Advertising networks to 5 remote sites via Site to site VPN
Hello fellow Merkai Nerds,
We need some help.. Here is our scenario:
We currently have 2 Meraki MX250 devices running as hubs. We would like to create a second link to have a redundant path for network traffic if the primary hub was to loose connectivity (Power outage, loss of carrier service).
Hub 1 in on network 172.18.100.0/24 and advertises networks
We have 2 major site that run on networks 10.10.0.0/16 and 172.18.0.0/16. These sites are currently connected via a dark fibre network and using BGP to connect the 2 sites via another link.
Our VPN sites are on the network 10.10.210.0/28 using VLSM for these sites as we only require 14 hosts per site.
We have a second hub that is network 10.10.100.0/24.
When attempt to advertise the above networks via the second up, we create a routing loops. We have tried via OSPF with 2 areas, with the second are at a higher costing, but this still does not work.
What we are after is a second (redundant) path for these VPN devices to connect to the network if the primary site was to loose connectivity. Does anyone have a suggestion?
