GRE Header Compression

Oracle SD-WAN Edge release 2.3 provides GRE header compression support, allowing for less additional overhead per packet when the customer uses the GRE protocol through the Oracle SD-WAN Edge. When compression is enabled, the GRE header compression will reduce the GRE overhead of packets from 24 bytes per packet to 7 bytes per packet. GRE header compression is performed by default, and is supported with and without GRE checksums.
