Load Balancing and Ethernet Link Aggregation Overview
You can create a link aggregation group (LAG) for a group of Ethernet ports. Layer 2 bridging traffic is load balanced across the member links of this group, making the configuration attractive for congestion concerns as well as for redundancy. You can configure up to 480 LAG bundles on a Juniper Networks MX Series Ethernet Services Router. Each LAG bundle contains up to 16 links.
By default, the hash key mechanism to load-balance frames across LAG interfaces is based on Layer 2 fields (such as frame source and destination address) as well as the input logical interface (unit). The default LAG algorithm is optimized for Layer 2 switching. You can also configure the load balancing hash key for Layer 2 traffic to use fields in the Layer 3 and Layer 4 headers using the payload statement, see Configuring Load Balancing on a LAG Link.In a Layer 2 switch, one link is overutilized and other links are underutilized.
