Symptoms

Currently the secondary address setting is not enabled for VXLAN tunnels.

Impact

The setting is useful in scenarios where remote VTEPs are unable to dynamically re-learn IP address, MAC address, and endpoint associations upon failover events.

Conditions

VXLAN tunnels are configured.

Workaround

None

Fix Information

This change enables the configuration of the secondary address setting for multipoint VXLAN tunnels. When setting the secondary address a multipoint VXLAN tunnel, the tunnel creates an additional endpoint, the secondary endpoint. This is associated with the local-only traffic group and sources tunnel flows carrying monitor and host traffic. This endpoint is created in addition to the local address endpoint which is used to encapsulate frames associated with the configured tunnel traffic group.
