Release Information Statement introduced in Junos OS Release 13.2X51-D15 for EX Series switches.
Statement introduced in Junos OS Release 13.2X51-D20 for QFX Series devices.
Description Select the payload fields in an IPv6 packet used by the hashing algorithm to make hashing
decisions.
When IPv6 traffic enters a LAG and the hash mode is set to Layer 2 payload, the hashing
algorithm checks the fields configured using this statement and uses the information in
the fields to decide how to place traffic onto the LAG bundle’s member links or to forward
traffic to the next hop device when ECMP is enabled.
The hashing algorithm, when used to hash LAG traffic, always tries to manage bandwidth
by evenly load-balancing all incoming traffic across the member links in the bundle.
The hashing algorithm only inspects the IPv6 fields in the payload to make hashing
decisions when the hash mode is set to Layer 2 payload. The hash mode is set to Layer
2 payload by default. You can set the hash mode to Layer 2 payload using the set
forwarding-options enhanced-hash-key hash-mode layer2-payload statement.
Default The data in the following fields are used by the hashing algorithm to make hashing
decisions for IPv6 traffic:
• IP destination address
• IP source address
• Layer 4 destination port
• Layer 4 source port
• Next header
Options no-ipv6-destination-address—Exclude the IPv6 destination address field from the hashing
algorithm.
no-ipv6-source-address—Exclude the IPv6 source address field from the hashing algorithm.
no-l4-destination-port—Exclude the Layer 4 destination port field from the hashing
algorithm.
