• An extended VLAN can be specified only on 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.
Configuration guidelines
• For redundancy, you can configure up to two ENDSs on an EVI tunnel interface. These two ENDSs
work independently. The failure of one ENDS does not affect the neighbor discovery and EVI link
maintenance in the EVI network.
• When you enable ENDS on an EVI tunnel interface, an ENDC is automatically enabled. This ENDC
uses the source address of the EVI tunnel as the ENDS address. As a result, you can use the evi
neighbor-discovery client enable command to add only one ENDS address on an ENDS-enabled
EVI tunnel interface.
• To guarantee that each edge device can obtain the addresses of all its EVI neighbors, make sure the
ENDSs are the same across the EVI network.
• To improve security, enable ENDP authentication.
{
Make sure all authentication-enabled ENDCs and ENDSs in an EVI network use the same
authentication key.
{
If authentication is disabled on an ENDS, all ENDCs, including authentication-enabled ENDCs,
can register with the ENDS without authentication.
{
If authentication is enabled on an ENDS, only authentication-enabled ENDCs that use the same
authentication key as the ENDS can register with the ENDS.
