2.6.2 Example for Configuring Load Balancing Between Active and
Standby Links of a Smart Link Group
Networking Requirements
As shown in
standby link, and packets of other VLANs are transmitted through the active link. To ensure
network reliability, the customer network is dual-homed to the MAN. Packets of VLAN 100
and VLAN 500 are transmitted through the standby link, and packets of other VLANs are
transmitted through the active link. When the active link fails, packets on the active link can be
switched to the standby link quickly. When the standby link fails, packets of VLAN 100 and
VLAN 500 can be switched to the active link quickly. The service interruption duration is
restricted to millisecond level.
