Configuration Mode Commands : SteelHead configuration commands : in-path peering-gre enable
  
in-path peering-gre enable
Enables generic routing encapsulation (GRE) auto discovery for IPv4 tunneled traffic.
Syntax
[no] in-path peering-gre enable
Parameters
None
Usage
Enter this command on all SteelHeads to enable GRE tunnel optimization support. This feature optimizes GRE traffic by extracting and optimizing the data behind the GRE header between the two WAN links. The default route for the client-side and server-side SteelHead should be directed to the WAN side of the network. Before the introduction of this feature, GRE traffic was relayed and not optimized.
GRE optimization supports hub-and-spoke and spoke-to-spoke topologies. A maximum of 100 tunnels are supported on a hub-and-spoke topology or with a spoke-to-spoke topology.
See the SteelHead User Guide for more information.
