Description

(EX8200 switches only) Enable multicast load balancing to evenly distribute the Layer 3 routed multicast traffic on aggregated 10-gigabit Ethernet interfaces. When multicast load balancing is enabled on the EX8200 switch, it takes effect on aggregated 10-gigabit Ethernet interfaces that are currently configured as well as those that are configured later.

Crc-sgip mode is the default. If the default mode is implemented and the Layer 3 routed multicast traffic on the aggregated interfaces is not evenly distributed, you can try the other hashing algorithms. Use the algorithm that best balances your Layer 3 routed multicast traffic.

Note:

If you change the hashing algorithm when multicast load balancing is disabled, the new algorithm takes effect after you reenable multicast load balancing.

Default

Multicast load balancing is enabled.

Options

hash-mode mode—Specify one of these hashing algorithms:

balanced

Use a round-robin method to determine the aggregated Ethernet links with the least amount of traffic.

crc-gip

Use multicast packets’ group IP address as a key to a CRC algorithm to get the hash index. The hashing algorithm used is CRC.

crc-sgip

Use multicast packets’ source IP address and group IP address for hashing. The hashing algorithm used is CRC.

crc-sip

Use multicast packets’ source IP address for hashing. The hashing algorithm used is CRC.

simple-gip

Use multicast packets’ group IP address for hashing. The hashing algorithm used is XOR.

simple-sgip

Use multicast packets’ GIP bits to calculate the hash index. The hashing algorithm used is XOR.

simple-sip

Use multicast packets’ source IP address bits for hashing. The hashing algorithm used is XOR.

The remaining statement is explained separately. See CLI Explorer.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 12.2 for EX Series switches.
