Usage guidelines

The GRE key setting must be the same across an EVI network.

Configure this command on an EVI tunnel interface if any remote edge devices generate VLAN ID-based GRE keys for EVI tunneled packets. The EVI tunnel interface accepts an incoming tunneled packet only if the GRE key in the packet matches one of the local GRE keys.

Examples

# Enable EVI tunnel interface 1 to generate VLAN ID-based GRE keys for tunneled packets.

<Sysname> system-view
[Sysname] interface tunnel 1 mode evi
[Sysname-Tunnel2] gre key vlan-id
