hey guys, hope somebody have some input on this type of situation.
So, we have 3 offices, A is head office and B, C are remote sites.
*All connected via wireless and all on different VLAN
We’ve had issues with our WAN provider so we’re looking to add some redundancy. My initial thought was connect B -> C with a MPLS service and have a WAN ring so that when C -> A fails, traffic gets re-routed through B to A. I’ve thrown that to our network consultant but he seem to think we can’t do it because the router at B and C only has 1 WAN port (cisco 1800 series). I’ve looked at our 1811 at headoffice and can see there are 2 WAN ports, so if we throw 2 other 1811 or above routers to the remote locations, would this design work? Finding more reliable WAN provider is out of the question since we still have a pretty long contract to go. Any suggestion is appreciated.
