Hi there,
The scenario is the following : there are 3 distant sites that need to be interconnected as in the image attached. On every site - there are 2 layer3 switches. 2 of the sites are interconnected via 2 telecom links an the third is connected to each of the 2 using one link.
The first 2 sites are datacenters and the third is a user site.
The question is how to use all the links in this topology in load balancing mode and avoid creating loops. If we enable Spanning Tree - it will brake all the loops, thus leaving only on channel between each site in active.
The price of these channels is very expensive and we would like to use them in active/active environment
Any help would be appreciated
