the primary hub goes down and comes back up, the amount of time it
takes for a spoke to see it is not consistent.
It goes anywhere from 2 seconds to 10 mins.
Besides that, everything works fine.
Is this by design?
