Hi,
We have been tested 3810 in our lab and we have been tried to figure out if th 3810 supports GRE tunnels.
We have manged to configrure our system so that HP VAN SDN controller and HP Network Protector SDN application works as described in the Service Insertion Guide : ie. GRE tunnel is created automatically and it works.
But, is it possible to create GRE tunnels manually between two 3810 ?
