Step Command Remarks
5. (Optional.) Generate a GRE
key for tunneled packets
based on their VLAN IDs.
gre key vlan-id
By default, EVI tunneled packets do
not contain a GRE key.
The GRE key setting must be the
same across an EVI network.
Assigning a network ID to the EVI tunnel
Assign the same network ID to the EVI tunnels of all edge devices in an EVI network.
On an edge device, the network ID assigned to an EVI tunnel must be unique.
To assign a network ID to an EVI tunnel:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter tunnel interface view. interface tunnel number [ mode
evi ]
N/A
3. Specify a network ID. evi network-id number By default, no network ID is specified.
Specifying extended VLANs on the EVI tunnel
When configuring extended VLANs, follow these guidelines:
• You can specify an extended VLAN on only one EVI tunnel.
• To avoid loops, do not assign transport-facing ports to extended VLANs.
• To avoid data breach, make sure all edge devices in an EVI network maintain the same list of
extended VLANs.
To assign extended VLANs to an EVI tunnel:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter EVI tunnel interface
view. interface tunnel number [ mode
evi ]
N/A
3. Specify extended VLANs. evi extend-vlan vlan-list
By default, no VLANs are specified as
extended VLANs on any EVI tunnel.
To specify more extended VLANs, repeat
this step.
Configuring ENDP
ENDP enables the edge devices in an EVI network to discovery each other.
Configure an edge device as an ENDS to provide registration services or as an ENDC to register with an
ENDS.
