Encapsulation

Generic Routing Encapsulation (GRE) headers provide a private secure path for transporting packets.

You can configure outgoing-packets encapsulation with configured tunnel and L2 or L3 parameters. The following L2 and L3 parameter configurations are required for GRE encapsulation:

• Outer destination MAC address (mandatory)
• Outer source MAC address (mandatory)
• Outer VLAN Tag (optional)
• Outer VLAN PCP (optional)
• Outer Source IPv4 address (mandatory)
• Outer Destination IPv4 address (mandatory)

Note

The flags in the GRE encapsulation header are set to 0.
