Example: Configuring DRNI with MDT-based MVXLAN

Network configuration

As shown in Figure 1:

· Switch A, Switch B, Switch C, Switch D, and Switch E are distributed EVPN gateways.

¡ Leaf devices Switch A and Switch B form a DR system through DRNI, and they use the IPL to synchronize MAC and ARP entries to ensure MAC and ARP entry consistency. In this example, an Ethernet aggregate link acts as the IPL.

¡ Switch C and Switch D form a DR system through DRNI, and the DR system acts all the roles of spine, border, and leaf. In this example, an Ethernet aggregate link acts as the IPL.

¡ Switch E acts as a standalone leaf device.

· Switch A and Switch B are connected to VM 1 and VM 2 through Ethernet links. On Switch A and Switch B, the Ethernet links connected to the same VM are aggregated into a Layer 2 aggregation group to avoid single points of failure. Connect Switch C, Switch D, and VMs in the same way Switch A, Switch B, VM 1, and VM 2 are connected.

· VM 1 is the multicast source. VM 2, VM 3, VM 5, and VM 6 are multicast receivers in a private network. VM 4 is a multicast receiver in the public network. They use MVXLAN to transmit multicast traffic.

Restrictions and guidelines

· The member devices in a DR system must use the same DR system MAC address. Different DR systems must each have a unique DR system MAC address on the network.

· As a best practice, run a dynamic routing protocol between the spine devices and the external network. If you use static routing, rebooting spine devices might cause traffic interruption. For example, traffic interruption occurs if the service modules that provide IPP member ports, keepalive interfaces, and DR interfaces start up slower than other service modules. To resolve the issue, use one of the following solutions:

¡ Assign ports operating at the same rate to the IPPs on all service modules to ensure that the IPPs are always restored first. If the member ports cannot operate at the same rate, use the link-aggregation ignore speed command on the IPPs to ensure ports at all rates can be selected. In this solution, hash congestion or uneven load sharing might occur.

¡ On the spine devices, configure a monitor link group. To ensure that the uplink interfaces always start up earlier than the downlink DR interfaces, assign all downlink DR member ports to the monitor link group as uplink interfaces and assign all uplink interfaces to the monitor link group as downlink interfaces. The maintainability of this solution is weak. When you add, delete, or modify DR groups, you must update the uplink interfaces of the monitor link group accordingly.

· All ACs must be dual-homed to the DR member devices. Singlehomed ACs are not supported. Multicast traffic load sharing is not supported. The IPL can only be an Ethernet aggregate link.

· MVXLAN supports only IPv4 underlay networks and IPv4 overlay networks in the current software version.

· As a best practice, create frame match criteria based on VXLAN IDs for the dynamic ACs on the IPL.

· As a best practice to ensure correct traffic forwarding, do not allow IPP s or DR interfaces to forward traffic in the VLANs to which transport-facing interfaces are assigned.

· When a device plays all roles of leaf, border, and spine, packet loss occurs if the multicast source is on the public network and the receivers are attached to ACs in VPN instances. If such multicast traffic exists, do not configure a device to play all roles of leaf, border, and spine.
