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.

By default, ENDS is disabled.
On an ENDS-enabled tunnel interface, you
can use the evi neighbor-discovery client
enable command to add one more ENDS,
and use the evi neighbor-discovery client
register-interval command to modify the
ENDC registration interval.
4.
(Optional.) Enable ENDP
authentication.
