Hi all, We are working in an environment with CS 4.5.2 / XenServer 6.5 with multiple zones (Spain and Netherlands) using GRE Isolation and we have some concerns that we would like to share with you. Basically, we make a CPU benchmark between VLAN isolation and GRE isolation and the results show us that the consumption of CPU with GRE isolation is too much compared with VLAN isolation.
Can anyone share with us the experience working with GRE isolation? We are not sure if this configuration in production will be safe, scalable and with an acceptable level of performance. Thanks, David
