Context

Description
This command configures system-wide Layer 4 load balancing. The configuration at system level can
enable or disable load balancing based on Layer 4 fields. If enabled, Layer 4 source and destination port
fields will be included in hashing calculation for TCP/UDP packets.
The hashing algorithm addresses finer spraying granularity where many hosts are connected to the network.
To address more efficient traffic distribution between network links (forming a LAG group), a hashing
algorithm extension takes into account L4 information (i.e., src/dst L4-protocol port).
The hashing index can be calculated according to the following algorithm:
If [(TCP or UDP traffic) & enabled]
hash (<TCP/UDP ports>, <IP addresses>)
else if (IP traffic)
hash (<IP addresses>)
else
hash (<MAC addresses>)
endif
This algorithm will be used in all cases where IP information in per-packet hashing is included (see
LAG
and ECMP Hashing in the Interfaces Guide
). However the Layer 4 information (TCP/UDP ports) will not be
used in the following cases:
• Fragmented packets

Description
This command enables enhanced egress multicast load balancing behavior for Layer 3 multicast. When
enabled, the router will spray the multicast traffic using as hash inputs from the packet based on lsr-load-
balancing, l4-load-balancing and system-ip-load-balancing configurations, namely an ingress LER or IP PE
will spray traffic based on IP hash criteria: SA/DA + optional L4 port + optional system IP egress LER or
