Hi,


Sounds like my earlier post was not clear on this topic.


There are 3 IPSEC GRE Tunnel between Site_A to Site_B with EIGRP as routing protocol


On Site_B each IPSEC GRE Tunnel is with different ISP on the Same Router.


But traffic flows only from tunnel which has a static entry to destination public IP.

How to tune the config to make all tunnels active and send traffic when other tunnels are down or possible a load balancing scenario.


Is this possible.

Hi, Based on some reading I am sure DMVPN can do this.


But I am keen to understand will it work as I mentioned.


If more information is needed in terms of config, I can upload.

Thanks for the support.

Tunnels are terminated on Routers at both end. Have a look at attachment.


In Common scenario with one Service provider terminating on Router we have

ip route 0.0.0.0 0.0.0.0 192.168.4.1


If I have three ISP terminated on same router with sub-interfaces and have 3 GRE tunnels then what needs to be tuned to make it working.
