Before imnplementing your solution, all tunnels were already up using GRE over IPSec indeed.
After adding your EIGRP commands, there is communication between all these 3 routers and also redundancy. I took down the first 1841 and the 10.200.200.0 network (the network behind the 1841s) was still communicating with the 10.10.50.0 (the network behind the 2811). This is very good.
Now I need some fine-tuning. There is an issue where the internal hosts (10.200.200.0) send their packets out to the servers at the hub and the GLBP is doing its job, however, when those packets hit the first 1841, they get re-routed back into the 10.200.200.0 network and out to the second 1841 and then from there the 2nd 1841 sends it to the destination (10.10.50.0)
So, load-balancing is not happening as all traffic destined to 10.10.50.0 gets out via the 2nd 1841 as opposed to both. I assume this is so because of the priorities on the router's route tables? In other words, the first 1841 has routes to the 10.10.50.0 but because the route via the 2nd 1841 has better metrics, it uses that route. Thus, only one router is being used to send out the traffic to 10.10.50.0
I played with the commands nd found the passive interface one.
What I did was not to advertise the routes on both of the internal interfaces of the 1841s. This way, its route tables only have one route towards the destination network 10.10.50.0. This is exactly the fix for the issue because we only need one route towards the destination on each of the 1841's. GLBP is already taking care of the load balancing and redundancy; if one 1841 goes downs, the other still up and all traffic towards the desti. will continue to flow via this other 1841.
Giuseppe thank you for your inputs... helped get this up...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
