Load Balancing Based on Odd and Even MAC Addresses

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 8-26 Load balancing based on odd and even MAC addresses

As shown in Figure 8-26, two Virtual Router Redundancy Protocol (VRRP) backup groups are deployed on the access side. One VRRP backup group uses NE40E 1 as the master and NE40E 2 as the backup, and the other uses NE40E 2 as the master and NE40E 1 as the backup.

In multi-device backup scenarios, configure load balancing based on odd and even MAC addresses to enable the master NE40E 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 NE40Es in the same virtual local area network (VLAN) must use different virtual MAC addresses to establish sessions with hosts.
