I am using 2 static routes to the same destination network at my HEADOFFICE, one primary and one for backup. I want them to have the same preference so I have kept the default adminstrative distance. One Interface is high speed and the other is slightly slower.
At the REMOTE BRANCH sites I would like to have the same arrange with 2 interfaces and routing the traffic to the HEAD OFFICE using 2 static routes , 1 for Primary and 1 for backup. But in the case of the REMOTE BRANCHES I will prefer routing over the faster link and increase the administrative distance for the slower backup link.
I will use IP SLA MONITOR feature on the REMOTE BRANCH routers to automatically control traffic in case of Primary link outage.
My worry is that at the HEAD OFFICE ROUTER. What will the effect of having 2 equal cost routes to to the same destination? How will Traffic from HEAD OFFICE be routed ? Since I m using IP SLA MONITOR at the REMOTE BRANCHES it is able to choose its path to take in case of outages in the cloud.
Since both static routes in the HEAD OFFICE have the same equal cost and will be load balancing. which Path will traffic take. Does load balancing mean traffic will distributed equally over the 2 links or halved. One halve going over 1 primary link and the other halve over the backup link? Or does this mean in static load balancing traffic all network traffic is duplicated over the 2 links?
