drni mad exclude interface
interface-type interface-number
By default, DRNI MAD shuts down all network interfaces when detecting a multi-active collision,
except for the network interfaces set by the system to not shut down.
Configuring a DR interface
Restrictions and guidelines
The device can have multiple DR interfaces. However, you can assign a Layer 2 aggregate interface
to only one DR group.
A Layer 2 aggregate interface cannot operate as both IPP and DR interface.
To improve forwarding efficiency, exclude the DR interface on the secondary DR device from the
shutdown action by DRNI MAD. This action enables the DR interface to forward traffic immediately
after a multi-active collision is removed without having to wait for the secondary DR device to
complete entry restoration.

Specifying a Layer 2 aggregate interface or
VXLAN tunnel interface as the IPP
Restrictions and guidelines
A DR member device can have only one IPP. A Layer 2 aggregate interface or VXLAN tunnel
interface cannot operate as both IPP and DR interface.
Do not associate a VXLAN tunnel interface with a VXLAN if you use it as the IPP. You can use a
VXLAN tunnel interface as an IPP only in an EVPN network. For more information about EVPN, see
EVPN Configuration Guide
.
As a best practice to reduce the impact of interface flapping on upper-layer services, execute the
link-delay
command on the IPP. For more information about this command, see Ethernet link
aggregation commands in
Layer 2—LAN Switching Command Reference
.
By default, MAC address learning is enabled on the IPP. This feature is not configurable on the IPP.
For more information about the MAC address learning feature, see "Configuring the MAC address
table."
To prevent data synchronization failure, you must set the same maximum jumbo frame length on the
IPPs of the DR member devices. For more information about jumbo frames, see "Configuring
Ethernet link aggregation."
Do not use the MAC address of a remote MEP for CFD tests on IPPs. These tests cannot work on
IPPs. For more information about CFD, see
High Availability Configuration Guide
.
