Load Balancing Based on Odd and Even MAC Addresses

This section describes load balancing based on the odd and even media access control (MAC) addresses carried in user packets.

Figure 1 Load balancing based on odd and even MAC addresses

As shown in Figure 1, two Virtual Router Redundancy Protocol (VRRP) groups are deployed on the access side. One VRRP group uses NetEngine 8000 F 1 as the master and NetEngine 8000 F 2 as the backup, and the other uses NetEngine 8000 F 2 as the master and NetEngine 8000 F 1 as the backup.

In multi-device backup scenarios, configure load balancing based on odd and even MAC addresses to enable the master NetEngine 8000 F to forward only user packets carrying odd or even MAC addresses.

To determine the forwarding path of uplink traffic and prevent packet disorder, the master and backup NetEngine 8000 Fs in the same virtual local area network (VLAN) must use different virtual MAC addresses to establish sessions with hosts.
